Dear Hugo, This is a problem with installing the dependency "ncdf." The installation info on CRAN might help you: http://cran.r-project.org/web/packages/ncdf/INSTALL If that doesn't work, try the ncdf author, whose contact info is on this page: http://cirrus.ucsd.edu/~pierce/ncdf/ Please copy the Bioconductor mailing list (bioconductor at r-project.org) with any follow-up questions. I also recommend that you upgrade to the latest release of R (2.15) before installing, as the version of GWASTools you get when using biocLite() on older R versions is out of date.
