Hi Welma,
You need to escape the % sign, just as you would if you were writing
the table by hand. You can do this using gsub, e.g.:
Data <- data.frame(X = paste(1:10,"%",sep=""),Y=paste(rnorm(10),"%",sep=""))
Data$X <- gsub("%","\\\\%",Data$X)
Data$Y <- gsub("%","\\\\%",Data$Y)
library(xtable)
print(xtable(Data))

Also, regarding your initial issue with the wide table: consider
printing the table sideways instead of shrinking it. See the Sweave
examples vignette for an example.
