Code highlighting with Sweave; using $ in \Sexpr not working properly #490

Open GoogleCodeExporter opened 9 years ago

This report concerns Sweave (Rnw) files.

When you use $ in \Sexpr{}, then the highlighting assumes that it starts a math 
environment. However it has a different meaning in R code.

E.g. \Sexpr{data$sub} already messes up the highlighting afterwards.

Expected behaviour:
Code should not be highlighted in \Sexpr{} or similar Sweave "commands" at all 
(as it is done for the main Sweave block, between <<>>= and @).

Bug is present in 3.2.2.
I have attached a snapshot that shows this bug and the Rnw file I used to 
reproduce this.
