replacementSingle: Replace layers in an object that is of a class derived from...

In via: Virtual Arrays

Replace layers in an object that is of a class derived from 'VirtualArray'.

Description

Single bracket '[' refers to indices and names within the 'VirtualArray'-class object. Use double brackets to replace layers based on their names (in the @stack). Object types of the same kind class can be used to replace values in 'XArray'-class objects. 'SpatRaster'-class objects can be used to replace values in 'RasterArray'-class objects. Classes inheriting from 'sf' can be used with 'SfArray'-class objects.

Usage

## S4 replacement method for signature 'VirtualArray,ANY,ANY,logical'
x[i, j, ...] <- value

## S4 replacement method for signature 'RasterArray,ANY,ANY,SpatRaster'
x[i, j, ...] <- value

## S4 replacement method for signature 'SfcArray,ANY,ANY,sfc'
x[i, j, ...] <- value

## S4 replacement method for signature 'SfArray,ANY,ANY,sf'
x[i, j, ...] <- value

Arguments

x	VirtualArray-class object.
i	subscript of the first dimension(rows) or vector-like subsetting.
j	subscript of the second dimension (columns).
...	subscript of additional dimensions.
value	A same class object as x.

Value

The function has no return value.

Examples

ex <- rastex() 
# replace third element with missing value
ex[3] <- NA
# duplicate first element and make it the second too
ex[2] <- ex[1]
