How to remove NAs from categorical data?

Question

My data goes like this:

survey <- data.frame("Death" = c(1, 1, 1, NA, 0,1,NA,0,1,0),
                     "recover" = c(0, 0, 0, NA, 1,NA,0,1,0,NA))

My desired output is to replace NAs with the same data from the similar column.

I have tried mutations, but the answer is not coming correctly.

Answer 1

In base R we could use complete.cases to get cases without NA

survey_complete <- complete.cases(survey)
survey[survey_complete,]

Output:

> survey[survey_complete,]
  Death recover
1     1       0
2     1       0
3     1       0
5     0       1
8     0       1
9     1       0
