To install and load r2k from GitHub:

devtools::install_github("vandomed/r2k")
library("r2k")

The idea is to provide functions that work just like common base R functions, like table and glm, but that immediately produce clean kable printed to the RStudio Viewer or to an R Markdown document.

Each function has two variants: <function>_v and <function>_k. The _v version (for “Viewer”) prints to the Viewer but still returns the object you’d expect from <function>. The _k version (for “kable”) returns a kable which should print nicely without any further steps in R Markdown/knitr documents.

If you swap in table_v for table, the results print neatly to the Viewer:

df <- table_v(mtcars$cyl, mtcars$gear)

From there, if you want to export the table out of R, you could “snip” the table and save it as a figure (as I did for this README) or copy directly from the Viewer and paste outside of R. In my experience, output from the Viewer pastes nicely into Word, Excel, and PowerPoint.

Similarly, you can use table_k in R Markdown documents to quickly generate kable outputs without any extra steps.

The namesake function is very simple: it just converts R objects to kables by calling kable and kable_styling. To print out the 4-cylinder cars in mtcars, using dplyr and piping:

mtcars %>%
  dplyr::filter(cyl == 4) %>%
  r2k()
