3 days ago Yes, this one is a relatively new annoyance. I started just using a csv with the original data in class until I swap it out.

At the top of chapter 13.2 you mention we will be using the crab data set, but don't show the code to load it. Trying data(crab) returns Error: object 'crab' not found. Maybe a typo? data(crabs) works, but returns: head(crabs)

That does not match your results, so I did a little more digging. It would appear there are now 2 crabs data sets, and at least with my configuration, this guyhttps://www.rdocumentation.org/packages/MASS/versions/7.3-61/topics/crabs gets priority.
Good news, I found a work around for now, the "evidence" package looks like it has similar data:
install.packages("evidence") library(evidence) data(HSCrab) head(HSCrab)
Col spineW Width Satell Weight 1 3 3 28.3 8 3050 2 4 3 22.5 0 1550 3 2 1 26.0 9 2300 4 4 3 24.8 0 2100 5 4 3 26.0 4 2600 6 3 3 23.8 0 2100
Given that 3050 = 1000*3.05, I'm guessing this data set is in grams and yours was in kg. This also brings up the annoyance of weight vs mass, but beggars and choosers and all that.
The closest I can currently get is with:
library(evidence) data(HSCrab) HSCrab$mass <- HSCrab$Weight/1000 crabs <- HSCrab[c('Col','spineW','Width', 'mass', 'Satell')] crabs %>% dplyr::rename( color = Col, spine =spineW, width = Width, satellites = Satell, mass = mass ) -> crabs head(crabs)
color spine width mass satellites 1 3 3 28.3 3.05 8 2 4 3 22.5 1.55 0 3 2 1 26.0 2.30 9 4 4 3 24.8 2.10 0 5 4 3 26.0 2.60 4 6 3 3 23.8 2.10 0
str(crabs)
'data.frame': 173 obs. of 5 variables: $ color : int 3 4 2 4 4 3 2 4 3 4 ... $ spine : int 3 3 1 3 3 3 1 2 1 3 ... $ width : num 28.3 22.5 26 24.8 26 23.8 26.5 24.7 23.7 25.6 ... $ mass : num 3.05 1.55 2.3 2.1 2.6 2.1 2.35 1.9 1.95 2.15 ... $ satellites: int 8 0 9 0 4 0 0 0 0 0 ...
From what I can tell, the order of observations is not the same, but hopefully the data is?
