Calculate Cosine Measures

Calculate Cosine Measures

cosine(x, y)

Arguments

x

a numeric vector or matrix with column representing vector to calculate similarity.

y

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
#> [1] 0.2357023
z2 <- cosine(matrix(x), matrix(y))
z2
#>           [,1]
#> [1,] 0.2357023
