R code for graphics of Time Series Analysis and Its Applications, Ed 4

tsa4

• Because R code takes up so much space in the text, most of the R code for the graphics in Time Series Analysis and Its Applications, Edition 4 was shortened to the minimum number of lines needed to get a decent plot.

• The actual code used in the text for the graphics is listed in these xxx.R files.

• Some of the code was written before astsa took full form and was the incentive to write our own scripts. For example, in Chapter 1, you might see 10 or more lines just to get the ACF and PACF on the same scale... this stuff was written before acf2 and I never updated it because it did the job.

• The code for data analysis is shown in the text exactly as it was used. All that stuff is on the website for the text.

• grid.r as listed here was used instead of writing out the details each time... the change was to col = gray(.9), lty = 1 in the defaults from the original col = "lightgray", lty = "dotted" ... not a big deal but a pain if it's called a lot.

• Chapter 7 code is long, so there are a number of files in that directory.

• The use of ggplot2 in the new edition of the text was considered for about 2 seconds, but it's not what the text is about and it would have added too much space to address it. Instead, a web page is devoted to ggplot, ggfortify and base graphics. See the graphics fix page at tsa4.
