Select cell values from a multi-layer Raster* object

Use a Raster* object to select cell values from different layers in a multi-layer Raster* object. The object to select values y should have cell values between 1 and nlayers(x). The values of y are rounded.

See extract for extraction of values by cell, point, or otherwise.

Usage
# S4 method for RasterStackBrick,Raster
stackSelect(x, y, recycle=FALSE, type='index', filename='', ...)
Arguments
x

RasterStack or RasterBrick object

y

Raster* object

recycle

Logical. Recursively select values (default = FALSE. Only relevant if y has multiple layers. E.g. if x has 12 layers, and y has 4 layers, the indices of the y layers are used three times.

type

Character. Only relevant when recycle=TRUE. Can be 'index' or 'truefalse'. If it is 'index', the cell values of y should represent layer numbers. If it is 'truefalse' layer numbers are indicated by 0 (not used, NA returned) and 1 (used)

filename

Character. Output filename (optional)

Additional arguments as for writeRaster

Value

Raster* object
