R comments
Comments are for explaining R code, and for making it more readable. Comments are also for preventing execution when testing alternative code. Comments starts with a #. R will ignore anything that starts with # when executing code.
Single line comments
Example using a comment before a line of code:
# This is a comment
"Hello!"> # This is a comment
> “Hello!”
[1] “Hello!”
example using a comment at the end of a line of code:
"Hello!" # This is a comment> “Hello!” # This is a comment
[1] “Hello!”
Multiline Comments
There are no syntax in R for multiline comments. However, we can just insert a # for each line to create multiline comments:
# This is a comment
# in multiline
# more than just one line
"Hello!"> # This is a comment
> # in multiline
> # more than just one line
> “Hello!”
[1] “Hello!”
