[BioC] Error in marrayTools - gpTools()

[michael watson (IAH-C)]

Hi

I am having trouble with gpTools() function of marrayTools package.  I am using marrayTools 1.2.2 and marrayClasses 1.2.1, on Windows XP, R version 1.7.1.

Following the instructions, I change directory to one that has 4 .gpr files in it (plus some other files, but they are .RData and .RHistory files, so shouldn't matter.

I then load library(marrayTools)

Then execute:

>data <- gpTools()

I get the error:

Error in gsub(pattern, replacement, x, ignore.case, extended) :
	invalid argument

Can anyone help?  It's a shame I couldn't get it to work as it's such a great little function!

Thanks
Mick
