I have data of a Likert scale questionnaire regarding alcohol consumption and cigarette smoking. I want to look for a correlation between the 2 variables in R but I am a complete R newbie and don’t understand why it doesn’t work. The code I tried:

CrossTable(Do.you.consume.alcohol, Do.you.smoke.cigarettes , chisq = TRUE , expected = TRUE)

That’s the error message I get:

Error in CrossTable(Do.you.consume.alcohol, Do.you.smoke.cigarettes ,  : 
object 'Do.you.consume.alcohol' not found.

Does anybody know why is the object not found?

    First of all it would be nice if you provide your actual code. We can't help you with guessing what's wrong. Second it would be good if you provide a sample dataset. In R you can use dput(your_dataset) to provide it to other users. – pbraeutigm Aug 09 '21 at 07:18
  • thanks for the willingness to help! it might be a stupid question but how do i provide the sample dataset here? my code is: df <- read.csv("/Users/itamarmichaeli/Desktop/alcohol.and.smoking.csv") library(gplots) CrossTable(Do.you.consume.alcohol, Do.you.smoke.cigarettes , chisq = TRUE , expected = TRUE) – jim halpert Aug 09 '21 at 07:53
  • Try `df$Do.you.consume.alcohol` instead of simply `Do.you.consume.alcohol`. The same for the cigarettes. – Martin Gal Aug 09 '21 at 07:57

    In R Studo you can use dput(your_dataset) to provide it to other users. https://stackoverflow.com/questions/49994249/example-of-using-dput – pbraeutigm Aug 09 '21 at 08:08
