search for: isvectoratomic

Looking at the source code of sort() -- for some speedup considerations -- I found that we currently use isVector() for testing the validity of x in sort(x) whereas I think we should use isVectorAtomic(), actually for S-plus compatibility additionally allowing NULL. Hence I'd propose to replace the test if (!isVector(CAR(args))) errorcall(call, "only vectors can be sorted"); by if(CAR(args) == R_NilValue) return R_NilValue; if(!isVectorAtomic(CAR(args))) errorcall(c...
