General strategies for hard-to-parse files

Also from R4DS:

Sometimes it's easier to diagnose problems if you just read in all the columns as character vectors:

#| eval: false

df <- read_csv(
  "challenge.csv",
  col_types = cols(.default = col_character())
)

If you're having major parsing problems, sometimes it's easier to just read into a character vector of lines with read_lines():

#| eval: false

df <- read_lines("challenge.csv")

Then you can use dplyr and the tools you'll learn in @sec-strings to figure out what's going wrong.
