Re: [R] loop through files and create object

Consider using a 'list' to hold the matrices: dataList <- lapply(1:47, function(num){ read.csv(paste('country', num, '.raw', sep=''), header=TRUE) } You can then access your data like: dataList[[23]] for the 23rd file read in. On Tue, Jul 20, 2010 at 7:52 AM, Daniel Caro wrote: > Hi R us
