Hello R users, I am trying to give the QR decomposition for a large sparse matrix in the format of dgCMatrix. When I run qr function for this matrix, the R session simply stops and exits to the shell. The matrix is of size 108595x108595, and it has 4866885 non-zeros. I did the experiment on windows 7 and linux mint 11 (both 64 bit), and the results are the same.
I have uploaded my data file to http://ifile.it/elf2p6z/A.RData . The file is 10.681 MB and I hope someone could kindly download it. The code to see my problem is: library(Matrix) load("A.RData") B <- qr(A) Best wishes, C6 ______________________________________________ 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.
