how to source all fies from a directory in r

To source all files from a directory in R, you can follow these steps:

1. Set the working directory to the directory containing the files using the setwd() function: setwd("path_to_directory")

2. Use the list.files() function to list all the files in the directory: file_list <- list.files()

3. Create a for loop to source each file: for (file in file_list) { source(file) }
