hist: Density estimate

Description

Plot the density estimates for each sample

Usage

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

Arguments

x

FeatureSet or ExpressionSet object

transfo

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

nsample

number of units to sample and build the plot.

which

set of probes to be plotted ("pm", "mm", "bg", "both", "all").

...

arguments to be passed to matplot

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').
