Hi
I have tried many attempts but cant get the loop right, as I am not a strong
programmer. What I am basically trying to do is compare 2 spreadsheets. The
problem is that one of them only contain a portion of the overall data
(TESTSAMP), where the other has a full datasetFULLSAMP. From the complete set I
would like to remove the rows of data which are not in the TESTSAMP. Column 1
contains the sample numbers which can be used to identify samples. Does anyone
have any suggestions?
I have tried various things like double loops and so on, but I am sure there is
an easier way or function to do this.
i tried this method, but Im not sure how to only keep looping until a match is
found. I dont understand how repeat loops work in R.
for (i in 1:length(FULLSAMP[,1])) {
if (FULLSAMP[i,1] != TESTSAMP[i,1]) {
FULLSAMP <- FULLSAMP[-i,]
}
Thanks in advance
