Check that colnames exist

Check that names passed as arguments for columns containing time stamps and observed quantities exist in col.names.

Usage

check_colnames(col.names, time.name, qty.name = NULL, verbose = FALSE)

Arguments

time.name

character vector of length one Name of the variable containing time stamps for the observations.

qty.name

character vector Name(s) of variable(s) in data containing values observed quantities. If qty.name = NULL, the default, all columns are retained.

verbose

logical Report data columns found. Useful for debugging.

Details

If the column named according to time.name is not in col.names an error is issued. If qty.name = NULL all columns in col.names minus that in time.name. If qty.name is a character vector only names also present in col.names are returned, while if none is present, an error is issued. If only some names in qty.name are discarded a message is issued.
