-### Usage
-
-The package consists of two functions:
-
-1. `letterToNumber` - converts letters in a string to numbers
-2. `numberToLetter` - converts numbers in a string to letters
-
-Both functions convert non-alphanumeric characters to dash (-) and perform no
-conversion on their respective base character type (i.e., `letterToNumber` 
-leaves letters as is and `numberToLetter` leaves numbers as is).
-
-### Examples
-
-```{r library, echo=FALSE}
-library(phonenumber)
-```
-
-**`letterToNumber`** converts a string containing letters into the corresponding 
-numbers on a telephone's keypad. For example, if the user wants to know what 
-telephone number corresponds to "Texas:"
-
-```{r letterToNumber}
-string <- "Texas"
-letterToNumber(string)
-```
-
-**`numberToLetter`** converts a string containing numbers into the corresponding 
-letters on a telephone's keypad. For example, if the user wants to know what 
-possible character strings could be spelled by a sequence of numbers (e.g., 22):
-
-```{r numberToLetter ex1}
-string <- "22"
-numberToLetter(string)
-```
