derive_year_sheet_ind.RdBefore 11/7/2019, both fire perimeters and incident reports displayed two sets of variable, depending on whether the data were recorded before or after 2015. As of 11/7/2019, fire perimeters have been updated so that the variable names are consistent across years now. However, incident reports still presents two different variable names depending on whether the year was before or after 2015. This function looks at which sets of variable names to look at based on whether it's a perimeter or incident report file, which year the file is and whether we are dealing with data before 11//7/2019 changes.
derive_year_sheet_ind(ind_perims, year, pre_pst_split_ind)
| ind_perims | (logical): Boolean indicator. If TRUE, the file is a perimeter file, otherwise it is an incident report. |
|---|---|
| pre_pst_split_ind | (logical): Boolean indicator. If TRUE, then variable names for perimeters change before and after 2015 (as before 11/7/2019 changes), so that the `*_pre15` sheets are used in the Firepred data dictionary for before 2015 and the `*_pst15' for the years afterwards. If FALSE (default since 11/7/2019 changes), the `*_pst15' sheets are used across the years for perimeters. |
| yrs | (numeric): Vector with years which data need to be transformed |
A vector of `pre15` or `pst15` according to which Data Dictionary sheet should be considered.
