No, it was type = "l" (the letter 'el'), which is short for "lines" as seen in 
?plot.

Listen on the video:

Start at 2:45,

"type equals line 'l'" is what the presenter says... Clearly it is an "l" (the 
letter el).

Regardless, the official documentation for R is not YouTube videos.  ?plot 
clearly tells you what are valid values for the "type" parameter in plot.
