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
You get the following output
> foobar()
Running foo
[1] 10
Running bar

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.
