Check that the vector of time values is included in the
document covariate table and that it is either a integer-conformable or
a date. If it is a date, the input is converted to an
integer, resulting in the timestep being 1 day, which is often not
desired behavior.
check_timename(document_covariate_table, timename)
| document_covariate_table | Document covariate table used to query for the time column. |
|---|---|
| timename | Column name for the time variable to evaluate. |
An error message is thrown if timename is
not proper, else NULL.
