@mchien20 can you please be sure to extirpate any use of $ in the files? (If this is coming from SDM4 we'll want to fix it there as well):

"Nightmares$Dream <- ifelse(Nightmares$Dream == "N", "Nightmare", "SweetDreams")

should be:

Nightmares <- Nightmares %>% mutate(Dream = recode(... etc.)

If you prefer to use ifelse I wouldn't object (but it's important to change to mutate).

For questions such as: "#### Example 3.5: Looking for Associations in Large Data Sets: Text Messages

Not sure where the data is

in future can you please post an issue and provide a specific page ref?
