tableone 0.10.0 (2019-02-16)
----------------------------------------------------------------

BUG FIXES

* Fix a missing value handling issue (via @chipmanj).
  Closes issue #26.

* mean (sd) was changed to mean (SD) to be consistent with
  median [IQR].

NEW FEATURES

* Add a helper for exporting TableOne objects to Markdown
  (via @malcolmbarrett). Currently, this is very basic. We hope
  to extend its functionalities.

* README.md now lists similar or complementary projects.


tableone 0.9.3 (2018-04-28)
----------------------------------------------------------------

BUG FIXES

* Fix incompatibility with lmerTest package (via @runehaubo).
* Suppressed "No sampling weights provided" warning on svrepdesign.


tableone 0.9.2 (2018-01-24)
----------------------------------------------------------------

BUG FIXES

* Address CRAN test issues on some platforms.
* Fix typos (via @LucyMcGowan)


tableone 0.9.1 (2017-11-06)
----------------------------------------------------------------

BUG FIXES

* ExtractSmd always returns a matrix even when there are only two
  groups for easier subsequent data manipulation.


tableone 0.9.0 (2017-11-03)
----------------------------------------------------------------

NEW FEATURES

* The "varLabels" option for the print.TableOne method was added.
  When TRUE, instead of printing the variable names, their
  corresponding variable labels are used. Variable labels must be
  stored in the data frame to be used via labelled::var_label
  function. This option is also available in ExtractSmd function.

* The "dropEqual" option for the print methods was implemented. If
  TRUE, the level description for two-level variables such as " = 1"
  and " = TRUE" are not shown. This can obscure what level is being
  shown depending on the variable naming scheme, thus, should only
  be used after the initial results were checked for correctness.

BUG FIXES

* Handling of lme4 models was improved in ShowRegTable.


tableone 0.8.2 (2017-08-31)
----------------------------------------------------------------

BUG FIXES

* Handle labelled class as categorical.


tableone 0.8.1 (2017-06-17)
----------------------------------------------------------------

BUG FIXES

* Fix alignment issue with the Missing column. Note currently the
  percentage is shown with 1 decimal and this is hard-coded.

* Change vignetteBuilder to knitr to form the index correctly.

* Single-quote package names in DESCRIPTION.


tableone 0.8.0 (2017-06-15)
----------------------------------------------------------------

NEW FEATURES

* The "missing" option for the print methods was implemented. If
  TRUE, a column called "Missing" is added as the rightmost column
  of the formatted table. This represents percentage of missing
  observation in each variable. Please note this is the percentage
  with respect to the unweighted raw observations even in weighted
  tables.

* The "padColnames" option was added the print.TableOne method. If
  TRUE, the column names of the formatted table become space-padded
  to center them.


tableone 0.7.6 (2016-07-12)
----------------------------------------------------------------

BUG FIXES

* The explanation for the "factorVars" argument for the functions
  CreateTableOne and svyCreateTableOne were changed for clarity.
  When factor variables are included in the argument, they are
  releveled to exlude empty levels. This was not clearly documented
  in the previous documentation. Thanks @eribul.

* svyrep.design objects (survey design objects with replicate weights)
  are allowed for the data argument in svyTableOne. This is considered
  experimental. Thanks @przemo.


tableone 0.7.5 (2016-04-10)
----------------------------------------------------------------

BUG FIXES

* ShowRegTable() now correctly supports models fit with geepack,
  nlme, and lme4.


tableone 0.7.4 (2016-03-31)
----------------------------------------------------------------

NEW FEATURE

* Define SMD := 0 when the numerator is 0 even if the denominator
  is also 0. This is more intuitive because a constant compared
  across two groups will give an SMD of 0 rather than NaN (0/0).
  For example, if two groups being compared both only have one
  gender (all female or all male), then SMD for the gender
  variable is defined as 0.


tableone 0.7.3 (2015-11-10)
----------------------------------------------------------------

BUG FIXES

* Fix the vignette for upcoming ggplot2 update.


tableone 0.7.2 (2015-10-25)
----------------------------------------------------------------

BUG FIXES

* Solve errors with abnormal pooled variance-covariance matrices
  in standardized mean difference calculation.


tableone 0.7.1 (2015-08-11)
----------------------------------------------------------------

BUG FIXES

* Solve problems with unit testing on the sparc architecture
  without extended-precision arithmetic support.

* Fix title for second vignette.


tableone 0.7.0 (2015-08-10)
----------------------------------------------------------------

NEW FEATURES

* Weighted data are now supported via the survey package.
  svydesign() should be used to create a survey design object,
  and this object should be used for svyCreateTableOne() instead
  of a data frame. Other options are essentially the same. All
  results will be weighted results.

* Standardized mean differences are calculated. print() methods
  include smd option, which defaults to FALSE for backward
  compatibility. If TRUE, SMD is shown on the right side of the
  table. To suppress p-values, use test = FALSE option.
  summary() methods also print SMDs. If there are more than two
  strata, all possible pairwise contrasts are shown along with the
  average SMD across all contrats. In this case, print methods only
  prints the average SMD for brevity. For categorical variables
  Yang and Dalton's suggested method (A unified approach to
  measuring the effect size between two groups using SAS.
  SAS Paper 335-2012) is used. SMDs for weighted data are
  experimental.

* ExtractSmd() function can be used to extract SMD values as a
  numeric matrix, which then can be used for plotting, etc.

* An new RMarkdown vignette explains the use of standardized
  mean differences.

* The includeNA option for CreateTableOne() and svyCreateTableOne()
  make NA's in factors treated as a regular level.

* ShowRegTable() now has ciFun option, which allows use of
  the confint.default function if calculation is too slow for
  glm results.

* print.TableOne() aligns the sample size with other summaries.


