Hello, I am trying to use the lumiR function from the lumi package to read in a BeadStudio output file, but I keep getting the following error: > input_file = "sample_probe_profile.txt"; > data = lumiR(input_file, lib = 'lumiHumanV1') Error in mget(targetID, get(paste(lib, "TARGETID2NUID", sep = ""), mode = "environment"),  :   invalid first argument In addition: Warning message: In formatC(as.numeric(id), width = width, flag = "0", format = "d") :   NAs introduced by coercion I have recently used this exact command to successfully process a different dataset. I compared the two input files, and they look more or less the same to me (one dataset includes more types of columns, but otherwise they appear the same). Thus I am at a loss to discover why one file works and the other doesn't. I have searched the mailing list archives and google, but cannot find anyone with the same error for lumiR. I would greatly appreciate any suggestions for overcoming this error. Best regards, Kristen Dang [[alternative HTML version deleted]]
