pull_triangle: Pull Lower and Upper Triangular Part of a Matrix

Description

Returns the lower or the upper triangular part of a (correlation) matrix.

Usage

pull_triangle(x, triangle = c("lower", "upper"), diagonal = FALSE)
pull_upper_triangle(x, diagonal = FALSE)
pull_lower_triangle(x, diagonal = FALSE)

Arguments

x

a (correlation) matrix

triangle

the triangle to pull. Allowed values are one of "upper" and "lower".

diagonal

logical. Default is FALSE. If TRUE, the matrix diagonal is included.

Value

an object of class cor_mat_tri, which is a data frame

Functions

• pull_triangle: returns either the lower or upper triangular part of a matrix.

• pull_upper_triangle: returns an object of class upper_tri, which is a data frame containing the upper triangular part of a matrix.

• pull_lower_triangle: returns an object of class lower_tri, which is a data frame containing the lower triangular part of a matrix.
