Installation of the FastinR package

[LoouiseM]

Dear authors,

I am trying to install the FastinR package and I am facing an issue during the installation of the package.

This is the script for the installation of all necessary packages:
library(usethis)
library(devtools)
library(rjags)
library(lme4)
library(GGally)
require('devtools')
install_github("philipp-neubauer/fastinR/fastinR")

And this is the error occurring when I run the last command:
Error: (converted from warning) package ‘rjags’ was built under R version 4.0.2
Execution halted
ERROR: lazy loading failed for package ‘fastinR’

• removing ‘/Library/Frameworks/R.framework/Versions/4.0/Resources/library/fastinR’
  Error: Failed to install 'fastinR' from GitHub:
  (converted from warning) installation of package ‘/var/folders/rm/gqgn7gzx3hvf9rg_kw_qx_w40000gn/T//RtmpPqznTI/fileb7743dcb9/fastinR_0.4.tar.gz’ had non-zero exit status

Would you have any idea on how to solve this issue ? I am using the last version of RStudio on a Macbook, and both XQuartz and Xcode-beta are installed.

Thank you in advance,

Louise

Hi Louise -

it seems an issues with the rjags install not being compatible. What R version are you running?

Also, I would recommend trying the more recent version on the stan branch of this repo. I have just made that the default, so that a remotes::install_github("philipp-neubauer/fastinR/fastinR") should install the stan branch. If not, you may need to specify the branch in that command. You'll need a working install of rstan for that branch to work as I switched the backend from rjags to rstan.

Hope this helps
Phil

Hi Philipp,

Thank you very much for your answer.

I am using the R version 4.0.0.
I followed your recommendation and the installation of the package worked!

Thank you so much for your help,
