vstExprs {monocle} | R Documentation

## Return a variance-stabilized matrix of expression values

### Description

This function was taken from the DESeq package (Anders and Huber) and modified to suit Monocle's needs. It accpets a either a CellDataSet or the expression values of one and returns a variance-stabilized matrix based off of them.

### Usage

    vstExprs(cds, dispModelName = "blind", expr_matrix = NULL,
      round_vals = TRUE)

### Arguments

`cds` | A CellDataSet to use for variance stabilization.
`dispModelName` | The name of the dispersion function to use for VST.
`expr_matrix` | An matrix of values to transform. Must be normalized (e.g. by size factors) already. This function doesn't do this for you.
`round_vals` | Whether to round expression values to the nearest integer before applying the transformation.
