R help - Dec 2010 - creating a list of dataframes

I am iterating through multiple files and storing dataframes in a list. I
want to perform calculations on these dataframes. How would I go about doing
this?
I do:
num_files<- list.files()
list = c()
for(x in num_files)
{
frame = read.table(x)
list = c(list, assign(paste("frame",x),frame))
}

For each row in each data frame I want to calculate the correlation between
the rows. How do I do this?

1) You have redefined the command list which creates lists - not a great
idea.

2) See lapply; for example. Try something like:

list.of.df <- lapply(list.of.filenames,read.csv)
list.of.results <- lapply(list.of.df,your.application.function)

David
