Dear fellow R and Mac users, I try to promote open source tools for practicals with my students, but I have some issues with the installation of Rattle (great GUI for data mining) on Mac OSX computers (10.6.3 | X11). I'm trying to install it since last week without any success. I need it up and running in a short future that's why I request your help. I followed the official installation procedure: http://datamining.togaware.com/survivor/Install_Macintosh.html1) Download and install GTK+ (25MB) from: http://r.research.att.com/gtk2-framework.dmg 2) Download and install GGobi (5MB) from: http://www.ggobi.org/downloads/ggobi-2.1.8.dmg 3) Installed R2.11(latest) | gfortran 4.2.3 | tcltk-8.5.5-x11 + updated all packages 4) install.packages("rattle", dependencies=c("Depends", "Suggests")) When loading Rattle, it asked for a newer GTK so I installed (on my initiative) GTK+ 2.18.5 framework I found at: http://R.research.att.com/libs/GTK_2.18.5-X11.pkg Alright now I can load Rattle but it doesn't work at all, it keeps returning errors of two different kinds: 1) Tue May 4 08:43:24 COMPUTER.unil.ch R[379] <Error>: CGContextSetFont: invalid context 0x0 Tue May 4 08:43:24 COMPUTER.unil.ch R[379] <Error>: CGContextSetFontSize: invalid context 0x0 .......The list is much longer but always concerns CGContext something 2) ( R:2190): Gtk-WARNING **: Unable to find default local directory monitor type( R:2190): Gtk-WARNING **: Unable to find default local directory monitor type I addressed these to the developer but he's not a Mac user and has no idea of a workaround and suggested me to write this email. Do someone have an idea to solve these issues or can someone try to install it and tell me the outcome? Any help, hint would be much appreciated so we can keep using Mac and open source applications at my university. Kind Regards, MorganUniversité de Lausanne [[alternative HTML version deleted]]
