Arguments

cnvs_response

An object returned by a cnvs() call.

.token

Authentication token. Defaults to cnvs_token().

.send_headers

Details

Note that these are not always defined. E.g. if the first page was queried (the default), then there are no first and previous pages defined. If there is no next page, then there is no next page defined, etc.

If the requested page does not exist, an error is thrown.

x2 <- cnvs_next(x)
} # }
