Hi, I cannot seem to figure out how to sum over an index of a array. For example, let A be a 3 dimensional array. I want to, say, find the sum over the first dimension. That is
S_jk = Sum_i A_ijk where now S is a 2-dim matrix. I dont want to use a loop. Thanks, -- saurav ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
