Hi, I am using 'hist' to make a frequency histogram from my background-substracted foreground values. I want to highlight the first bar in the histogram. That's easily accomplished... unless the first bar is of negative values, then teh bar can't get coloured. It's either all coloured or nothing. what I do is something like this: hist(RG.s$R,col=c("darkblue",rep("white",14))) this one contains only positive values, and paints the first bar blue, and teh rest white. but if the RG.s$R vector contains some negative values, then the bar at the left of the 0 (negative counts) doesn't get coloured. However, if I do: hist(RG.s$R,col="darkblue") it paints all of them blue... so teh first bar can be painted so... anybody knows how can I get around this?

Agh, ignore this... I needed a coffee... it works just fine, it's just that the first bar was so tiny it didn't really show at teh scale I was drawing, so the bar I was looking at was actually the second. Doh!
