Which values in an object are considered TRUE?
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.
which(x, arr.ind=FALSE, useNames=TRUE)
x |
An object, typically with a vector-, array-, or list-like semantic. |
arr.ind, useNames |

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.
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.
