[BioC] question about reading data into marray package

[Jean Yee Hwa Yang]

Hi Yanqin,

Assuming you have no header infomration you want to skip, can you try the
following command
strsplit(readLines(fnames[1], n=1), split="\t")

and check if you enter the name of the columns correctly in the argument.

You can also add skip = 0 in the call and see if it works.

Cheers

YH
