Hi all,
I used the SVD function to obtain the Singular values from a big matrix.
I got the errors from R as follows:
20 * caught segfault *
21 address 0x55724e6da770, cause 'memory not mapped'
23 Traceback:
24 1: La.svd(x, nu, nv)
25 2: svd(all, nu = svd_k)
26 An irrecoverable exception occurred. R is aborting now ...
I don't know what went wrong, and it's rare on the Internet. I hope someone can help me solve this problem.
Best
Eric
This is not a bioinformatics question and there's not enough information. Memory not mapped means your process is trying to access memory it doesn't own. This is usually due to a bug however, it's unlikely you've found a bug in the LAPACK SVD (La.svd) so my guess would be that there's some conflict between libraries, i.e. your R code uses a different library than what it's been compiled against.
