There a possibly a cleaner way to change initialization options, using get_initoptions() and set_initoptions() http://rpy.sourceforge.net/rpy2/doc-dev/html/rinterface.html#initialization For example: import rpy2.rinterface as ri options = ri.get_initoptions() options += ("--arch=x86_64", ) ri.set_initoptions(options) import rpy2.robjects as ro > However, after recompiling and installing, rpy2 starts R, but I get the > message: > > WARNING: unknown option --arch=x86_64 > > As far as I can tell from the R help page this is a valid option. > > So it seems that the problem lies in starting the R process with the 64 > bit version Starting an embedded R (through Rf_initialize_R vi rinterface.initr()) is done from a C library (therefore the choice for an architecture must have already been made at that point). The issue might be on the python side: are you using a 32 bit or a 64 bit python ?
