sum_vector: Sum Over Matrix Rows / Columns

In itamarfaran/corrfuncs: Analysis of populations of correlation matrices

Description

Sum over specified matrix rows / columns, possibly weighted. Useful for creating multivariate ARMA processes.

Usage

sum_vector(matr, index, constants, weights = FALSE, by_row = TRUE)

Arguments

matr	matrix to sum over rows / columns
index	index of rows / columns to sum. default is to sum over all rows.
constants	constants to multiply the indices before summation. default is 1 for all constants
weights	should treat constants as weights? if true, weights <- weights/sum(weights). default false
by_row	should sum over rows (default) or by columns?

Value

a vector, built from the (possible weighted) sum of specified vectors
