@renozao renozao commented Sep 22, 2011

in one of the R files I have something like this, that defines a temporary function in order to define a static variable:

f<- function(){
   .a<- 0
   function(x=1){
     .a<<- .a + x
     .a
   }
}
f2<- f()
rm(f)

When running roxygenise on this I get the error:
Error in eval(expr, envir, enclos) : object 'f' not found

If on removes the call to rm, there is no error.
