get_spat_occ: Get Spatial polygons (SpatVectors) of species based on its distribution (states and biomes) according to Flora e Funga do Brasil

Description

Get Spatial polygons (SpatVectors) of species based on its distribution (states and biomes) according to Flora e Funga do Brasil

Usage

get_spat_occ(
  data,
  species,
  state = TRUE,
  biome = TRUE,
  intersection = TRUE,
  state_vect = NULL,
  state_column = NULL,
  biome_vect = NULL,
  biome_column = NULL,
  verbose = TRUE
)

Value

A list with SpatVectors of states and/or biomes and/or Intersections for each specie.

Arguments

data

(data.frame) the data.frame imported with the load_florabr function.

species

(character) one or more species names (only genus and specific epithet, eg. "Araucaria angustifolia")

state

(logical) get SpatVector of states with occurrence of the species? Default = TRUE

biome

(logical) get SpatVector of biomes with occurrence of the species? Default = TRUE

intersection

(character) get a Spatvector representing the intersection between states and biomes with occurrence of the specie? To use intersection = TRUE, you must define state = TRUE and biome = TRUE". Default = TRUE

state_vect

(SpatVector) a SpatVector of the Brazilian states. By default, it uses the SpatVector provided by geobr::read_state(). It can be another Spatvector, but the structure must be identical to geobr::read_state().

state_column

(character) name of the column in state_vect containing state abbreviations. Only use if biome_vect is not null.

biome_vect

(SpatVector) a SpatVector of the Brazilian biomes. By default, it uses the SpatVector provided by geobr::read_biomes(). It can be another SpatVector, but the structure must be identical to geobr::read_biomes().

biome_column

(character) name of the column in biome_vect containing names of brazilian biomes (in English: "Amazon", "Atlantic_Forest", "Caatinga", "Cerrado", "Pampa" and "Pantanal". Only use if biome_vect is not null.

verbose

(logical) Whether to display species being filtered during function execution. Set to TRUE to enable display, or FALSE to run silently. Default = TRUE.

Examples

library(terra)
data("bf_data") #Load Flora e Funga do Brasil data
spp <- c("Araucaria angustifolia", "Adesmia paranensis") #Example species
#Get states, biomes and intersection states-biomes of species
spp_spt <- get_spat_occ(data = bf_data, species = spp, state = TRUE,
                       biome = TRUE, intersection = TRUE, state_vect = NULL,
                       biome_vect = NULL, verbose = TRUE)


#Plot states of occurrence of Araucaria angustifolia
plot(spp_spt[[1]]$states, main = names(spp_spt)[[1]])
#Plot biomes of occurrence of Araucaria angustifolia
plot(spp_spt[[2]]$biomes, main = names(spp_spt)[[2]])
#Plot intersection between states and biomes of occurrence of
#Araucaria angustifolia
plot(spp_spt[[1]]$states_biomes)
