[R] replace "%" with "\%"

[Liviu Andronic]

Thanks all for the prompt responses. Now Hmisc::latex() no longer
generates errors on Rcmdr::numSummary() objects (with `tempa' below
being such an object).
> colnames(tempa$table) <- gsub("%", "\\%", colnames(tempa$table), fixed=TRUE)
> latex(tempa$table, cdec=3)

Best regards,
Liviu
