R code of this video:

x1 = c(5, 1, 4, 9, 1, 2),
x2 = c("A", "Y", "G", "F", "G", "Y"))

y1 = c(3, 3, 4, 1, 2, 9),
y2 = c("a", "x", "a", "x", "a", "x"))

z1 = c(3, 2),
z2 = c("K", "b"))

library("dplyr") # Load dplyr package
library("plyr") # Load plyr package
library("readr") # Load readr package

lapply(read_csv) %＞% # Store all files in list
bind_rows # Combine data sets into one data set

library("purrr")

lapply(read_csv) %＞% # Store all files in list
purrr::reduce(full_join, by = "id") # Full-join data sets into one data set
