@Olivier ETERRADOSSI : I tried "gdata" to convert a (10000x10000) lower triangular matrix to full matrix and got memory problems. Especially at this step :
upperTriangle(a) <- lowerTrangle(a) it consumes more than 3 GB . Any ideas on how to create full matrix with efficient memory management ? -- View this message in context: http://r.789695.n4.nabble.com/how-to-convert-the-lower-triangle-of-a-matrix-to-a-symmetric-matrix-tp823271p4118621.html Sent from the R help mailing list archive at Nabble.com. ______________________________________________ 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.
