# resolveLoop: Resolve loops 'resolveLoop' resolve loops by adding suffix to... In TreeSummarizedExperiment: TreeSummarizedExperiment: a S4 Class for Data with Tree Structures

## Description

Resolve loops `resolveLoop` resolve loops by adding suffix to the child node. The suffix is "_i" where 'i' is a number. Please see examples.

## Usage

 `1` ```resolveLoop(tax_tab) ```

## Arguments

 `tax_tab` a data frame where columns store hierarchical levels. The columns from the left to the right correspond nodes from the root to the leaf.

a data frame
