Read multiple CSV files into a single dataframe

multiple_csv.R

create_big_data_from_csv_dir <- function(directory, ids) {
  # locate the files
  files <- list.files(directory, full.names=T)[ids]
  
  # read the files into a list of data.frames
  data.list <- lapply(files, read.csv)
  
  # concatenate into one big data.frame
  data.cat <- do.call(rbind, data.list)
  
  # aggregate
  # data.agg <- aggregate(value ~ index, data.cat, mean)
}

@SimonStolz that's pretty cool :) Thank you! 👍
