gRbase-utilities: Utility functions for gRbase

Description

Utility functions for gRbase package. Includes 'faster versions' of certain standard R functions.

Usage

uniquePrim(x)
setdiffPrim(x,y)
intersectPrim(x,y)
subsetof(x, y)
subsetofList(x, l)
unlistPrim(l, recursive = TRUE, use.names = TRUE)
removeRedundant(l, maximal=TRUE, index=FALSE)

Arguments

x, y

Vectors

l

A list (of vectors)

recursive

logical. Should unlisting be applied to list components of x?

use.names

logical. Should names be preserved?

maximal

If TRUE the maximal terms are returned, if FALSE the minimal terms are returned

index

If TRUE the the index of the maximal/minimal elements of l are returned rather than the subset of maximal or minimal subset of l

Value

• A vector or a logical.

Examples

uniquePrim(c(1,2,3,2,1,2))
setdiffPrim(c(1,3,2), c(2,3,4,5))
unlistPrim(list(c(1,2),c(2,3)))
subsetof(c(1,2),c(1,2,3))
subsetof(c(1,2,3), c(1,2))

l <- list(c(1,2),c(1,2,3),c(2,4),c(5,6), 5)

subsetofList(c(1,2), l)
subsetofList(c(1,2,3,4), l)

removeRedundant(l)
removeRedundant(l, maximal=FALSE)
