Cannot install package

[njtierney]

Hi there,

Following the directions on the ReadMe, I could not install RGTk2.

I have a mac, so I went to http://r.research.att.com/, downloaded RGTk2, installed it. Then I tried to install it into R from source

install.packages('RGtk2', type = "source")

And got the following error:

Installing package into ‘/Users/tierneyn/Library/R/3.1/library’

I was just wondering if you could provide any advice on how I can install your package?

Perhaps, you have to install 'GTK' in Mac via the following line.

brew install gtk+
