Hi,
I am trying to modify the devX11.c source in the directory R-2.4.1/
src/modules/X11.
Under OS X 10.4.9 running the R gui (R version 2.4.1) on a
Powerbook, i type this and get the subsequent error.
> dyn.unload("/Library/Frameworks/R.framework/Resources/modules/ppc/
R_X11.so")
Error in dyn.unload(x) : dynamic/shared library '/Library/Frameworks/
R.framework/Resources/modules/ppc/R_X11.so' was not loaded
Yet, when i type the same line in terminal R, it works.
Q1: How do find out what dlls have been loaded?
Q2. In terminal R (with X11.app not running) , i unloaded R_X11.so
(as above), which worked. I then loaded my own R_X11_b.so (displaying
warning messages).
I then unloaded this one and following occurred
a) I ran X11() - it still ran, displaying my warnings - but it
shouldn't have run since i unloaded all the R_X11.so (mine and R's)
b)upon modifying the warning messages (again) and reloading, the
warning messages don't reflect those of the new compiled devX11.c
e.g in R_init_R_X11, which runs upon the "so" file being loaded, did
not display the modified warning messages - it showed the old ones
(in (a))
I would appreciate any help on this matter
