Calculate Cosine Measures

cosine(x, y)

## Arguments

x a numeric vector or matrix with column representing vector to calculate similarity. must be same format as x.

## Value

a numeric value or matrix.

## Examples

x <- c(1, 1, 1, 0, 0, 0, 0, 0, 0, 0, 0, 0)
y <- c(0, 0, 1, 1, 1, 1, 1, 0, 1, 0, 0, 0)
z1 <- cosine(x, y)
z1
z2 <- cosine(matrix(x), matrix(y))
z2
