Using "mean" if two values are identical
Hello,
I have got a question.
I've got a matrix (mail end) with the colnames x, y, z. In this matrix
are different measurements. x and y are risign coordinates.
My question. Always, if the "x" AND "y" coordinates are the same, I want to
get the mean of their z values.
e.q. "
x" AND "y" in line1 and line8 are identical:
29 4.5 --> mean of 1.505713 and 1.495148
Thank's a lot.
Felix

Get the difference of values to their own median value
Hello,
I've got a matrix (mail end) with the colnames x, y, z. In this matrix
are different measurements. x and y are risign coordinates.
With the following line I got the median value of z for all "x" AND "y" witch
are the same (not every measurment in my list hast the same number of
"x" and "y" values. Sometimes lines are missing.
