[R] httr::content without message

[Ben Tupper]

Ahoy!

That's a message generated by the readr::read_table() function (or it's friends).  You can suppress it a number of ways, but this should work as httr::content() will pass through arguments, like col_types = cols(), to the file reader.

junk <- httr::content(r1, col_types = cols())
