Default Error in read.table, package("gage")

Hi,
I am trying to establish gage protocol by Weijun Luo. I get the following error when I want to load the demo data:

> filename=system.file("exdata/gse16873.demo", package = "gage")
> demo.data=readExpData(filename, row.names=1)
Error in read.table(file = file, header = header, sep = sep, quote = quote, :
no lines available in input
In addition: Warning message:
In file(file, "rt") :
file("") only supports open = "w+" and open = "w+b": using the former

Any help?

Parham,
You had an typo in the following line, the data directory should be extdata/ not exdata/
filename=system.file("extdata/gse16873.demo", package = "gage")

It works for me:
> filename=system.file("extdata/gse16873.demo", package = "gage")
> demo.data=readExpData(filename, row.names=1)
> str(demo.data)
'data.frame': 100 obs. of 12 variables:
$ HN_1 : num 6.77 6.34 6.59 6.82 7.36 ...
$ DCIS_1: num 6.46 6.76 6.79 6.59 7.31 ...
$ HN_2 : num 6.92 7.18 6.74 6.51 7.39 ...
$ DCIS_2: num 6.77 6.84 6.77 6.41 7.33 ...

Yes bigmw, I figured later. Thanks though.
Are you good at gage? I have another thread asking a problem.
