plotDispEsts {DESeq2} | R Documentation

## Plot dispersion estimates

### Description

A simple helper function that plots the per-gene dispersion estimates together with the fitted mean-dispersion relationship.

### Usage

    ## S4 method for signature 'DESeqDataSet'
    plotDispEsts(object, ymin, CV = FALSE,
      genecol = "black", fitcol = "red", finalcol = "dodgerblue",
      legend = TRUE, xlab, ylab, log = "xy", cex = 0.45, ...)

### Arguments

`object` | a DESeqDataSet, with dispersions estimated
`ymin` | the lower bound for points on the plot, points beyond this are drawn as triangles at ymin
`CV` | logical, whether to plot the asymptotic or biological coefficient of variation (the square root of dispersion) on the y-axis. As the mean grows to infinity, the square root of dispersion gives the coefficient of variation for the counts. Default is `FALSE`, plotting dispersion.
`genecol` | the color for gene-wise dispersion estimates
`fitcol` | the color of the fitted estimates
`finalcol` | the color of the final estimates used for testing
`legend` | logical, whether to draw a legend
`xlab` | xlab
`ylab` | ylab
`log` | log
`cex` | cex
`...` | further arguments to `plot`
