[Roxygen-devel] [roxygen2] error sourcing the R files (probably environment issue)

[Renaud Gaujoux]

Hi,

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

No error with R CMD check.
If I use the -- very nice -- function devtools::load_all, it works 
perfectly fine as well.

In this simple case I know I could do f <- f() instead and remove the 
problematic call to rm (and it works fine).
But my actual use case is to define a S4 method like this:

setMethod('A', 'ANY', f())
rm(f)

Here I really need to remove not to have it remaining in my namespace.

Does roxygen2 source the R files differently?
Maybe there is an alternative way to define static variables for my use 
case, that would not break roxygenise?

Thank you

Renaud
