Exported function not exported correctly

Question

I am developing an R package (let's call it pkg), and I have defined a few generics. The NAMESPACE file contains both

S3method(foo, bar)
export(foo)

However, upon calling pkg::foo.bar, I get the dreaded

Error: 'foo.bar' is not an exported object from 'namespace:pkg'

I am using roxygen2, if that changes anything.

Note: If I explicitly add export(foo.bar), then everything works.

if you use devtools, @export for all generic/methods? it always worked fine for me (more doc here. Is foo a method you created or do you extend one ? – Jumble

Yes, all generics are exported.foo is a method that I created, and is being called from another package I am writing (e.g. secondPkg imports pkg and is trying to call pkg::foo.bar). – Pacheco

I had same problem...many expletives later I discovered that NAMESPACE (and thus exports) is only updated when you run devtools::document() - not devtools::build() or devtools::install() – Torrent

@virgesmith: This solved my problem too. Please consider writing an answer. – Kempis

NAMESPACE (and thus exports) is only updated when you run devtools::document() - not devtools::build() or devtools::install().
