[R] question

[Lida Zeighami]

I have 682 variables in a data frame , and a function that  I should feed
682 variables in this function one by one and each time save the file as a
special name!
for emaple:
my data frame file includes 682 names :
1  aaa
2  bbb
3  dfdsfg
4 fghh
.

682 fgfhg
and a function like prep(Z, aaa, .....) and each time I should change the
variable name in this function and read the variable from the data frame
and each time I should save the file as a special name such as:

prep1<- prep(z, aaa,...)
prep2<- prep(z, bbb,...)
prep3<- prep(z, dfdsfg,..)
Prep4<- prep(z, fghh,...)

How can I use loop function in R to that?

Thanks
