Multiple left joins in R

Here is a quick and easy way to perform multiple left joins in R with multiple data frames.

Here are 4 data frames that I would like to join by the column date.

The fastest and easiest way to perform multiple left joins in R is by using reduce function from purrr package and, of course, left_join from dplyr.

If you have to combine only a few data sets, then other solutions may be nested left_join functions from the dplyr package. For more than 3 data frames, that is quite a struggle.
