In the documentation the closed thing I see to an explanation of this is that ?detach says "Unloading some namespaces has undesirable side effects" Can anyone explain why unloading tseries will load zoo? I don't think this behavior is specific to tseries, it's just an example. I realize one would not usually unload something that is not loaded, but I would expect it to do

I have a package (TSdbi) which provides end user functions that I export, and several utilities for plugin packages (e.g. TSMySQL) that I do not export because I do not intend them to be exposed to end users. I call these from the plugin packages using TSdbi::: but that now produces a note in the checks: * checking dependencies in R code ... NOTE Namespace imported from by a ?:::? call:

Is there a good strategy for testing examples which should not be run by default? For instance, I have examples which get data from the Internet. If I wrap them in try() then they can be skipped if the Internet is not available, but may not be tested in cases when I would like to know about the failure. (Not to mention that the example syntax is ugly.) If I mark them \dontrun or \donttest

...ace("tseries"), it calls getNamespace("tseries"), which has the side effect of loading that package (and its dependencies). One way to work around this is to check loadedNamespaces() before you try to unload a package. -Winston On Thu, Jan 8, 2015 at 9:45 AM, Paul Gilbert <pgilbert902 at gmail.com> wrote: > In the documentation the closed thing I see to an explanation of this is > that ?detach says "Unloading some namespaces has undesirable side effects" > > Can anyone explain why unloading tseries will load zoo?

Am I correct in thinking that the ?SystemRequirements? field in a package DESCRIPTION file is purely descriptive, there are no standard elements that can be extracted by parsing it and used automatically? This field does not seem to be widely used, even for some obvious cases like backend database driver requirements, perl, perl modules, etc. It might help to have a list of possibilities. Some

hi, r developers, I am now working on a R function/package to handling online request with username and token/password. For security reasons, it's not so safe to store the username & token in persistent variables, since they'll be saved to disk when users save their workspace. Is there a secure way in R to handle the online password management? I have searched it online but didn't

I am trying to follow directions at http://cran.r-project.org/doc/manuals/r-patched/R-exts.html#Suggested-packages regarding handling suggested packages with requireNamespace() rather than require(), and I have some questions. 1/ When I do requireNamespace() in a function is the loading of the namespace only effective within the function? 2/ At the link above in the manual it says "Note

I think improvements in the RNG is a situation where backward compatibility is not really going to be lost, because people can specify the old generator, they just will not get it by default. My opinion is that the default needs to generally be the best option

I wonder how useful a (set of?) "time machine" functions which look up /infer things like this based on a date would be. Could ease the pain of changes generally, though not remove it completely. ~G On Wed, Aug 31, 2016 at 5:45 PM, Paul Gilbert <pgilbert902 at gmail.com> wrote: > > > On 08/30/2016 06:29 PM, Duncan Murdoch wrote: > >> I don't see evidence of a bug.
