A function for plotting the diagnostic information when classifying a specific pair (defined by the row number or pair name) of individuals. Output includes the PDFs for each degree of relatedness (given the number of overlapping SNPs) in panel A, and the normalised posterior probabilities for each possible degree of relatedness.

## Usage

```
plotSLICE(
in_tibble,
row,
title = NULL,
class_prior = rep(1/4, 4),
showPlot = TRUE,
which_plot = 0,
labels = NULL
)
```

## Arguments

- in_tibble
a tibble that is the output of the callRelatedness() function.

- row
either the row number or pair name for which the posterior distribution is to be plotted.

- title
an optional title for the plot. If NULL, the pair from the user-defined row is used.

- class_prior
the prior probabilities for same/twin, 1st-degree, 2nd-degree, unrelated, respectively.

- showPlot
If TRUE, display plot. If FALSE, just pass plot as a variable.

- which_plot
if 1, returns just the plot of the posterior distributions, if 2 returns just the normalised posterior values. Anything else returns both plots.

- labels
a length two character vector of labels for plots. Default is no labels.
