condense: Condenses columns of matrix

In DecomposeR: Empirical Mode Decomposition for Cyclostratigraphy

Condenses columns of matrix

Description

Condenses columns of a matrix by averaging or summing them. The condensing can be done partially: a multiple of the repetitions can be averaged or summed to keep some repetitions.

Usage

condense(m, n, fun = "mean")

Arguments

m	matrix of repeated signal, each column being a repetition
n	the number of repetitions that will be averaged/summed
fun	the function to apply to each repetition: "mean" or "sum".

Value

a matrix with n times less columns

Examples

m <- matrix(rep(seq(100, 800, 100), each = 10) + rep(1:10, 8), ncol = 8)

m

condense(m, 4)
