Append multiple csv files into one file using R

Question

I Have multiple csv files that i have already read into R. Now I want to append all these into one file. I tried few things but getting different errors. Can anyone please h

Answer 1

You can use a combination of lapply(), and do.call().

## cd to the csv directory
setwd("mycsvs")

## read in csvs
csvList <- lapply(list.files("./"), read.csv, stringsAsFactors = F)

## bind them all with do.call
csv <- do.call(rbind, csvList)

You can also use fread() function from the data.table package and rbindlist() instead for a performance boost.
