which: Which values in an object are considered TRUE?

In Bioconductor/BiocGenerics: S4 generic functions used in Bioconductor

Which values in an object are considered TRUE?

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

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.

See Also

• base::which for the default which method.

• showMethods for displaying a summary of the methods defined for a given generic function.

• selectMethod for getting the definition of a specific method.

• which,DelayedArray-method in the DelayedArray package for an example of a specific which method (defined for DelayedArray objects).

• BiocGenerics for a summary of all the generics defined in the BiocGenerics package.

Examples

which
showMethods("which")
selectMethod("which", "ANY")  # the default method

library(DelayedArray)
showMethods("which")
## The which() method for DelayedArray objects:
selectMethod("which", "DelayedArray")
