Dear List, I have just got a laptop with win 7 64 bit installed on it. I installed R and quite a few packages I use. When I try to start BiodiversityR the library loads without any problems but when starting the GUI it gives me the following error message: Sourced: BiodiversityGUI.R Error : .onAttach failed in attachNamespace() for 'Rcmdr', details: call: get(Menus[m, 5]) error: object 'chisquareDistributionPlot' not found Error in BiodiversityRGUI() : needs Rcmdr Surprisingly enough Rcmdr loads without any problems. I am using R 2.13.0 64 bit. Any thoughts? Thanks, Gabor -- Pozsgai G?bor www.coleoptera.hu www.photogabor.com
