Syntax highlighting themes
This object can be used to set or get themes in knitr for syntax highlighting.
knit_theme
An object of class list of length 2.
We can use knit_theme$set(theme) to set the theme, and
knit_theme$get(theme) to get a theme. The theme is a character
string for both methods (either the name of the theme, or the path to the CSS
file of a theme), and for the set() method, it can also be a list
returned by the get() method. See examples below.
The syntax highlighting here only applies to ‘.Rnw’ (LaTeX) and ‘.Rhtml’ (HTML) documents, and it does not work for other types of documents, such as ‘.Rmd’ (R Markdown, which has its own syntax highlighting themes; see https://rmarkdown.rstudio.com).
