Create a full D (between subject variability) matrix given a vector of variances and covariances. Note, this does not test matching vector lengths.

Create a full D (between subject variability) matrix given a vector of variances and covariances. Note, this does not test matching vector lengths.

Usage

getfulld(variance_vector, covariance_vector = NULL)

Arguments

variance_vector

The vector of the variances.

covariance_vector

A vector of the covariances. Written in column major order for the lower triangular matrix.

Value

The full matrix of variances for the between subject variances

Examples

getfulld(c(1,2,3))
#>      [,1] [,2] [,3]
#> [1,]    1    0    0
#> [2,]    0    2    0
#> [3,]    0    0    3

getfulld(c(1,2,3),c(7,6,5))
#>      [,1] [,2] [,3]
#> [1,]    1    7    6
#> [2,]    7    2    5
#> [3,]    6    5    3
