From there it's a simple matter of plotting our data as a barplot (geom_bar()) with error bars (geom_errorbar())! Other e.g.: r plot share|improve this question edited Nov 5 '13 at 20:35 asked Nov 5 '13 at 20:02 Alan Valejo 4902622 closed as too broad by Señor O, plannapus, ithcy, Let's assume you have a vector of "average values" avg and another vector of "standard deviations" sdev, they are of the same length n. After this, we construct a ggplot object that contains information about the data frame we're using as well as the x and y variables. http://lebloggeek.com/error-bars/scatter-plot-with-error-bars-r.html

The regular error bars are in red, and the within-subject error bars are in black. # Instead of summarySEwithin, use summarySE, which treats condition as though it were a between-subjects

If it is a numeric vector, then it will not work. # Use dose as a factor rather than numeric tgc2 <- tgc
