I want to check whether all the components of a vector (or an array) are 0, and if they are I will skip the later computations. Of course I can create a loop to go through all the components. However is there an R function for this purpose more efficient than looping?
Thanks a lot, Gang ______________________________________________ R-help@stat.math.ethz.ch 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.
