R - Conditional row highlighting in HTML table created using xtable or kable

Question

I\'m pretty much a beginner at programmatically formatting R output, but I\'ve got a basic understanding of knitr, xtable, Markdown, and Pandoc\'s

Answer 1

Well, not using colors (as not supported by markdown), but you can highlight cells/rows/columns of the table with pandoc.table and the general pander method by using bold or italics font face:

> library(pander)
> emphasize.rows(which(df$outcome == 2))
> pander(df)
