diagonal: Diagonal Part of a Matrix

In R-KenK/SimuNet: Network Simulation Framework, with a Zest of Empiricism

Description

Similarly to upper.tri and lower.tri, returns a matrix of logicals to identify the diagonal of a square matrix

Usage

diagonal(M, output = c("matrix.logical", "vector.values"))

Arguments

M	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
output	choose to either return a matrix of logical values (TRUEs on the diagonal, i.e. comparable behavior than diag for instance) or a vector of the subsetted values of the matrix

Value

square logical matrix with diagonal of TRUEs

Examples

M<- matrix(sample(1:10,16,replace = TRUE),4,4)
diagonal(M)
