I get an error when trying to create my RG set.

library(minfi)
baseDir <- "K:/IDATS"
targets <- read.metharray.sheet(baseDir)
RGSet <- read.metharray.exp(base = baseDir, targets = targets, verbose=T)

Error in read.metharray(files, extended = extended, verbose = verbose,  : 
  The following specified files do not exist:

But no files are listed. Anyone else getting this error?

I created a sample sheet (CSV) and put it in a directory containing all my IDAT files. The sample sheet contains a column called Basename, which has the full file path for each IDAT file (minus the "_Grn.idat" and "_Red.idat" suffix).
