[R] renaming an object

Say I have a file called exp.batch which contains 2 cols
The first col contains names of R objects the user would like to use.
The second col contains the file names which will be read in using
read.table
i.e. exp.batch may look like this.....

name1	complex/filename/path1.txt
name2   complex/filename/path2.txt
name3	complex/filename/path3.txt
name4   complex/filename/path4.txt

I want to have a function which will read in the files and make them into
the objects named in the 1st column - automatically (by just providing
exp.batch)

for(i in 1:nrow(exp.batch)){
tmp<-read.table(as.name(exp.batch[i,2]),...)
##
##But now I really want tmp to be   as.name(exp.batch[i,1])???
## so that I can call the data from complex/filename/path1.txt
## by typing name1 
}
In  the end I should have objects name1, name2, name3, name4
which are the names stored in the 1st column of exp.batch

The basic idea is having to avoid typing out all this!

name1<-read.table("file1",....)
name2<-read.table("file2",....)
..
..
..
nameN<-read.table("fileN",...)

Does anyone have any suggestions?

Thanks in advance,

Natalie
