It's also a good habit to specify the upper bounds of your plot since the error bars are going to extend past the height of your bars.

ylim (numeric of length 2): the y-axis extents with a sensible default. lwd line width for line segments (not main line) pch character to use as the point. 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 Wouldn't it be nicer if we could group the bars by number of cylinders or number of gears?
