You should almost never need to modify valid R code to work with Sweave.
(There are a few exceptions: code that illustrates errors, or code that
requires interaction with a user, etc.)
There's nothing wrong with including mydata$somevar in an Sweave code
chunk.

There is nonetheless a point to what she is suggesting. In my experience the
$ tends to confuse the editor so the highlighting gets confused amongst other
things
If 'the editor' is emacs + ESS, it sometimes happens that the chunk vector
needs to be updated and that until it is some dollar signs will be seen as
LaTeX by the syntax highlighting.
If this is your problem,
Noweb --> Miscellaneous --> Update the Chunk Vector
or
M-n C-l
should fix it.
