lower_tri: Find and return the lower triangle of a matrix

Description

Same as lower.tri() except it returns the values from the matrix (rather than a positional matrix that lets you look up the values).

Usage

lower_tri(x, diag = FALSE)

Value

The values in the lower triangular part of the matrix.

Arguments

x

a matrix or other R object with length(dim(x)) == 2. For back compatibility reasons, when the above is not fulfilled, as.matrix(x) is called first.

diag

logical. Should the diagonal be included?
