| defineUnitCol {GenEst} | R Documentation |
Auto-parsing to find the name of the unit column (unitCol)
Description
If a unit column is not explicitly defined by user in the arg list to
estM or estg, then defineUnitCol parses the CO, DWP,
and SS files to extract the unit column if possible.
Criteria that a column must meet to be a unit column are that it is found
in both data_CO and data_DWP, all units in data_CO must
also be included among units in data_DWP, all units in both
data_CO and data_DWP must be included among the column names
in data_SS. If data_DWP = NULL, then the unit column must be
included in data_CO and all its units must be included among the
column names of data_SS.
Usage
defineUnitCol(data_CO, data_SS = NULL, data_DWP = NULL)
Arguments
data_CO |
carcass observation data (data frame) |
data_SS |
search schedule data (data frame) |
data_DWP |
density-weighted proportion data (data frame) |
Value
name of unit column (unitCol), if a unique unit column can be
identified. If no unit column is present or there is more than one unit
column, defineUnitCol stops with an error.
