I frequently encounter a situation in which I want to remove a
single element of an array. For example, if I am reading in a bunch
of CSV files, I create the list of files to be read with:
LIST <- dir()
However, sometimes I want to exclude one or more files. I can
accomplish this with a second command:
LIST <- LIST[LIST != "filename.to.be.excluded"]
This is cumbersome -- is there some more efficient code to
accomplish this?
Doesn't negative indexing provide this?
