Multiplies two matricies. A wrapper around 'matmalt()' (i.e. ' 'data.frame's

Usage

mm(x, y, return_matrix)

"%mm%"(x, y, return_matrix)

Arguments

x

A numeric matrix or vector

y

A numeric matrix or vector

return_matrix

Defaults to returning a data.frame (FALSE). Set to TRUE to return a matrix

Value

The matrix product as a data.frame or matrix

The matrix product as a data.frame or matrix

Examples


x <- data.frame(a=c(1,2,3), b=c(5,6,7))
y <- c(2,2)
mm(x, y)


x <- data.frame(a=c(1,2,3), b=c(5,6,7))
y <- c(2,2)
x %mm% y
