oligo (version 1.36.1)

boxplot: Boxplot

Description

Boxplot for observed (log-)intensities in a FeatureSet-like object (ExpressionFeatureSet, ExonFeatureSet, SnpFeatureSet, TilingFeatureSet) and ExpressionSet.

Usage

## S3 method for class 'FeatureSet':
boxplot(x, which=c("pm", "mm", "bg", "both", "all"), transfo=log2, nsample=10000, ...)
## S3 method for class 'ExpressionSet':
boxplot(x, which, transfo=identity, nsample=10000, \dots)

Arguments

x

a FeatureSet-like object or ExpressionSet object.

which

character defining what probe types are to be used in the plot.

transfo

a function to transform the data before plotting. See 'Details'.

nsample

number of units to sample and build the plot.

...

arguments to be passed to the default boxplot method.

Details

The 'transfo' argument will set the transformation to be used. For raw data, 'transfo=log2' is a common practice. For summarized data (which are often in log2-scale), no transformation is needed (therefore 'transfo=identity').
