This problem with "!" in the beginning of line:
Hint: !is.na(c(3, 5, NA, 10)) will negate the previous command, thus telling us what is NOT NA.
I think the most useful solution:
- Class: cmd_question
Output: 'Now, put an exclamation point (!) before is.na() to change all of the TRUEs to FALSEs and all of the FALSEs to TRUEs, thus telling us what is NOT NA: !is.na(c(3, 5, NA, 10)).'
CorrectAnswer: "!is.na(c(3, 5, NA, 10))"
AnswerTests: omnitest('!is.na(c(3, 5, NA, 10))')
Hint: Expression !is.na(c(3, 5, NA, 10)) will negate the previous command, thus telling us what is NOT NA.```
