Pull Lower and Upper Triangular Part of a Matrix
Returns the lower or the upper triangular part of a (correlation) matrix.
pull_triangle(x, triangle = c("lower", "upper"), diagonal = FALSE)
pull_upper_triangle(x, diagonal = FALSE)
pull_lower_triangle(x, diagonal = FALSE)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. |

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.
