[R] how to get list of files within a particular local file folder
How you "read all ... files" is up to you, as that depends both on the
type of data contained in the files and on how you plan to use the data.
Most likely the solution will involve using the files.list function and either
lapply or a for loop, and the data will end up stored in a list of data objects.
(If the data are tabular you might use the sapply function to create a single
data table.)
