typingtutor is an R package that provides typing exercises based on R packages on github. Its purpose is to increase the user's speed of typing in general and typing R code in particular, with the side bonus of gaining familiarity with the code underlying successful R packages.

The typingtutor website

As typingtutor is only available on Github, the easiest way to install it is via devtools:

install.packages("devtools")
devtools::install_github("baogorek/typingtutor")

After starting R, load the typingtutor library:

library(typingtutor)

To practice typing on the Github repo tidyverse/dplyr, simply enter

type_github()

or, for another repo, enter the Github repository path as an argument:

type_github("stefvanbuuren/mice")

The user is presented with a choice of R files and then groups of R expressions within those files for which to type on. A maximum of 1000 characters will be presented to the user, and functions longer than 1000 characters are truncated.

You can always get to the typingtutor companion website by typing visit_site() in R or by visiting

https://baogorek.github.io/typingtutor/site/signed-in.html

which will redirect to

https://baogorek.github.io/typingtutor/

if the user is not signed in. Currently, a Github account is required for authentication to the typingtutor companion page.

After practicing on a typing tutor expression group, the user will be given the option to save to the typingtutor companion page. For the first time in every new R session, the user will have to enter a "authentication metadata string" at a prompt. Once signed into the typingtutor companion webpage, this is accomplished by clicking the green button, pressing CTRL + C and Enter, and pasting the resulting string back into the R prompt.

Saving is optional, and the user may use the typingtutor without ever saving to the typingtutor companion webpage.
