Good day, I have a real scenario involving 45 million biological cells (samples) and 60 proteins (variables) which leads to a segmentation fault for svd. I thought this might be a good example of why it might benefit from a long vector upgrade.
test <- matrix(rnorm(45000000*60), ncol = 60) testSVD <- svd(test) *** caught segfault *** address 0x7fe93514d618, cause 'memory not mapped' Traceback: 1: La.svd(x, nu, nv) 2: svd(test) -------------------------------------- Dario Strbenac University of Sydney Camperdown NSW 2050 Australia ______________________________________________ R-devel@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-devel
