plot: 'plot' method for 'BIOMOD.formated.data' object class

In biomod2: Ensemble Platform for Species Distribution Modeling

plot method for BIOMOD.formated.data object class

Description

Plot the spatial distribution of presences, absences and pseudo-absences among the different potential dataset (calibration, validation and evaluation). Available only if coordinates were given to BIOMOD_FormatingData.

Usage

## S4 method for signature 'BIOMOD.formated.data,missing'
plot(
  x,
  calib.lines = NULL,
  plot.type,
  plot.output,
  PA,
  run,
  plot.eval,
  do.plot = TRUE
)

Arguments

x	a BIOMOD.formated.data or BIOMOD.formated.data.PA object. Coordinates must be available to be able to use plot.
calib.lines	(optional, default NULL) an array object returned by get_calib_lines or bm_CrossValidation functions, to explore the distribution of calibration and validation datasets
plot.type	a character, either 'points' (default) or 'raster' (if environmental variables were given as a raster). With plot.type = 'points' occurrences will be represented as points (better when using fine-grained data). With plot.type = 'raster' occurrences will be represented as a raster (better when using coarse-grained data)
plot.output	a character, either 'facet' (default) or 'list'. plot.output determines whether plots are returned as a single facet with all plots or a list of individual plots (better when there are numerous graphics)
PA	(optional, default 'all') If x is a BIOMOD.formated.data.PA object, a vector containing pseudo-absence set to be represented
run	(optional, default 'all') If calib.lines provided, a vector containing repetition set to be represented
plot.eval	(optional, default TRUE) A logical defining whether evaluation data should be added to the plot or not
do.plot	(optional, default TRUE) A logical defining whether the plot is to be rendered or not

Value

a list with the data used to generate the plot and a ggplot2 object

Examples

library(terra)

# Load species occurrences (6 species available)
data(DataSpecies)
head(DataSpecies)

# Select the name of the studied species
myRespName <- 'GuloGulo'

# Get corresponding presence/absence data
myResp <- as.numeric(DataSpecies[, myRespName])

# Get corresponding XY coordinates
myRespXY <- DataSpecies[, c('X_WGS84', 'Y_WGS84')]

# Load environmental variables extracted from BIOCLIM (bio_3, bio_4, bio_7, bio_11 & bio_12)
data(bioclim_current)
myExpl <- terra::rast(bioclim_current)



## ----------------------------------------------------------------------- #
# Format Data with true absences
myBiomodData <- BIOMOD_FormatingData(resp.var = myResp,
                                     expl.var = myExpl,
                                     resp.xy = myRespXY,
                                     resp.name = myRespName)
myBiomodData
plot(myBiomodData)
