bitmap(file="barplotx.jpg",type="jpeg")
barplot(c(1,2,3),c(3,4,5),main=list("Death Rates in Virginia", font = 1))
dev.off()My question: How can I improve the sharpeness of the text "Death Rates in Virginia".
Why jpeg: Its part of a web-environment using R through a SOAP-server. I also tried png256, jpeggray and others, but the text "Death Rates in Virginia" does not change sharpeness.

There are two ways to make jpgs in R: which did you use?
If you want a sharp image, why are you using a format designed for photographic images?
I suspect your viewer: that example seems as sharp as I would expect viewed in a high-quality JPEG viewer on my LCD screen.
