## S3 method for class 'FeatureSet':
hist(x, transfo=log2, which=c("pm", "mm", "bg", "both", "all"),
## S3 method for class 'ExpressionSet':
hist(x, transfo=identity, nsample=10000, ...)
FeatureSet or ExpressionSet object
a function to transform the data before plotting. See
number of units to sample and build the plot.
set of probes to be plotted ("pm", "mm", "bg", "both",
arguments to be passed to matplot
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').
