I have a df imported from Stata using the haven package which is automatically changing the types of columns to "haven_labelled" as shown below. There are about 980 columns in total, and I want to convert them to factors while preserving the labels e.g. yes/no.
I tried the as.factor(df) command, but it is not working.
> class(df$smoke)  "haven_labelled"  "vctrs_vctr"  "double"
Please suggest to me if you know of any method to do this.
Thank you in advance!
