Hello to everyone. I have been reading multiple threads on the subject and I have been following every suggestion given so far without success. I have a 32 bit Windows 7 machine with currently installed R3.1.0, Bioconductor version 2.14 (BiocInstaller 1.14.2) and Root 5.34.18 installed in C:\root\bin\. Finally, I got the Microsoft Visual Studio 12.0 (free version)-required for Root. I have successfully installed the xps package but when I am trying to load the library, I get the following error: Error in inDL(x, as.logical(local), as.logical(now), ...) : unable to load shared object 'C:/Users/Owner/Documents/R/win- library/3.1/xps/libs/i386/xps.dll': LoadLibrary failure: The specified module could not be found. Error: package or namespace load failed for ‘xps’ Any help would be greately appreciated, Loukia Loukia N.

In fact, xps will not build with the root built with Visual Studio, you have to get the root built for MinGW, see the xps README (http://www.bioconductor.org/ packages/release/bioc/readmes/xps/README): " Ib. Install ROOT for Windows XP, Vista and Windows 7 For Windows users it is important to install a binary version of ROOT compiled with MinGW, currently version root_v5.32.03, from: to be announced; currently, please contact me to get 'root-mingw-O2.7z' of size 37MB It is recommended to install ROOT in the default directory C:\root. Furthermore, it is necessary to set the environment variable ROOTSYS: under Windows you can use `System' in the control panel or the properties of `My Computer' (under the `Advanced' tab). Simply add: ROOTSYS=C:\root\bin (or: ROOTSYS=C:\root if you add %ROOTSYS%\bin to PATH) " Where "me" refers to the xps maintainer, CC'd here.

Dear Loukia, As Dan kindly mentioned you need to get root built with MingGW. You can download the MinGW binary from: https://docs.google.com/file/d/0B0qZ3XBoK1ubVzl5MHBEaWxQdW8/edit see also: https://stat.ethz.ch/pipermail/bioconductor/2014-March/058387.html Best regards, Christian On 5/22/14 11:52 PM, Lili, Loukia wrote: > Hello to everyone. > > I have been reading multiple threads on the subject and I have been following every suggestion given so far without success. > > I have a 32 bit Windows 7 machine with currently installed R3.1.0, Bioconductor version 2.14 (BiocInstaller 1.14.2) and Root 5.34.18 installed in C:\root\bin\.
