[R] thanks!! get mean of several rows

[Jan Wantia]

Dear all!

Thanks to all who replied to my question on getting the means of several 
rows, and the one with the standard error + mean-plot!
Many of them worked fine just as they were, others had to be adapted a bit.
However, I can finally do my calculations, and find myself happy as a 
man could be, plotting fancy graphs whole day long.
Moreover, I think I have learned quite a bit on R, seeing so many ways 
to do the same thing.
Thanks a lot, again, I was really at the edge of going home and get drunk!

Cheers, Jan
