[R] Looping through R objects

[Vivek Ayer]

That just creates one object and doesn't contain any $ subobjects in
it. Here's what I did to figure it out (It's complicated):

for(i in c(1:13))
assign(paste("bc",i,sep=""),read.csv(paste(i,".csv",sep=""),sep="",header=TRUE))

in shorthand: for {assign(paste,read(paste))}

This creates individual objects for each csv file and allows me to
have $ subjects, e.g., bc1$foo.

Thanks again,
Vivek
