Description

Fast but loose implementations of AND and OR logical operators.

Usage

and0(x, y)
or0(x,y)

Arguments

x,y

A logical or numeric vector.

Value

• A logical vector of length max(length(x), length(y)) containing

Details

Returns pairwise application of logical operators AND and OR. Vectors are recycled as usual.

Examples

and0(c(0,1,0),c(1,1,0))

set.seed(1234)
x = rbinom(5000, 1, 0.5)
y = rbinom(5000, 1, 0.5)

system.time(for (i in 1:5000) and0(x,y))
system.time(for (i in 1:5000) x & y)
