 summary.mrs R Documentation

## Summary of a mrs object

### Description

This function summarizes the output of the `mrs` function. It provides the marginal prior and posterior null and the top regions of the representative tree.

### Usage

```## S3 method for class 'mrs'
summary(object, rho = 0.5, abs_eff = 0, sort_by = "eff",
...)
```

### Arguments

 `object` A `mrs` object `rho` Threshold for the posterior alternative probability. All regions with posterior alternative probability larger than `rho` are reported. Default is `rho = 0.5`. `abs_eff` Threshold for the effect size. All regions with effect size larger than `abs_eff` in absolute value are reported. Default is `abs_eff = 0`. `sort_by` Define in which order the regions are reported. The options are `sort_by = c("eff", "prob")` and the default is `sort_by = "eff"`. `...` Additional summary parameters.

### Value

A `list` with information about the top regions.

object = mrs(X=X, G=G)
fit = summary(object, rho = 0.5, abs_eff = 0.1)
