Select and import dataframes into a list from the global environment

Question

I would like to select and import ca. 30 dataframes from my global environment into a list. All my dataframes end with ".AM", therefore should be very easy to import them but I am still quite new to R.

I tried:

mylist <- list(pattern = "*.AM")

but it doesn't work.

This is a [duplicate](http://stackoverflow.com/questions/17499013/how-do-i-make-a-list-of-data-frames). See the answers here as well. — lmo, Jul 08 '16 at 11:52

We can use mget to return the datasets in a list.

mget(ls(pattern =  "*.AM"))

you are looking for

mylist <- ls(pattern = ".AM")

which returns mylist as a vector of the matching object names

try to set the working directory to wherever the files are saved

setwd("C:\\user\\files")

then create a list of the .AM dataframes

mylist = list.files(pattern="*.AM")

I guess that should work?
