Put the code in a text file in your working directory.

Within R,


or whatever you called it. If someone suggests a command you don't

If you are copying and pasting very long commands, you may overflow
the clipboard buffer or R terminal buffer, and your code won't be
pasted correctly. Several of us have suggested that's what might be
happening and offered alternatives.
