Display q-value object

Description

Display summary information for a q-value object.

Usage

## S3 method for class 'qvalue'
summary(object, cuts = c(1e-04, 0.001, 0.01, 0.025, 0.05,
  0.1, 1), digits = getOption("digits"), ...)

Arguments

object	A q-value object.
cuts	Vector of significance values to use for table (optional).
digits	Significant digits to display (optional).
...	Additional arguments; currently unused.

Details

summary shows the original call, estimated proportion of true null hypotheses, and a table comparing the number of significant calls for the p-values, estimated q-values, and estimated local FDR values using a set of cutoffs given by cuts.

Value

Invisibly returns the original object.
