summary.gsaResult: Summarize gene set analysis results

Description

Prints a summary of a gene set analysis result object.

Usage

# S3 method for gsaResult
summary(object,
		mode = c("summary", "table"),
		orderBy = c("adjustedPValues", "rawPValues", "geneSetName"),
		significantOnly = FALSE,
		signLevel = object$signLevel,
		...)

Value

Returns a data.frame with a summary of the produced results such as data set name, p-values, size of the given gene set.

Arguments

object

A result object as returned by geneSetAnalysis.

mode

Specifies the type of information that is displayed: By default (mode="summary"), a brief summary of the number of significant and insignificant gene sets is printed. For mode="table", createSummaryTable is called, and a detailed table of adjusted and unadjusted p-values and the number of genes for each gene set is printed.

orderBy

If mode="table", this specifies which field should be used for the row ordering. By default, rows are ordered according to the adjusted p-values.

significantOnly

If mode="table", this specifies whether all gene sets (significantOnly=FALSE) or only the statistically significant gene sets (significantOnly=TRUE) should be included in the table.

signLevel

If mode="table" and significantOnly=TRUE, this specifies the significance level for the results that should be included in the table. By default, the original significance level of the analysis is used.
