Remove continents from area dataframe.

Reference a list of continental areas to remove them from the dataframe output by SSARP::find_areas().

Usage

remove_continents(occs)

Arguments

occs

The dataframe that is returned by SSARP::find_areas(). I do not recommend using a custom dataframe for this function because it references areas given by the area database used in SSARP::find_areas(). If you must use a custom dataframe, please ensure that the landmass areas are in the 9th column of the dataframe.

Value

A dataframe of the species name, island name, and island area (without continents)

Examples

# The GBIF key for the Anolis genus is 8782549
#  Obtained with: key <- get_key(query = "Anolis", rank = "genus")
key <- 8782549
# Read in example dataset obtained through:
#  dat <- get_data(key = key, limit = 100)
dat <- read.csv(system.file("extdata",
                            "SSARP_Example_Dat.csv",
                            package = "SSARP"))
occs <- find_land(occurrences = dat)
areas <- find_areas(occs = occs)
#> ℹ Recording island names...
#> ℹ Assembling island dictionary...
#> ℹ Adding areas to final dataframe...
new_areas <- remove_continents(areas)
