In dcbdan/s525: Implementation of common Bayesian models

Description

Sum along a chosen dimension of an arbitrarily dimensioned array.

Usage

  sumAlong <- function(x, along)

Arguments

x	An n dimensional array
along	the dimension of x to sum along

Details

# The method of the source code came from Hadley Wickham: # https://stackoverflow.com/questions/14500707/select-along-one-of-n-dimensions-in-array

This function returns an n - 1 dimensional array that is the result of summing along the along dimension.

Examples

  nx = 3
  ny = 3
  nz = 3
  x = array(1:(nx*ny*nz), dim = c(nx, ny, nz))

  print(x)
  sumAlong(x, 3)
