I'm having problems using RPy, on Mac 0SX(10.4) via Fink to generate
plots.
I installed Python2.4 and RPy, both via Fink (& both from source).
Prior to starting python, I:
1) started XWindows (specifically: launched the xterm application)
2) setenv DISPLAY ':0.0' (I'm using tcsh)
RPy seems to work ok for non-graphics.
RPy works *up to a point* with graphics, e.g.:
r.plot(1)
generates the appropriate plot, but as son as I move the window, I
get this error:
>>> Error during wrapup: C stack usage is too close to the limit
*** caught bus error ***
address 0x1f, cause 'non-existent physical address'
Possible actions:
1: abort (with core dump)
2: normal R exit
3: exit R without saving workspace
4: exit R saving workspace
Selection:
and the python interpreter hangs.
X11 seems to be stable *except* with RPy
I would really rather not use X11 at all. Can I get RPy to generate
graphics with the Macintosh native ("Quartz") engine? R binaries for
Macintosh do that out-of-the-box (I got mine from http://rh-
mirror.linux.iastate.edu/CRAN/)
Fink, of course, installs its own copy of R (in /sw/bin) which
probably knows nothing about Quartz.
Quartz graphics from RPy is important to me. >50% of my reason for
installing RPy was a need to export graphics from Python / matplotlib
in a vector-graphics format such as PDF.
Several simpler approaches failed, & I know if I can get screen-
graphics via Quartz, saving as PDF should be trivial.
