Hello,
I have 2700 text files in a folder and need to apply
the same program/procedure to each individually. I'm
trying to find how to code something like:
For each file in <Folder> do {<Procedure>}
is there an easy way to do this? other suggestions?
I have tried to list all the files names in a vector
e.g.
>listfiles[1:10,1]
1 H:/Rtest/AXP.txt
2 H:/Rtest/BA.txt
3 H:/Rtest/C.txt
4 H:/Rtest/CAT.txt
5 H:/Rtest/DD.txt
6 H:/Rtest/DIS.txt
7 H:/Rtest/EK.txt
8 H:/Rtest/GE.txt
9 H:/Rtest/GM.txt
10 H:/Rtest/HD.txt
but R doesn't like statements of type
>read.table(file=listfiles[1,1])
since 'file' must be a character string or
connection...
Any thoughts?
Many thanks in advance,
Ron Piccinini.
