Data to be converted to a pixel image on a linear network.
Linear network (object of class
Additional arguments passed to
Optional arguments passed to
Optional. Numeric value giving the approximate distance (in coordinate units) between successive sample points along each segment of the network.
This function converts the data
X into a pixel image
on a linear network, an object of class
X may be any of the following:
a function on a linear network, an object of class
a pixel image on a linear network, an object of class
a pixel image, an object of class
any type of data acceptable to
such as a function, numeric value, or window.
X is converted to a pixel image object
(object of class
The conversion is performed by
determine the pixel resolution.
Y is converted to a pixel image on a linear network
linim. The argument
L determines the
linear network. If
L is missing or
X should be an object of class
L defaults to the linear network on which
X is defined.
In addition to converting the
function to a pixel image, the algorithm also generates a fine grid of
sample points evenly spaced along each segment of the network
(with spacing at most
delta coordinate units). The function values
at these sample points are stored in the resulting object as a data frame
linim). This mechanism allows
greater accuracy for some calculations (such as
An image object on a linear network; an object of class
