Dear all I have a big matrix of standardized values (dimensions 285x5829) and R fails to calculate the principal components using prcomp() with the following error message:
pc <- prcomp(my.matrix) Error in La.svd(x, nu, nv, method) : error code 1 from Lapack routine dgesdd Is the matrix too big? I'm using R-1.8.1 under Unix (Solaris8) and Linux(Suse 8.2). I tried to perform a principal component analysis using a huge matrix with the dimensions 1000x10000 and it worked without an error message. test <- matrix(rnorm(10000000), ncol=1000, nrow=10000) pc <- prcomp(test) Any hints are welcome. Many thanks in advance and best regards, Carlo ****************************************************** Carlo Casty Climatology and Meteorology Phone: +41 (0)31 6318545 Institute of Geography Fax: +41 (0)31 6318511 University of Bern e-mail:[EMAIL PROTECTED] Hallerstr. 12 www.giub.unibe.ch/~casty 3012 Bern/SWITZERLAND ______________________________________________ [EMAIL PROTECTED] mailing list https://www.stat.math.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide! http://www.R-project.org/posting-guide.html
