...urring in paste.c. By wrapping the macro's arguments in parentheses, we can ensure that the correct order of evaluation will take place during preprocessing. To illustrate, we can use the == operator which has lower evaluation precedence than the < operator: * With the current macro, imax2(3==4, 1) expands to 0. * After applying this patch, imax2(3==4, 1) expands to 1 as expected. Since I'm still relatively new to the mailing list, I've kept this patch small. I did notice other macros that have this same issue, so I can start sending additional patches if this seems o...

...I copied it to my home folder and changed permissons from root to my personal user and then tried to call R functions from a different language (that has a 'native' function to call any kind of Shared Library on Linux). But to no avail - no matter if I try to call 'help' or 'imax2', I'm always told the function doesn't exist. So my question is basically: whats in there in the libR.so? Can't I call all core R functions (via 'native') with the same arguments as on the R command line? I'm a bit confused now about how to use R as a shared library on...
