everything you always wanted to know about

~ latest version ~

☞ The R package for the text is astsa. The Springer version was written under v1.8 but everything should work with minor differences with the latest version, which will always be on GitHub. If you want to update the package to the most recent version, you just need the following two lines:

install.packages("devtools")     # only need to do this once
devtools::install_github("nickpoison/astsa")

If this gives an error, just reissue the installation command. Details about the updates and the current version of the package are on the NEWS page.

As with all packages, you have to load astsa before you use it by issuing the command
library(astsa)
This can be automated by creating a .First function. For example, start R, type
.First <- function(){library(astsa)}
and save the workspace when you quit... now astsa will be loaded at every start until you remove or change .First. This doesn't work with RStudio, you have to create a text file called .Rprofile in the working directory and then add the line library(astsa) and anything else you want to run at startup.

Using Rstudio on a small screen will sometimes lead to an error with anything that produces a graphic such as sarima. That is a problem with Rstudio: Problem with Plots or Graphics Device

version 1.8 is on CRAN

☞ I won't always push the latest version of the package to CRAN because sometimes it's a pain working with those people. If you want to download and install astsa from CRAN, start an R session and issue the command
install.packages("astsa")
You will be asked to download the file from the nearest repository. The text was written under version 1.8. If you use the latest version, there will be only minor differences from the text examples. For the most part, versions after 1.8 added data and scripts for the new Chapman & Hall test.
