In cytomining/cytominer: Methods for Image-Based Cell Profiling

Compute covariance matrix and vectorize.

Description

covariance computes the covariance matrix and vectorize it.

Usage

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")
