assign()
The only people who should use the assign function are those who fully
understand why you should never use the assign function.

It all depends on what you want to do with the object. If you use
back quotes, you can have the object named anything you want (I think
this was pointed out in a previous reply):

Don't think you can have numerics as the first characters in a variable name.
R ninjas can confirm, but I think you will be able to have numerics after an
initial alpha character, e.g.
Fe56 is ok, but 56Fe is not ok.
Also, check out "gsub". This is a really powerful string editing tool.
The only people who should use the assign function are those who fully
understand why you should never use the assign function.
If you tell us where the string is coming from and what you are trying to
accomplish, then maybe we can help you accomplish it in a better way.

Hi
I have a string "56 Fe [1]" that I would like to use as a variable name by using
"assign" however I think the spaces and brackets might be causing R some trouble.
Not really;
R> assign( "56 Fe [1]", 10 )
R> `56 Fe [1]`
[1] 10
How can I change t
