Re: [R] Coarsening the Resolution of a Dataset

I assume that you are doing this on one column of the matrix which should only have 2160 entries in it. can you send the actual code you are using. I tried it with 10,000 samples and it works fine. So I need to understand the data structure you are using. Also the infinite recursion sounds strange; do you have function like 'cut' or 'c' redefined? So it would help if you could supply a reproducible example.
