ReadPosErrorPlot {ReQON} | R Documentation

## Plot distribution of errors by read position.

### Description

Plots the number of sequencing errors by read position.

### Usage

    ReadPosErrorPlot(ReadPosErrors, startpos = 1, error_col = "blue", thresh = 1.5,
       thresh_col = "cyan", xlabel = "Read Position", ylabel = "# Errors",
       main_title = "Distribution of Errors by Read Position")

### Arguments

`ReadPosErrors` | vector of sequencing error counts by read position.
`startpos` | Starting read position, typically 0 or 1. Default = 1.
`error_col` | color of line plotting the errors counts. Default = "blue".
`thresh` | Threshold for identifying read positions with large numbers of errors, plotted as a horizontal dashed line. Threshold is set as “thresh * (average number of errors per read position)”. Default = 1.5.
`thresh_col` | color of threshold line. Default = "cyan".
`xlabel` | x-axis label. Default = "Read Position".
`ylabel` | y-axis label. Default = "# Errors".
`main_title` | title. Default = "Distribution of Errors by Read Position".

### Details

ReadPosErrorPlot plots the distribution of sequencing errors by read position. If the input vector is $ReadPosErrors from ReQON output, this function will create the top left diagnostic plot that is output from ReQON.

For more details and interpretation, see the vignette by: browseVignettes("ReQON").

### Examples

    ## Create data of error counts
    x <- c( 1:30 )
    err <- x^2 + ( 30 - x )^1.6 + rnorm(30, 0, 100)

    ## plot errors by read position
    ReadPosErrorPlot( err )
