For tidyverse 1.3.1, the output of read_csv to the console when reading cats.csv appears to be different to the output in the course materials.

> cats <- read_csv("https://chryswoods.com/intermediate_r/data/cats.csv")
Rows: 144 Columns: 3                                              
 0s── Column specification ────────────────────────────────────────────
Delimiter: ","
chr (1): Sex
dbl (2): BodyWeight, HeartWeight

ℹ Use `spec()` to retrieve the full column specification for this data.
ℹ Specify the column types or set `show_col_types = FALSE` to quiet this message.

The console output in the course materials can be retrieved by running spec(cats):

cols(
  Sex = col_character(),
  BodyWeight = col_double(),
  HeartWeight = col_double()
)
