displayNiche | R Documentation |
This function extracts worldclim data for a given spatial object and displays the worldclim data for the spatial points.
displayNiche( data, lon = "x", lat = "y", name = "worldclim", res = 10, variables = c("tmin", "tmax", "prec"), tres = "year", path = "", extent = NA, hist = FALSE, map = FALSE, download = TRUE )
data |
raster layer or stack of the presence of one or multiple species, also takes a list |
lon |
Name of longitude column in data file, default x |
lat |
Name of latitude column in data file, default y |
name |
specifying which environmental data to use, currently only worldclim is supported. |
res |
specifying the desired spatial resolution. Valid resolutions are 0.5, 2.5, 5, 10 (minutes of a degree). |
variables |
specifying which variables to get, can be tmin, tmax and/or prec or bio. |
tres |
specifying the desired temporal resolution. One of year, month, quarter. |
path |
Character. Path name indicating where to store the data. Default is the current working directory. |
extent |
specify extent of area considered |
hist |
logical. specify if a histogram should be added to the plot. |
map |
logical. specify if a map should be added to the plot. |
download |
logical. download worldclim data or not. If download=FALSE the bioclimatic variables need to be provided with the data that is inserted into the function and bioclimatic variables need to be named accordingly (bio1, bio2, ...). |
