Dear all,

While trying to use "xps" for my exon arrays, I face a problem during install.

I have installed the latest stable version of R, bioconductor and Root on my computer (running on windows 7, 64bits).

I have used the following command to install the xps package:

source("http://bioconductor.org/biocLite.R")
biocLite("xps")

However, it failed and returned the following error:

***

BioC_mirror: http://bioconductor.org
Using Bioconductor version 2.14 (BiocInstaller 1.14.2), R version
  3.1.1.
Installing package(s) 'xps'

   package ‘xps’ is available as a source package but not as a binary

Warning message:
package ‘xps’ is not available (for R version 3.1.1)

***

Similar issue has been reported 20months ago ( https://support.bioconductor.org/p/50292/#61688), and it turned out that xps package was not compatible with windows 7 at that time.

Does anyone know whether xps package can be run on windows (windows 7) now? 

All the best,

Alexandre

Dear Alexandre,

Before you install xps you need to install the ROOT framework first. For Windows 7 you need to install a version of ROOT compiled with MinGW. You can download this file from:
https://docs.google.com/file/d/0B0qZ3XBoK1ubVzl5MHBEaWxQdW8/edit

If there may be a problem (which until now has not been the case) then I could send you the file, however it has a size of 35 MB.

Please read the README file how to install ROOT and xps for Windows.

Best regards,
Christian
