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').
