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):
> `56Fe2` <- 1:10 # assign a value
> `56Fe2` * 3 # do an operation on it
[1] 3 6 9 12 15 18 21 24 27 30
> get('56Fe2') # get the object; notice the regular quotes in this case,
[1] 1 2 3 4 5 6 7 8 9 10
> ls() # list out the objects in my global environment (its there)
[1] "56Fe2" "allComm" "colnames"
"comm"
[5] "commMap" "createVirtualQuad" "data" "DF"
