I have a dataframe with three variables: ID, group, and nominated_ID. I want to know the group开发者_StackOverflow社区 that nominated_ID belongs in.
In short, the situation is this: I have been trying to compile a C code with option gcc -O2 -ftree-vectorize -msse4 -ftree-vectorizer-verbose=10 -march=core2 -g -c. For certain nested for-loop constru

This is very closely related to this other question, but that question wanted to avoid sub2ind because of performance concerns. I am more concerned about the \"unelegance\" of using sub2ind.
It's difficult to tell what is being asked here. This question is ambiguous, vague, incomplete, overly broad, or rhetorical andcannot be reasonably answered in its current form. For help clari
