as.linim: Convert to Pixel Image on Linear Network

Description

Converts various kinds of data to a pixel image on a linear network.

Usage

as.linim(X, …)
  # S3 method for linim
as.linim(X, …)
  # S3 method for default
as.linim(X, L, …)

Arguments

X

Data to be converted to a pixel image on a linear network.

L

Linear network (object of class "linnet").

…

Additional arguments passed to X when X is a function, or arguments passed to as.mask which determine the pixel array geometry.

Value

An image object on a linear network; an object of class "linim".

Details

This function converts the data X into a pixel image on a linear network, an object of class "linim" (see linim).

The argument X may be any of the following:

• a pixel image on a linear network, an object of class "linim".

• a pixel image, an object of class "im".

• any type of data acceptable to as.im, such as a function, numeric value, or window.

First X is converted to a pixel image object Y (object of class "im"). The conversion is performed by as.im using any relevant arguments specified in …. For example the argument eps could be used to change the pixel resolution.

Next Y is converted to a pixel image on a linear network using linim. The argument L determines the linear network. If L is missing or NULL, then X should be an object of class "linim", and L defaults to the linear network on which X is defined.

  f <- function(x,y){ x + y }
  plot(as.linim(f, simplenet))
