loadShape {actel}

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.
