Binary Operators with Implicit Expansion

Description

Modified versions of binary operators that support implicit expansion. Arguments are passed to mmapply() with the corresponding element-wise binary operator. For instance, x %m+% y is equivalent to mmapply('+', x, y).

Usage

x %m+% y

x %m-% y

x %m*% y

x %m/% y

x %m^% y

x %m==% y

x %m!=% y

x %m>% y

x %m<% y

x %m>=% y

x %m<=% y

x %m|% y

x %m&% y

Arguments

x, y	Arrays or objects that can be coerced to arrays using as.array().

Value

The result of mmapply('XXX', x, y), with XXX replaced by the corresponding element-wise binary operator.

Examples

x <- c(1,2,3)
y <- t(c(4,5))
x %m+% y

m <- matrix(3*(1:12)^2, 3, 4)
cm <- t(colMeans(m))
m %m-% cm

(1:3) %m>=% t(3:1)
