R - Source all files within folder

source_files_from_folder.R

setwd("~/rProgramming")
files.sources = list.files()
sapply(files.sources, source)

Thank you so much :)

excellent idea. just to add on to it. One may not aways be able to change the working directory and in that case, drop the setwd() function. Then, add the path to list.files() as list.files(path="~/rProgramming")

Note - for this to work you also need to have full.names = TRUE within the list.files function so that when you call source in the sapply function it has the path information for each file, which will be required since you didn't change your working directory. I.e. list.files(path="~/rProgramming", full.names = TRUE).
