See ?plotmath for some additional examples and there are some others in the list archives. set.seed(1) x <- rnorm(1000000) # Now do the plot, but leave the x axis blank plot(x, xaxt = "n") # Set the x axis label tick marks x.at <- seq(0, 10, 2) * 10 ^ 5 # Create the expressions for the tick mark labels # Using parse() takes the character vectors from paste() # and converts them to expressions for use in plotmath x.lab <- parse(text = paste(seq(0, 10, 2), "%*% 10^5")) # Now do the axis labels axis(1, at = x.at, labels = x.lab) HTH, Marc Schwartz ______________________________________________ R-help@stat.math.ethz.ch mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide! http://www.R-project.org/posting-guide.html
