how to extract columns from csv using a list of name

Question

[baijiangshan9726]

I have a list of name, c <- ("a","c","e"), which is a subset of the column names from a matrix(let's say the column names are "a","b","c","d","e","f"). Now I want to use the list of name to extract corresponding columns from this matrix, how should I do this in R.

I would recommend looking up the select function of the dplyr package, convert your matrix to a data frame first. There are many ways to do this, type your question in to google.
