split & unsplit Functions in R (2 Examples) | Divide & Reassemble Data | Vector Object into Chunks

R code of this video:

vec ＜- 1:10 # Create example vector
vec # Print example vector

groups ＜- c(rep("A", 3), # Create grouping vector
rep("B", 5),
rep("C", 2))
groups # Print grouping vector

my_split ＜- split(vec, groups) # Apply split function
my_split # Print output

my_unsplit ＜- unsplit(my_split, groups) # Apply unsplit function
my_unsplit # Print output

Interesting video. I have heard of unlist and also nest and unnest (tidyverse I believe). How are those related to these split/unsplit functions? Thanks!
