In Bioconductor/BiocGenerics: S4 generic functions used in Bioconductor

Subsetting vector-like, matrix-like and data-frame-like objects

Description

Return subsets of vector-like, matrix-like or data-frame-like objects which meet conditions.

NOTE: This man page is for the subset S4 generic function defined in the BiocGenerics package. See ?base::subset for the subset S3 generic defined in the base package.

Usage

subset(x, ...)

Arguments

x	A vector-like, matrix-like or data-frame-like object to be subsetted.
...	Additional arguments (e.g. subset, select, drop), for use in specific methods. See ?base::subset for more information.

Value

An object similar to x containing just the selected elements (for a vector-like object), or the selected rows and columns (for a matrix-like or data-frame-like object).
