sampleKernelFunction {mmand}

Sampling and plotting kernels

Description

These functions can be used to sample and plot kernel profiles.

Usage

sampleKernelFunction(kernel, values)

## S3 method for class 'kernelArray'
plot(x, y, axis = 1, lwd = 2, col = "red", ...)

## S3 method for class 'kernelFunction'
plot(x, y, xlim = c(-2, 2), lwd = 2,
  col = "red", ...)

Arguments

kernel

A kernel function object.

values

A vector of values to sample the function at. These are in units of pixels, with zero representing the centre of the kernel.

x

A kernel object of the appropriate class.

y

Ignored.

axis

The axis to profile along.

lwd

The line width to use for the kernel profile.

col

The line colour to use for the kernel profile.

...

Additional plot parameters.

xlim

The limits of the range used to profile the kernel.

Value

For sampleKernelFunction a vector of kernel values at the locations requested. The plot methods are called for their side-effects.
