matboxplot {quantro} | R Documentation

## Box plots of columns in a matrix

### Description

Box plots of the columns of a matrix, but the columns are ordered and colored by a group-level variable

### Usage

    matboxplot(
      object,
      groupFactor,
      las = 3,
      brewer.n = 8,
      brewer.name = "Dark2",
      ...
    )

### Arguments

`object` | object an object which is inherited from an `eSet` such as an `ExpressionSet` or `MethylSet` object. The `object` can also be a data frame or matrix with observations (e.g. probes or genes) on the rows and samples as the columns.
`groupFactor` | a factor variable representing which group each column in `object` belongs to. It is important that values in `groupFactor` be in the same order as the columns in `object`.
`las` | a numeric in (0, 1, 2, 3) to orient the axis labels. Default is 3 (always vertical).
`brewer.n` | the number of colors in the palette from the RColorBrewer package. Default is 8.
`brewer.name` | the name of the palette from the RColorBrewer package. Default is "Dark2".
`...` | other arguments that can be passed to the codeboxplot function.

### Value

A box plot for each column in `object`

### Examples

    library(minfi)
    data(flowSorted)

    p <- getBeta(flowSorted, offset = 100)
    pd <- pData(flowSorted)
    matboxplot(object = p, groupFactor = pd$CellType)
