Hello,
I got an error with pcaMethods when using it on a docker image on my server.
when I use it on a simple matrix I got the error :
*** caught illegal operation ***
address 0x7f8b13c0f224, cause 'illegal operand'
Traceback:
1: RnipalsPca(prepres$data, nPcs = nPcs, ...)
2: pcaMethods::pca(t(mat), method = "rnipals", nPCs = 2)
An irrecoverable exception occurred. R is aborting now ...

The important thing to notice is that when I use pcaMethod on the server it works fine but not when I launch it from a docker image.
Thank you in advance
