Source: R/covariance.R

covariance computes the covariance matrix and vectorize it.

covariance(population, variables)

Arguments

population

tbl with grouping (metadata) and observation variables.
variables

character vector specifying observation variables.

Value

data frame of 1 row comprising vectorized covariance matrix.

Examples


population <- tibble::tibble(
  x = rnorm(30),
  y = rnorm(30),
  z = rnorm(30)
)

variables <- c("x", "y")

covariance(population, variables)

#>        x__x      y__x     y__y
#> 1 0.9379415 0.3075673 0.907543
