Dear Proloy Barua

To create a new variable or to transform an old variable into a new one, usually, is a simple task in R. The common function to use is newvariable

Dear Qamar Ul Islam Thank you for suggestions. My problem is a bit different. I actually want to fill up variable value in the NewVar based on four other variables. I attached an example what I want. The value for each observation will be variable name with minimum score (seems funny). Thanks

Dear Proloy Barua

I would suggest using the case_when() function from the "dplyr" package.

The code should be something like:

df_new %

mutate(NewVar = case_when(

Dear Francesco Sanmarchi Thank you so much . It worked

Thanks
