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

You can create the object from lapply first.

Lapply <- lapply(myFiles, read.csv, header=TRUE))
names(Lapply) <- myFiles
for(i in myFiles) 
    Lapply[[i]]$Source = i
do.call(rbind, Lapply)
