issue merging multiple csv files into a single dataframe in R

Question

I have seen lots of answers for this but when I have tried them, my dataframe is empty - "attempt to set an attribute on NULL"

setwd("*my path*")
library(ggplot2)
library(class)
set.seed(3060)

label<-11
index<-000

for(label in 11:37)
{
  for(index in 000:419){

    nameOfFile <- paste(label, index, "features.csv", sep = "_")

    files <- list.files(path=getwd(), pattern=nameOfFile)

    training <- do.call(rbind, lapply(files, read.csv, header=FALSE))


  }    
}

All of my csv files are of the same format - one row and 22 columns.

Answer 1

might need to mess with this code a bit but you shouldn't need to loop to read files.

library(tidyverse)

do.call(bind_rows,
        lapply(paste0("data_location/", list.files("data_location/")), read_csv))
