If you google something like “pretty tables in R”, you will find a number of R packages that create HTML type code that can be saved as an HTML file, a PDF file, or another file format. Much has been written about these packages, but they seem a little complicated for basic work, and further, I like the idea of staying exclusively within the R environment. When I realized a table is just a collection of rectangles, it occurred to me that the base R commands of rectangle and text are pretty much all I need.
