Hi, I have a vector of p*(p+1)/2 elements, essentially the lower triangle of a symmetric matrix. I was wondering if there is an easy way to make it fill a symmetric matrix. I have to do it several times, hence some efficient approach would be very useful.
Many thanks and best wishes, Ranjan ______________________________________________ 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.
