I'd like to be able to access unexported functions in the testing code
for a package with a namespace. I know that one way to do this is to
use the ":::" operator, but I'd prefer to avoid cluttering up my testing
code with lots of repetitions of "myPackageName:::".
One way I found to do this was to attach() the namespace of the package,
e.g., using the following:
pkg <- "myPackageName"
library(package=pkg, character.only=TRUE)
## --- Load the name space to allow testing of private functions ---
if (is.element(pkg, loadedNamespaces()))
attach(loadNamespace(pkg), name=paste("namespace", pkg, sep=":"),
pos=3)
Are there any pitfalls that I will find if I continue with this
approach? Or is there another better way?
