plot_kernel {FKSUM}

Plot the shape of a kernel function implemented in FKSUM based on its vector of beta coefficients

Description

Plots the kernel function for a given set of beta coefficients. NB: coefficients will be normalised so that the kernel describes a probability density.

Usage

plot_kernel(beta, type = 'l', ...)

Arguments

beta

positive numeric vector of kernel coefficients.

type

(optional) plot type, as in base plot() function. The default is a line plot.

...

(optional) any additional arguments accepted by base plot() function.

Examples

### Plot order 4 smooth kernel

plot_kernel(1/factorial(0:4))

### Use a different line style

plot_kernel(1/factorial(0:4), lty = 2)
