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 ylim (numeric of length 2): the y-axis extents with a sensible default.

You should better use the errbar function from the Hmisc package: d = data.frame( x = c(1:5) , y = c(1.1, 1.5, 2.9, 3.8, 5.2) , sd = c(0.2, 0.3, 0.2, more stack exchange communities company blog Stack Exchange Inbox Reputation and Badges sign up log in tour help Tour Start here for a quick overview of the site Help Center Detailed it took me some time to reproduce your results with my own data as in my data the columns are NOT named "x" and "y", which (apparently) means that for the R Plot Standard Deviation xlab optional x-axis labels if add=FALSE.

The only two things my function did that these calls don't do is (1) to size the plot appropriately so the upper and lower limits of the errors are within the For the latter type of plot, the lower x-axis scale corresponds to group estimates and the upper scale corresponds to differences.
