Manuel, Thanks, this worked well. I was also toying around with other options in bargraph.CI per your suggestion.
Thanks, Michael bargraph.CI(RecovUnit, bbED, group = year, data =scape234, + xlab = "Recovery Unit", ylab = "Edge Density", cex.lab = 1.5, x.leg = 1, + density = c(0,20), legend = TRUE) On Wed, Oct 8, 2008 at 2:28 PM, Manuel Morales < [EMAIL PROTECTED]> wrote: > On Wed, 2008-10-08 at 12:01 -0500, Michael Just wrote: > > Thank you all for you suggestions.
