Not sure why but in some of my R Scripts a coloured box is appearing over random words within ""

For example:

If I just write the word blue then it appears normally. Only gets this box over it when in quotation marks.

In a different R script it is happening with the "peru"

Dont believe I have changed any settings. Seems to persist even if I clear the global environment.

CodePudding user response：

blue and peru are both colors as you can verify in

plot(1:3, col = "peru", pch = 15, type = "b", lwd = 3)

So RStudio is just helping you by displaying the color refrerenced in the code
