state_crosswalks {mwlaxeref}

Crosswalk lake identifiers to/from specific states

Description

State specific functions to be used as handy shortcuts. (i.e. you can call a state's function directly rather than specifying local_to_* or *_to_local with the state as an argument. One of these functions exists for all combinations of both states and lake ID columns found in lake_id_xref. For a full list of these functions, see ?all_state_crosswalks

Usage

nhdhr_to_wi(data, from_colname = "nhdhr.id", agency = NULL)

lagos_to_mi(data, from_colname = "lagos.id", agency = NULL, id_field = NULL)

mn_to_mglp(data, from_colname, agency = NULL)

Arguments

data

A data.set with a column containing a lake identifier corresponding to one of the datasets listed above (also see lake_id_xref)

from_colname

Character. The column name in data that lake IDs that are being converted from (e.g. data has a lake ID column that you are trying to convert from – what is the name of that column)

agency

Optional character vector specifying the agency to use for the local ID column. This is helpful if data exist in lake_id_xref for which there are more than one agency in a state that provided data

id_field

Optional character vector specifying the id.field to use for the local ID column. Occasionally states use more than one identifier. This allows explicit choice of which identifier to use.

Value

A data.frame the same as data, but with an additional lake identification column from lake_id_xref

Examples

wi_to_nhdhr(wis_lakes, from_colname = "lake.id")
