How can I turn the filename into a variable when reading multiple csvs into R

Question

I have a bunch of csv files that follow the naming scheme: est2009US.csv.

I am reading them into R as follows:

myFiles <- list.files(path=\"~/Dow

plyr makes this very easy:

library(plyr)
paths <- dir(pattern = "\\.csv$")
names(paths) <- basename(paths)

all <- ldply(paths, read.csv)

Because paths is named, all will automatically get a column containing those names.
