That may be a better solution, but I don't think
it is clearly a better solution.
I presume you mean that your computation is the
most time efficient. That seems believable to me.
It is not the most human efficient -- it will take
some one reading the code non-trivial effort to
understand it.
Try with plotmeans in gplots
