I'd like to do a simple scatter plot but instead of using the variable values on the X axis I would like to plot the percentiles. I searched in the manual for percentiles but did not find what I was looking for. I've been using SAS for several years but I new to R.

Here is a hack par(mfrow=c(1,2)) x <- rnorm(1000) y <- x + rnorm(1000) xp <- (rank(x)-1)/(length(x)-1) plot( x, y ) plot( xp, y ) But do notice that by using percentiles, it spreads the 'x' values evenly. This may be important for points at the extremes. Regards, Adai
