unless you've read in your "files" object with something like
read.delim(..., as.is=TRUE), then the content of each column is probably a
factor rather than e.g. numeric or character. Does it work is you say?:

raw <- readCtData(files=files$FileName, path=path, SDS=TRUE, header=TRUE,
n.features=384, feature=4, type=5, position=1, Ct=6,
samples=as.character(files$SampleName))
