sim_cor_mat: Simulate a correlation matrix from a given nb of variables

In FrankLef/eflStats: Tools used in statistical analysis by FL

Description

Simulate a correlation matrix from a given nb of variables.

Usage

sim_cor_mat(nvars = 2, is_cor = TRUE)

Arguments

nvars	Positive number of variables, must be >= 2.
is_cor	TRUE (default): Return the correlation matrix. FALSE: return the covariance matrix.

Details

Simulate a correlation matrix from a given nb of variables by creating a covariance matrix and transforming it to a correlation matrix with stats::cov2cor. The method was copied from simstudy::genCorMat() to whom I express my gratitude.

Value

Correlation matrix nvars x nvars

Examples

mat <- sim_cor_mat(4)
stopifnot(identical(dim(mat), c(4L, 4L)))
