So I'm doing my research for the final assignment at Coursera and the thing is that the nested ifelse statement doesn't work as expected.

Below is the code I've implemented.

topic <- topic %>%
  filter(!is.na(fear), !is.na(owngun), !is.na(partyid))

topic <- topic %>%
  mutate(fear = as.numeric(fear)) %>%
  mutate(owngun = as.numeric(owngun))

topic %>%
  group_by(fear, owngun) %>%
  summarise(count = n())

topic <- topic %>%
  mutate(fear_gun = ifelse(fear == 1 && owngun == 1, 1, ifelse(fear == 1 && owngun == 2, 2, ifelse(fear == 2 && owngun == 1, 3, ifelse(fear == 2 && owngun == 2, 3, -1)))))

topic %>%
  group_by(fear_gun) %>%
  summarise(count = n())

And here is the result.

So it seems like the result is not correctly sorted. What's the problem here?

Why do you need `&&` Try with single `&` – akrun Jun 08 '17 at 09:58

As a gun enthusiast, I would appreciate a reproducible example. :) – Roman Luštrik Jun 08 '17 at 09:58
@RomanLuštrik Oh this is just a part of the research topic I'm doing. So the result of the inference would be broader than the thing showed on the code. – user3551261 Jun 08 '17 at 10:01
@akrun So "AND" in R is &, not &&? – user3551261 Jun 08 '17 at 10:02

@zx8754 Thanks. This really helps. – user3551261 Jun 08 '17 at 10:04
Can we close as duplicate? – zx8754 Jun 08 '17 at 10:05
@zx8754 I'll just leave my own answer cause I'm in danger of being banned. – user3551261 Jun 08 '17 at 10:07
@zx8754 Yes, I can close it, if everybody agrees :-) – akrun Jun 08 '17 at 11:27
@akrun I am not sure if OP is happy to close, I didn't understand his above comment regarding "banned". – zx8754 Jun 08 '17 at 11:32
@zx8754 Probably bcz he thinks if all his questions are dupe tagged, his id will be banned for asking more questions. I don't know the rules either – akrun Jun 08 '17 at 11:33
I don't see any dupe closed questions in OP's history. – Axeman Jun 08 '17 at 11:48
