Known Errors in the 1st edition

To be fixed for the third printing

  • Page 11: The caption should say “USD” instead of “millions of USD”. (rporta)
  • Page 37: The end of the last sentence should read “corresponds to a value of 30 roadways per unit area”. (mhilton)
  • Page 91: The key for the Google spreadsheet has changed. Try hiv_key <- "1kWH_xdJDM4SMfT_Kzpkk-1yuxWChfurZuWYjfmv51EA" instead. (mwan)
  • Page 156: “We can compare this to a (hypothetical) sample of size \(n = 1,000\)” should be “We can compare this to a (hypothetical) sample of size \(n = 200\)” (zzhang)
  • Page 282: A comma is missing in the SQL query that causes the dest column to be erroneously labelled flight. (kbaker)
  • Page 310-313: There is inconsistent usage of babynamedb and babynamedata. All references should be to babynamedb. (kbaker)
  • Page 378: “The diameter of a graph is the length of the longest geodesic between any [two] pairs of vertices.” The word “two” should be removed. (agary)
  • Page 379: A parenthesis is missing after “(see Figure 16.1”. (bbaumer)

Fixed for the second printing

  • Page 10: The last sentence should start “It also seems clear” instead of “In also seems clear”. (voberholzer)

Votes_wide <- Votes %>%
  tidyr::spread(key = bill, value = vote)

  • Page 375: Exercise 15.4 should read: “Find all of the adjectives in one of Shakespeare’s plays that end in more or less.” (nhorton/bbaumer)
