7 The NAMESPACE file
A NAMESPACE file defines the functions, classes, and methods that are imported into the namespace, and exported for users.
In the following section we describe what Bioconductor reviewers will be looking for in this file.
7.1 Function names
Exported functions should use camel case or underscoring and not include .,
which indicates S3 dispatch. Functions starting with . should not be exported
as that indicates an internal function.
7.2 Imported functions
Generally importFrom() is encouraged over importing an entire package.
However, if there are many functions from a single package, import() can be
acceptable. If a particular Bioconductor class is used or extended it is
highly recommended to import() the full package so that full class
functionality is inherited automatically; there are exceptions depending on
implementation and necessity.
