Description

The variable names of a function are transformed from plain variable names to data.frame names of the form x$<globalName>.

Usage

plainNames2data.frameNames(modelFunction, plainNames)

Value

The transformed function which is of the form:

   function(x){
     ...
     <expression with x$variable1>
     ...
   }

modelFunction

a function whose body contains variables with plain names. The function must not contain any arguments.

plainNames

a character vector containing the names of the variables that shall be transformed.

     ...
   }

 }
 profit2<-plainNames2data.frameNames(modelFunction=profit1, 
                                               plainNames=c("revenue", "costs"))
 print(profit2)
