which: Which values in an object are considered TRUE?

Description Usage Arguments Value See Also Examples

Description

Give the indices of the values in a vector-, array-, or list-like object that are considered TRUE, allowing for array indices in the case of an array-like object.

NOTE: This man page is for the which S4 generic function defined in the BiocGenerics package. See ?base::which for the default method (defined in the base package). Bioconductor packages can define specific methods for objects (typically vector-, array-, or list-like) not supported by the default methods.

Usage

1
which(x, arr.ind=FALSE, useNames=TRUE)

Arguments

x

An object, typically with a vector-, array-, or list-like semantic.

arr.ind, useNames

See ?base::which for a description of these arguments.

Value

See ?base::which for the value returned by the default method.

Specific methods defined in Bioconductor packages should behave as consistently as possible with the default method.
