DEPRECATED
Description
Please use shapeToRaster instead.
Usage
loadShape(
shape,
size,
spatial = "spatial.csv",
coord.x = NULL,
coord.y = NULL,
buffer = NULL,
type = c("land", "water")
)
Arguments
shape |
The path to a shapefile containing land polygons of the study area. |
size |
The pixel size, in metres. |
spatial |
Either a character string specifying the path to a spatial.csv file or a spatial data frame. This argument is not mandatory, but can be used to perform an early check of the shape file's compatibility with the study stations and release sites. |
coord.x , coord.y |
The names of the columns containing the x and y positions of the stations in the spatial.csv file. these coordinates MUST BE in the same coordinate system as the shape file. |
buffer |
Artificially expand the map edges. Can be a single value (applied to all edges) or four values (xmin, xmax, ymin, ymax). The unit of the buffer depends on the shape file's coordinate system. |
type |
The type of shapefile being loaded. One of "land", if the shapefile's polygons represent landmasses, or "water", if the shapefile's polygons represent water bodies. |
Value
A raster object.
