plot_pc_matern(

range_prob = 0.05,
sigma_prob = 0.05,
range_lims = c(range_gt * 0.1, range_gt * 10),

)
```

## Arguments

- range_gt
A value one expects the spatial or spatiotemporal range is
**g**reater **t**han with `1 - range_prob`

probability.

- sigma_lt
A value one expects the spatial or spatiotemporal marginal
standard deviation (`sigma_O`

or `sigma_E`

internally) is **l**ess **t**han
with `1 - sigma_prob`

probability.

- range_prob
Probability. See description for `range_gt`

.

- sigma_prob
Probability. See description for `sigma_lt`

.

- range_lims
Plot range variable limits.

- sigma_lims
Plot sigma variable limits.

## Value

A plot from `image()`

.
Invisibly returns the underlying matrix data. The rows are the sigmas. The
columns are the ranges. Column and row names are provided.

## Examples

```
plot_pc_matern(range_gt = 5, sigma_lt = 1)
plot_pc_matern(range_gt = 5, sigma_lt = 10)
plot_pc_matern(range_gt = 5, sigma_lt = 1, sigma_prob = 0.2)
plot_pc_matern(range_gt = 5, sigma_lt = 1, range_prob = 0.2)
