Error when running roxygenise #28
Description
Running roxygenise with a unmodified code lead to the following.
>library(roxygen3)
> roxygenise('.')

@method is deprecated. S3 methods are now detected automatically.
Error in get(as.character(FUN), mode = "function", envir = envir) :

This appears to be an namespace issue with memoise. It can be duplicated using the following code placed in a namespac where foobar, foo, and bar are exported and bob is not exported.
bob <- function(input) {
input + 5
}
foo <- function(process, input) {
a <- match.fun(process)
a(input)
}
bar <- memoise(foo)
foobar <- function() {
cat('Running foo\n')
print(foo('bob', 5))
cat('Running bar\n')
print(bar('bob', 5))
return("done")
}Then running the following code
foobar()You get the following output
> foobar()
Running foo
[1] 10
Running bar
Error in get(as.character(FUN), mode = "function", envir = envir) :
object 'bob' of mode 'function' was not found
Calls: foobar -> print -> bar -> f -> match.fun -> get

6: get(as.character(FUN), mode = "function", envir = envir)
5: match.fun(process) at TempTest.R#6
4: f(...) at memoise.r#28
3: bar("bob", 5)
2: print(bar("bob", 5)) at TempTest.R#18
1: foobar()
so foo() runs correctly however the memoise version of foo() bar() does not. As near as I can tell its because match.fun() is looking for 'bob' in the memoise namespace.
