R only knows about single line comments. There is no multi line comment.
If you wish to comment several lines you will have to prefix each line with #.

Your editor may provide means of prefixing several lines with # by selecting lines and executing some command.
Rstudio provides Ctrl+Shift+C (Windows. Linux) and Cmd+Shift+C (OS X) on selected lines.
And other editors have other shortcuts.
You’ll just have to get used to this.
