I've got stuck when trying to replace values in a vector by selecting
replacements from a replacement table. I'm trying to use only base
functions. Here's a dummy example:
(x - rep(letters,2))
[1] a b c d e f g h i j k l m n o p
q r s t u v
[23] w x y z a b c d e f g h i j k l
m n o p q

Try match(). I think it provides hlookup() functionality.

Dear all
Is there a simpler method to achieve the following: When I obtain an

I have a 'character' vector containing mixed formats (thanks Excel!)

To avoid such mistakes it would help to first store your data in a vector.
