[R] ggplot2 plotting errorbars.

[Rafael Robledo]

Hi, it seems to be a problem about using aes both in ggplot as also in geom_bar.

You could specify fill property for your geom_bar in ggplot
initialization, in order to avoid this issue
(you could also do the same thing for ymin and ymax properties for
errorbar :P), i.e:

dodge <-position_dodge(width=0.9)

ggplot(dfm, aes(x=X, y=value, fill=variable, ymin=value-er, ymax=value+er)) +
  geom_bar(position=dodge) +
  geom_errorbar(position=dodge, width=0.25)

Hope it helps.
