These values can diverge when there are between-subject variables. I will work through your suggestions. –James Waters Nov 2 '11 at 20:21 add a comment| up vote 3 down vote [Potential shameless promotion] You should consider the functions compareCats and The spacings of the two scales are identical but the scale for differences has its origin shifted so that zero may be included. First of all, you don't have to calculate the means by hand. http://vealcine.com/error-bar/r-plot-error-bars-scatter-plot.php

  • Details errbar adds vertical error bars to an existing plot or makes a new plot with error bars.
  • Plot from the ?rxnNorm example included here.

It can also make a horizontal error bar plot that shows error bars for group differences as well as bars for groups. lineplot.CI(variable,value, group =sex.codes , data = df.2, cex = 1.5, xlab = "Location", ylab = "means", cex.lab = 1.2, x.leg = 1, col = c("blue","red"), pch = c(16,16)) share|improve this answer What you calculate, is not the standard error on your prediction.
