plotCNEDistribution {CNEr} | R Documentation

## Plot sequential CNE number against CNE genomic location

### Description

Plot the CNE genomic location distribution. It gives an overview of the tendency of CNEs to form clusters.

### Usage

      plotCNEDistribution(x, chrs = NULL, chrScale = c("Mb", "Kb"))

### Arguments

`x` | `GRanges` object: the CNE locations.
`chrs` | `character`(n): the chromosomes to show. By default, the largest 6 chromosomes/scaffolds are selected.
`chrScale` | `character`(1): the chromosome/scaffold scale of ‘Mb’ or ‘Kb’ in the plot.

### Details

In the plot, x axis is the genomic location along each chromosome/scaffold. The y axis is the sequential CNE number. A typical CNE cluster can be spotted by the dramatic increase in y axis and small increase in x axis.

### Value

A `ggplot` object.
