prcomp: error code 1 from Lapack routine dgesdd
...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
