Retrieve the last query submitted to CliFlo instead of querying the database again and losing subscription rows.
Details
This function is a back up for when the clifro query has been submitted and the data returned but has not been assigned, or inadvertently deleted. This saves the user resubmitting queries and using more rows from their subscription than needed.
Examples
if (FALSE) { # \dontrun{
# Query CliFlo for wind at Reefton Ews
cf_query(cf_user(), cf_datatype(2, 1, 1, 1), cf_station(), "2012-01-01 00")
# Oops! Forgot to assign it to a variable...
reefton.wind = cf_last_query()
reefton.wind
} # }
