[R] Cannot install iWidgetsRGtk

[Paul Smith]

Dear All

I am trying to install iWidgetsRGtk (on a Linux machine), but getting
the following error:

> install.packages("iWidgetsRGtk",repos="http://www.math.csi.cuny.edu/pmg")
Warning in download.packages(unique(pkgs), destdir = tmpd, available =
available,  :
         no package 'iWidgetsRGtk' at the repositories
>

Any ideas?

Thanks in advance,

Paul
