Hi, I am using the densCols to draw a high volume scatter plot. Instead of using the default local density, I would like to take log of the local density and then map them to the colors. I could not figure out how to do that. For example: plot(x,y,col=densCols(x,y,"log")) ? Any help would be appreciated! Jiaxiu [[alternative HTML version deleted]]

Any idea why I can no longer plot two graphs on the same graphics device using the par(fig=) parameter? A simpler par(mfrow=c(1,2)) does work, showing the two plots side-by-side, but I would like the first to be larger. This simple example fails: x<-c(1,1,NA,2,2,NA,3,3) y<-c(2,4,NA,3,5,NA,1,4) par(fig=c(0,2/3,0,1)) plot(x,y) par(fig=c(2/3,1,0,1)) qqnorm(x) When plotted, the last

Is there any way to control the spacing between bars in a histogram, or change the border width (I'm assuming the hist() function, though alternatives are welcome)? I'm interested in changing the visual spacing between columns in a plotted histogram. The general effect I'm looking for can be accomplished in barplots using the "width=" parameter, but I have not been able
