rresutils

The goal of rresutils is to support teaching of R using Quarto/R Markdown.

Installation

You can install the released version of rresutils from GitHub with:

devtools::install_github("rressler/rresutils")

or

remotes::install_github("rressler/rresutils")

Examples

The package has two sets of similar functions. These are based on ideas and code samples in section 17.5 of the R Markdown Cookbook

quarto_render() Functions

rres_render_solutions()

• This function outputs two versions of an .qmd file that has been configured to use a YAML parameter called params:solutions where the values are either true or false. These values turn code chunk options such as eval, echo, or include on and off respectively.

Use the console to run rresutils::rres_render_solutions("my_path/file.qmd").

• The file with solutions will have "_solutions" in the file name.
• The file without solutions will have "_student" in the file name.

The default file extension is "html" but you can change to another extension with argument fext = "pdf".

rres_render_solutions_date()

This function operates the same as rres_render_solutions() but it appends the Sys.Date() value at the end of the file name.

Use the console to run rresutils::rres_knit_solutions_date("my_path/file.qmd").

rmarkdown::render() Functions

rres_knit_solutions()

• This function outputs two versions of an .Rmd file that has been configured to use a YAML parameter called params:solutions where the values are either TRUE or FALSE. These values turn code chunk options such as eval or echo on and off respectively.

Enter the following into the YAML header and then knit. It will use the first output type in your YAML be it PDF or HTML. The file with solutions will have the "_solutions" in the file name.

knit: rresutils::rres_knit_solutions

rres_knit_solutions_date()

This function operates the same as rres_knit_solutions() but it appends the Sys.Date() value at the end of the file name.

Enter the following into the YAML header and then knit. It will use the first output type in your YAML be it PDF or HTML. The file with the solutions will have "_solutions" in the file name. Both files will have the current date added to the file name.

knit: rresutils::rres_knit_solutions_date
