Challenge 3 describes a "csv" file delimited by the tab character. By definition, a csv file is comma-delimited. I'd like to propose replacing references to csv with table/tabular to remove this inconsistency

??read table throws an error due to the space between "read" and "table" (Error: unexpected symbol in "??read table"). This statement should be revised.
UPDATE code as written does not produce error.

Hi @jcoliver, thanks for the feedback. You're right, ??read table gives an error, but ??"read table" should work. Do I need to escape the double-quotes, or did you just overlook them when checking?

Yar! I totally overlooked the double-quotes. But, when I run `??"read table", no results are returned. Should there be?

I've just tested it on a completely fresh install of R (current release - 3.6.1) and it comes up with base::base-defunct and utils::read.table - that's the same whether I'm using command line, the R app, or RStudio (on MacOS Mojave). Are you testing through RStudio? I know that for at least one of the recent RStudio releases, the "??" function didn't work at all.

I can confirm this is an RStudio problem (https://stackoverflow.com/questions/57623417/double-question-mark-help-search-not-working-in-rstudio-and-rstudio-only).
Thanks for testing this out, @marklcrowe!
