Got exactly the same issue as you.
did you sort it out?
in addition to your error I had this error at the IMA.methy450PP stage I got
this:
Warning message:
In if (snpfilter != FALSE) { :
the condition has length > 1 and only the first element will be used

Hello
i need some precision about nipals in the chemometrics package in R .
When i use nipals in chemometrics i obtain T and P matrix.
I really don't understand what to do with these two matrix to obtain
