As was pointed out your attachment didn't make it to the list, so we
don't know what you want plotted, and your problem statement wasn't
clear (at least to me).
Usually, it you want help on this list, you should provide a
reproducible example. In your case, at least show us what you tried.
If you provide code to generate your random samples, and then describe
what you want, e.g. "plot sample means and standard errors estimated
from the samples," we can play along at home. Then you may get some
You could also Google something like "R plot means and standard errors".
