# plot_kernel

From FKSUM v0.1.0
by David Hofmeyr

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

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

```
# NOT RUN {
### Plot order 4 smooth kernel
plot_kernel(1/factorial(0:4))
### Use a different line style
plot_kernel(1/factorial(0:4), lty = 2)
# }
```
