Lecture 4

It will become increasingly difficult to use software like Excel and SPSS. Perhaps now is a good time to switch to R or Matlab. We do have a spreadsheet example of Standardised Dispersion Anaysis.

Using R: Install functions in nlRtsa_SOURCE.R

First, download (from blackboard) and source('nlRtsa_SOURCE.R'), or source it directly from Github if you have package devtools installed.

library(devtools)
source_url("https://raw.githubusercontent.com/FredHasselman/DCS/master/functionLib/nlRtsa_SOURCE.R")

We need packages signal and pracma Among nlRtsa functions is in.IT(), which will load a list of packages and install them, but only if they are not present on your system.

in.IT(c("signal","pracma"))

You can of course also use install.packages() or the GUI.
