I have a variable from a data frame, which contains the following statement: "Immigrants should be required to adjust to the customs of Germany". The categories of the variable are strongly agree, agree, neither, disagree, strongly disagree. Here is a frequency table of the variable:
> count(dat, 'c2a')
c2a freq
1 agree 201
2 disagree 214
3 neither 156
4 no answer 15
5 strongly agree 65
6 strongly disagree 138
I would like to recode the variable from text to numbers. I do it the following way:
library(dplyr)
dat$c2a <- recode(dat$c2a, 'strongly disagree' = 1, 'disagree' = 2,
'neither' = 3, 'agree' = 4, 'strongly agree' = 5)
But then I get the following warning message from R: Warning message: Unreplaced values treated as NA as .x is not compatible. Please specify replacements exhaustively or supply .default
How can I specify that all values of c2a which are different from 1 or 2 or 3 or 4 or 5 are NAs?
