Sorry 'bout that. Here's about as simple as I can get it:
#First dataset N <- 25 x <- round(rnorm(N),2) y <- round(rnorm(N),2) df <- data.frame(x = x, y = y) #Plot it xyplot(df$x~df$y,xlab="Test 1 Data",ylab="P(A>A*)") #Second Dataset N <- 20 x <- round(rnorm(N),2) y <- round(rnorm(N),2) df <- data.frame(x = x, y = y) #How to get this in the same panel as plot 1? xyplot(df$x~df$y,xlab="Test 2 Data",ylab="P(A>A*)") As far as combining that data into one dataset....I'm trying to plot both datasets into one panel to show the differences in the plots of the two...utilizing the coloring/symbology funtions...wouldn't combining them null that capability? Thanks for your replies!

Please construct a reproducible worked example that does not require us to download 7 Mb of data. You might also try the suggestions that I made and let us know if they worked for you.
