res_national_map {SWMPrExtension}

Reserve National Map

Description

Create a base map for NERRS reserves in ggplot

Usage

res_national_map(
  incl = c("contig", "AK", "HI", "PR"),
  highlight_states = NULL,
  highlight_reserves = NULL,
  agg_county = TRUE
)

Arguments

incl

chr vector to include AK, HI , and PR (case sensitive)

highlight_states

chr vector of state FIPS codes

highlight_reserves

chr vector of 3 letter reserve codes

agg_county

logical, should counties be aggregated to the state-level? Defaults to TRUE

Details

Create a base map of the US with options for including AK, HI, and PR. The user can choose which states and NERRS reserves to highlight. An early 'sp'-based version of this function by Julie Padilla was developed, in part, from a blog post by Bob Rudis. The current sf-based version, by Dave Eslinger, uses an approach from the r-spatial tutorial by Mel Moreno and Mathieu Basille.

Value

Returns a ggplot object
