Usage

df2rast(x, CRS = "+proj=longlat +datum=WGS84", ...)

Arguments

x

data.frame. A data.frame or matrix with species names in columns and sites in rows. The first two columns must provide longitude and latitude, respectively.

CRS

character. Description of the Coordinate Reference System (map projection) in PROJ.4.

...

Value

SpatRaster

dat <- phyloraster::load.data.rosauer()
df2rast(dat$presab, crs = "+proj=longlat +datum=WGS84 +ellps=WGS84
