I import a CSV file like this: Name, Sex, Age, ... , ... Tom, M, 12, ... ,... Bob, M, 13, Lily, F, 11, Jack, M, 14, Micheal, M, 10, .. It become a list and I call it datalist. Then I want only extract the Name and Age for each child in the list. I did some thing like: ColumPos = Map[#[[2]] &, Map[Position[datalist, #] &, {"Name", "Age"}], {2}] Map[Extract[#, ColumPos] &, datalist] Yes, it works. But the code are bit complicated. Any one has any idea to get it done in a more efficient way?
