Re: [R] error bars in matplot

Hi Tim, there are a couple of problems in your example. (1) The most important is that your 'x' values for the matplot are 1:5 (that is row numbers of your mat1 matrix) and are seq(20,100,20) (that is, your vect vector) for your error bars. Error bars are thus plotted outside the plotting are
