r - how to read one file from multiple folders?

Question

In R, if I have one folder called "main" which has 10 subfolders called from A,B,C...J, each sub folder has a .txt file, sub folder A has a 1.txt, subfolder B has a 2.txt, how can I read all this file without typing the name of each file ?

I used this code

data.path="C:/file/path/main"
files=list.files(path=data.path, recursive =T, pattern = "*.txt")
read_file= read.delim(files,header = TRUE, sep = "")

and this message appeared : No such file or directory

Answer 1

library(readr)

data.path <- "C:/file/path/main"
files <- list.files(path = data.path, pattern = "*.txt", full.names = TRUE)
Then you can use `lapply` function to apply `read_csv` to your files:

data <- lapply(files, read_csv)

You can also use `read_csv` in order to read text files.
