Bioconductor version 3.3 (BiocInstaller 1.21.4), ?biocLite for help
Bioconductor does not yet support R version 3.4.0

The release of Bioconductor on May 4 and the next release in the fall will both be based on the R-3.3.* series, because that is the version of R that users (rather than 'developers') will have. The spring release next year is the first that will use R-devel. Bioconductor will not support (has no need to support) R-devel again until after the fall release, when the Bioc-devel branch will use R-devel. So for the next six months there is no sense (or support) for Bioconductor packages to use features that are only available in R-devel.

Michael has ported this new feature to the R-3-3-0 branch

R-3-3-branch$ svn log -r70426

r70426 | lawrence | 2016-04-05 17:06:10 -0400 (Tue, 05 Apr 2016) | 2 lines

------------------------------------------------------------------------

so that with a sufficiently new R you can use this functionality. The build systems will eventually be updated to an appropriately recent version of R from the 3-3-branch.

Also, just btw, there are two other places where arbitrary R
code
can
be evaluated in the NAMESPACE, but no one has abused them
yet.
as
far
as I know. The first argument to if() and the .fixes argument
to
useDynLib(). The latter sets the precedent for the except=
behavior.
Although someone forgot to document it, you can do
.fixes=c("prefix",
"suffix") to both prefix and suffix incoming native symbols.
Currently, the documentation only mentions prefixing. Not
sure
when
suffixing would be desirable.

Yes, it's arbitrary R code that is evaluated, so paste0()

You're right that it's a big door and could let people do
weird
things. Do you foresee a problem with that?


Opening such a big door raises many questions. In addition
to
allowing
people do weird/crazy things (like putting calls to
library()
or requireNamespace() etc... in them), NAMESPACE files with
arbitrary
R code in them become more complicated to maintain and the
tools
for
parsing/processing them also become more complicated to
write
and
maintain.

Now we have a new category of errors that can happen at
package
installation time: errors triggered by the evaluation of
the R
expressions embedded in the NAMESPACE file. Hopefully 'R CMD
INSTALL'
will report something that can be understood by mere mortals
when
this
happens.

Once you create the feeling that a NAMESPACE file is just a
file
that contains arbitrary R code then people expect import(),
export()
etc.. to be ordinary R functions with a man page (being able
to
do
?import would not hurt actually) and they'll naturally try
to
do
things like

   unwanted_foo_symbols <- ... long and complicated
expression
                               eventually calling
user-defined
helper
                               functions located in the
NAMESPACE
file
...
   import(foo, except=unwanted_foo_symbols)

Can't blame them for that. But is this the kind of things
that
we're
ready to see in NAMESPACE files?

Also once you've open that door, people will naturally
wonder
why
they
can use an R expression in the 'except' part of import( ,
except=)
but
not elsewhere e.g. in

   import(foo, only=paste0("bar", 1:10))

as a more elegant way of doing importFrom(foo, bar1, bar2,
...,
bar10).
This dissymmetry between the syntax of "import only this"
and
"import
all except this" feels very arbitrary. If you don't support
the
import( , only=) syntax, people might legitimately ask
things
like

   do.call(importFrom, c(list("foo"), as.list(paste0("bar",
1:10))))

to work. Again, can't blame them for that. But do we want
this
kind
of
things to work? I'm worried debugging NAMESPACE files would
become a
full-time job...

I guess one could have implemented NAMESPACE parsing by
evaluating
the
code in an environment (inheriting from the base namespace)
where
import(), export(), etc, were defined. Maybe there's a good
reason
why
it was not implemented that way.


I'm sure there is ;-)

mmh... so R expressions with calls to base functions like
base::c()
are
making their way in the NAMESPACE file. That's opening a
big
door.
Does
that mean that we'll be able to do things like:

import(foo, except=paste0("bar", 1:10))

Or maybe c(bar, baz) in your above example is just an
arbitrary
syntax
that just happens to look like an R expression but won't
be
evaluated
as such?

Fair enough. Not really intuitive that excludeImport

though.
Maybe
having

I will think about adding an excludeImport() or

What about having something like an
importPatternFrom()
directive
similar to the exportPattern() directive and have
these

support some of the grep() toggles like
'ignore.case',
'fixed',
'invert' etc... ?

Then Julie could just do:

importPatternFrom(hash, "^values$", invert=TRUE)
