[BioC] xps- not being able to load it

[Steve Lianoglou]

Hi,

The problem is that you do not have the required libraries installed
on your system.

If you look at the xps package page:
http://www.bioconductor.org/packages/2.11/bioc/html/xps.html

You will see that:
(1) The "System Requirements" lists "root_..."; and
(2) It tells you to read the README included in the package, which you
can find here:
http://www.bioconductor.org/packages/2.11/bioc/readmes/xps/README

Where it says:

"""... the prior installation of ROOT is a prerequisite for the usage
of this package. ROOT can be downloaded from http://root.cern.ch."""

Also, your error message points you to what the problem might be, for instance:

[/snip]

You can see that the package expects `root` to be installed in /usr/local/

The instructions on how to install `root` there are in that README I
linked to previously.
