FWIW, that behavior vis-a-vis \Sexpr{} and "$" characters has been in place for "years".

The way that I avoid it is to create a result object in an R chunk before the LaTeX chunk, so that the "$" is not needed within the \Sexpr{}.

An alternative might be to use with(DF, ColName) in the \Sexpr rather than DF$ColName.
