I am trying to use the function SAMseq from samr package to analyse the gene expression of my matrix but I get this error message.

> sam_test = SAMseq(RNA_seq_DNAm, vector_DNAm, resp.type = "Quantitative",
genenames = names)

Estimating sequencing depths...
Resampling to get new data matrices...
Error in rankcol(t(xresamp[, , k])) : 
  NA/NaN/Inf in foreign function call (arg 1)
In addition: There were 20 warnings (use warnings() to see them)
Error during wrapup: cannot open the connection

Can someone help me understand what it means? This is a school project I am working on.

Thanks in advance!
