comment
A comment is a line of code, or segment of code, that is ignored by R.
Programmers use comments to add notes and other documentation to their code.
You can create a comment in R by adding a hashtag #
before the text that you want R to ignore.
Example
rm(list=ls()) # Clear the workspace (this is a comment)
# Read in my data (this is also a comment)
df <- read.csv("my_data.csv")
