How to disable message null device when using R and latex.

<<echo=FALSE ,results=tex>>=
data<-read.table("test",sep="\t",header=TRUE,check.names=FALSE)
names(data)<-substr(names(data),1,20)
pdf("image.pdf")
par(las=2)
par(mar=c(2,12,2,2))
barplot(as.matrix(disease_data),beside=TRUE, col=c("burlywood1 ","orange2"), horiz=TRUE,cex.names=1.0, border ="white")
dev.off()

echo=FALSE only hides the R code; if you want to hide the output, you should use results=hide.

But why do you have to use pdf() and dev.off() to manually create a PDF plot? This is too awkward. You should leave this job to Sweave.

Now i am using sweave but i can not reduce image size that is why i am using includegraphics by passing width and height to control its size. Is there any way to reduce plot size in R? – manish Apr 25 '12 at 2:51
yes, that is one of the tiny reasons which motivated my knitr package, which allows you to control the size of your plots easily; see yihui.name/knitr or the manual github.com/downloads/yihui/knitr/knitr-manual.pdf – Yihui Apr 25 '12 at 5:28
