I need to set a function that help me in restore the Yes/No variable in 0/1 one.

A function should be

x<-function(DataFrame,VariableName,Yes,No){
   .....
  }

I set up this code but run only out the function because R do not read the variable setted in () after the dollar sign.

dummy<-function(DB,varr){
        BD$varr <- as.character(DB$varr)
        DB[BD$varr=="Yes"]<-"1"
        DB[BD$varr=="No"]<-"0"
}

  • Use `[` instead of `$`. – Roland Jan 03 '17 at 10:29

    `x<-function(DataFrame,VariableName,Yes) { as.integer(DataFrame[VariableName]==Yes) }` should do for your overall question. – Tensibai Jan 03 '17 at 10:36
  • For its use: `DB$Varr <- x(DB,"Varr","Yes")`. As an advice:don't try to update an external object in a function, even if you exactly know the caveats behind this idea, it's usually brittle and a nightmare to maintain. – Tensibai Jan 03 '17 at 10:44

We can use as.integer to coerce the logical vector to binary

as.integer(BD$varr=="Yes")
