This happens when you install a package from the tarball. The source is unpacked into a temporary directory which is then deleted. Try unpacking the source tarball yourself, and then installing from the unpacked directory, e.g. tar xfvz VBMix_0.2.17.tar.gz R CMD INSTALL VBMix Martyn > Thanks by advance, > Pierrick > > ______________________________________________ > R-devel@r-project.org mailing list > https://stat.ethz.ch/mailman/listinfo/r-devel ----------------------------------------------------------------------- This message and its attachments are strictly confidenti...{{dropped:8}} ______________________________________________ R-devel@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-devel
