Very helpful sir, thank you.
What if character and numeric mix together in Likert scale like, Age interval such as
Age 16-20
21-24
25-28
And Character like Agree, Strongly agree, disagree, neutral etc
How can you solve this problems in R when character and numeric mix together.
Also, how can you clear with the data that is showing NA in Likert table.
