help to speed up loops in r
Hi
i am using a script which involves the following loop. It attempts to reduce a data frame(zz) of 95000 * 41 down to a data frame (averagedreplicates) of 95000 * 21 by averaging the replicate values as you can see in the script below. This script however is very slow (2days). Any suggestions to speed it up.
NB I have also tried using rowMeans rather than adding the 2 values and dividing by 2.
