[BioC] Bug in marrayInput for Windows

[michael watson (IAH-C)]

Hi

There is a bug in read.GenePix in marrayInput for Windows.

The problem comes when I set path=NULL because I have the full path to my file in fnames.  The offending line is:

	y <- readLines(file.path(path, fnames[1]), n=100)

If path=NULL and fnames[1]="C:\\myfile.gpr", then file.path() returns something odd:

	> file.path(NULL,"C:\\myfile.gpr")
	[1] "/C:\\myfile.gpr"

Clearly this is not a valid Windows resource lopcator!

A quick fix, I guess, would be:

	if(is.null(path)) 
		y <- readLines(file.path(fnames[1]), n=100)
	else y <- readLines(file.path(path, fnames[1]), n=100)

Cheers
