Page 95: in Exercise 5.1, in entry b.iii., "num" should read as "nums"
Pages 101-102: The answer for Exercise 5.2 (a) has been updated in the resources file. In the call to data.frame, the correct use should have stringsAsFactors=F.
Page 135: The paragraph at the bottom of the page should read:
...This line of code adds two separate horizontal lines, one at y = -5 and the other at y = 5, using h= c(-5,5).
Page 155: The website address within the code lines should read as:
R> dia.url <- "http://www.amstat.org/publications/jse/v9n2/4Cdata.txt"
Page 206: The website address within the first code line at the bottom of the page should read as:
R> dia.url <- "http://www.amstat.org/publications/jse/v9n2/4Cdata.txt"
Page 213: Exercise 10.6 (a) (i) should read: ...That is, produce the same vector as loop1.result in the text.
Exercise 10.6 (a) (ii) should read: Obtain the same result as loop2.result, the example...
Page 214: In Exercise 10.6 (c) (ii), the code listing line that reads:
matlist1 <- list(matrix(1:4,2,2),matrix(2:5,2,2)
matrix(1:16,4,2))
should read:
matlist1 <- list(matrix(1:4,2,2),matrix(2:5,2,2)
matrix(1:16,8,2))
Page 238: Exercise 11.3 (b) (ii) should read: 12 factorial is 479,001,600.
Page 280: In Equation 13.6, the index of the sum should be i = 1 rather than i - 1.
Page 307: The answer for Exercise 14.1 (i) has been updated in the resources file. It should appear as follows:
magquan <- quantile(quakes$mag,c(1/3,2/3))
magfac <- cut(quakes$mag,breaks=c(min(quakes$mag),magquan[1],
magquan[2],max(quakes$mag)), include.lowest=TRUE)
Page 317: In the final line of Equation 15.4, a power of 2 should appear after the first set of parentheses.
Page 325: Equation 15.8 should read:
Page 352: In Figure 16-7, the legend should read: (mean - 1 sd)
Page 363: The Note at the end of Section 16.2.5 should read:
...However, most p- and q-functions in R include an optional logical argument, lower.tail, which defaults to TRUE. Therefore, an alternative is to set lower.tail=FALSE in any relevant function call...
Page 489: In the final code listing in Section 21.2.3, the line that reads:
R> BETA.HAT <- solve(t(X)
Should instead read:
R> BETA.HAT <- solve(t(X)%*%X)%*%t(X)%*%Y
The correct line appears in the resources file, Davies_Part4_Source_Code.R.
Page 530: In Equation 22.1, the last line should read:
HA : At least one of the βj 6 ≠ 0 (for j = p + 1, . . . , q)
Page 568: The website address within the first line of code in the middle of the page should read:
R> dia.url <- "http://www.amstat.org/publications/jse/v9n2/4Cdata.txt"
Page 590: In Exercise 23.1 (c), the line that reads:
After you open the device and setting the layout, the plot margins...
should read:
After you open the device and set the layout, the plot margins...
Page 606: In Exercise 23.2, the website address within the first line of code at the top of the page should read:
R> dia.url <- "http://www.amstat.org/publications/jse/v9n2/4Cdata.txt"
Page 619: For later versions of ggplot2, the commands do not center the title, but have it flush-left. In order to center the title, add theme(plot.title = element_text(hjust = 0.5) ) to the code.
Page 637: The last line of code at the top of the page that reads:
R> axis(2,at=4:1,labels=c("peryel.colors"...
should read:
R> axis(2,at=4:1,labels=c("puryel.colors"...
Page 671: In Section 25.5.2, install.package("spatstat") should be install.packages("spatstat").
Page 698: In Exercise 26.1 (b), the first line in the legend of the figure should read: Male RH.

2.002741e-05
should read:
2.567628e-05
Page 719: The last line of code in the middle of the page that reads:
3.649565e-05
should read:
4.890472e-05
