Replace Correlation Coefficients by Symbols

Description

Take a correlation matrix and replace the correlation coefficients by symbols according to the level of the correlation.

Usage

cor_as_symbols(
  x,
  cutpoints = c(0, 0.25, 0.5, 0.75, 1),
  symbols = c(" ", ".", "+", "*")
)

Arguments

x

a correlation matrix. Particularly, an object of class cor_mat.

cutpoints

numeric vector used for intervals. Default values are c(0, 0.25, 0.5, 0.75, 1).

symbols

character vector, one shorter than cutpoints, used as correlation coefficient symbols. Default values are c(" ", ".", "+", "*").