OTHER CHANGES

* ShowRegTable() uses coef to refer to coefficients.

* Unit tests were extended to cover more functions.

* CreateTableOne() was refactored to avoid redundant calculation.

* New dependencies: survey, MASS, and zoo


BUG FIXES

* Fixed pDigits option in print.ContTable(), which was not correctly
  functional as advertised.


tableone 0.6.3 (2014-12-28)
----------------------------------------------------------------

DOCUMENTATION

* An RMarkdown vignette outlining the use of the package was added.


tableone 0.6.2 (2014-06-01)
----------------------------------------------------------------

BUG FIXES

* The testing of 1 x m table was problematic when a categorical
  variable only have one level. chisq.test() returns Chi-squared
  test for given probabilities (test for strata imbalance) in such
  cases. In this version, testing a 1 x m table always return NA,
  as test for a cross table is not defined in this context.

* Special thanks to Atsushi Shiraishi for reporting this issues.

* Unit testing with the testthat package was added for some
  functions. Thus, the testthat package was added as a suggested
  package.


tableone 0.6.1 (2014-06-01)
----------------------------------------------------------------

BUG FIXES

* The algorithm CreateCatTable used to detect variables to convert
  to factos had a bug. CreateCatTable was effectively (re-)converting
  all variables to factors, which deleted empty levels from factors
  and ordered factors.

* Special thanks to Atsushi Shiraishi for reporting this issues.


tableone 0.6.0 (2014-05-31)
----------------------------------------------------------------

NEW FEATURES

* The CreateTableOne function automatically use all variables
  in the data frame given to the data argument, if the vars
  argument is empty.
* The printToggle argument added to ShowRegTable().


tableone 0.5.0 (2014-04-14)
----------------------------------------------------------------

NEW FEATURES

* The noSpaces argument was added to print.* functions. This allows
  removal of spaces added for alignment using fixed-width fonts.
  Use this option if you prefer to align your table in other software.
  (Special thanks to Raja Sriswan Mamidi for suggestions)


tableone 0.4.0 (2014-03-30)
----------------------------------------------------------------

NEW FEATURES

* The showAllLevels argument to show all levels of categorical
  variables regardless of numbers of levels was added to
  print.TableOne. Previously, it was only available in
  print.CatTable. To accommodate this feature, insertLevel argument
  to insert an empty level column was added to print.ContTable.
  (Special thanks to Yoshinobu Kanda for suggestions)


tableone 0.3.5 (2014-03-07)
----------------------------------------------------------------

BUG FIXES

* Fixed a problem with space insertion when empty strata are present.

* Thanks Joris Muller for bug reports and code suggestions for the
  following.

* Added more robust class assessment in CreateTableOne and
  CreateCatTable, which now handles ordered factors correctly.
  CreateTableOne also drops Surv object for safety.

* "Dropped due to unsupported class" message has been fixed to
  show variable names with spaces in between.


tableone 0.3.4 (2014-03-04)
----------------------------------------------------------------

BUG FIXES

* Added the Create* functions handling of all NA/NaN variables.
  These invalid variables are examined at the beginning and dropped
  with warning for safety.

* For the strata argument, variables with only one level is dropped
  with warning because these are meaningless, and caused data
  handling problems.


tableone 0.3.3 (2014-02-22)
----------------------------------------------------------------

BUG FIXES

* CreateTableOne now handles logical and chracter vectors correctly.
  They are handled as categorical variables, and passed to the
  CreateCatTable function. Variables that are none of numeric,
  integer, factor, logical, or character are dropped for safety.


tableone 0.3.2 (2014-02-18)
----------------------------------------------------------------

BUG FIXES

* DESCRIPTION changed for clarity. No functional changes.


tableone 0.3.1 (2014-02-18)
----------------------------------------------------------------

BUG FIXES

* NAMESPACE now includes import(e1071) and import(gmodels).

* DESCRIPTION now includes Imports e1071, gmodels and
  Suggests survival, instead of Depends...


tableone 0.3.0 (2014-02-17)
----------------------------------------------------------------
NEW FEATURES

* CreateTableOne has a new factorVars argument, a character
  vector specifying numerically coded variables that should be
  treated as factors.

* The print method for the TableOne/CatTable class object has a
  new minMax argument, a logical value specifying whether to show
  median [min, max] instead of median [IQR] for nonnormal variables

* The print method for the TableOne/CatTable class object has a
  new cramVars argument, a character vector to specify which
  2-level factors to should have both levels presented in one row.


BUG FIXES

* Documentations were fixed to represent the current version.


tableone 0.2.1 (2014-02-15)
----------------------------------------------------------------
BUG FIXES

* Documentations were fixed to represent the current version.


tableone 0.2.0 (2014-02-14)
----------------------------------------------------------------
NEW FEATURES

* CreateTableOne and related print/summary methods were added.

* CreateTableOne can crate a table with both categorical and
  continuous variables.

* The print method can suppress printing by printToggle option.

BUG FIXES

* In the Roxygen part of the code, only at_export followed by nothing is used.


tableone 0.1.2 (2014-02-09)
----------------------------------------------------------------
BUG FIXES

* Fixed incorrect specification of S3 method export.

* To make an object an S3 method and export it both at_S3method and at_export
  tags are needed in the Roxygen part of the code.

* Passed all the default tests by R CMD check file.tar.gz


tableone 0.1.1 (2014-02-09)
----------------------------------------------------------------
BUG FIXES

* This version is to better conform to the CRAN standards.

* Documents are now included in


tableone 0.1.0 (2014-02-08)
----------------------------------------------------------------
FIRST DEVELOPMENTAL VERSION

* This is the first developmental version to be made public.

* tableone makes creation of "Table 1", description of baseline characteristics
  common in medical research papers easy.
