Hi all,

I have a R code with quite a few lines.  For instance

AA <- read.csv(C:\\AA.txt)
AA.diff <- diff(log(AA))
.....
....

Now I want to re-define the code with different object, like BB,
CC......ZZ(the codes are the same). Thus, I was wondering whether their is
an efficient way or automatic way to replace and generate new objects rather
than using "find and replace" function in txt/word manually....?

Appreciate for any help.

Many thanks
mam
