why did i think that i just needed need a couple of #defines in order to use the #RStats Matrix package's #cholmod headers https://github.com/cran/Matrix/blob/master/inst/include/Matrix/cholmod.h (and Matrix.so) to compile the bcftools PGS plugin https://github.com/freeseek/score/blob/master/pgs.c ? It worked on gcc, but clang (with defaults) was much less forgiving :D
#RStats gurus : is their a #RStats package that just provides cholmod and nothing else ?
