Re: [Rd] Trouble building package using R in development

2013-01-18 Thread Hadley Wickham
 To what end is the --vanilla here? Writing R Extensions says that R CMD
 check (and R CMD build) are invoked via R --vanilla so that would seem
 redundant, although my experience from several hours working this
 through today suggests there is a difference between R --vanilla CMD
 check and R CMD check.

Maybe that's new? We've certainly had problems with R CMD reading user
startup files, which is why we starting using --vanilla.

[Rd] Trouble building package using R in development

2013-01-16 Thread Gavin Simpson
Dear List,

I'm having considerable trouble setting up my environment (Linux, Fedora
16, Bash) to build and check packages under R Under Development
(r61660). I'm doing this to better get a handle on difference in the
output from running checks on examples in one of my packages. Note I
compiled R Under Development myself

The problem I am now having is whenever I try to build my analogue
package using R Under Development, R complains about a dependency having
been built before R 3.0.0. I obviously don't have my environment
variables set correctly, but I don't see why or how R is finding my
daily-use package library; if anything I would have expected it to fail
with a missing dependency.

If I start Rdevel with --vanilla (to mimic Rdevel CMD build) I see:

 .libPaths()
[1] /home/gavin/R/devlibs /home/gavin/R/devel/build/library

the first entry there is because I have temporarily set R_LIBS to that
directory via export R_LIBS=/home/gavin/R/devlibs. From there we see I
have versions of the dependencies installed in this library and they are
built with 3.0.0:

 installed.packages(~/R/devlibs/)[, Built, drop = FALSE]
  Built  
analogue  3.0.0
ctv   3.0.0
permute   3.0.0
princurve 3.0.0
rgl   3.0.0
scatterplot3d 3.0.0
vegan 3.0.0

Note that there are no other versions of vegan inadvertently installed
to the build directory for R Under Development.

Following advice in Writing R Extensions I have also created
~/build.Renviron and ~/check.Renviron and as these are non-standard I
also followed the advice to set R_BUILD_ENVIRON and R_CHECK_ENVIRON
again temporarily via export:

$ cat $R_CHECK_ENVIRON
R_LIBS=/home/gavin/R/devlibs

$ cat $R_BUILD_ENVIRON
R_LIBS=/home/gavin/R/devlibs

Yet still I get errors building analogue:

Re: [Rd] Trouble building package using R in development

2013-01-16 Thread Gavin Simpson
As a follow-up, shortly after I clicked send I decided to do something
silly and rename my ~/.Renviron (which set R_LIBS too). Silly because
the Writing R Extensions (WRE) manual says that these startup files are
not read as R is invoked with --vanilla.

Once I renamed ~/.Renviron so it was not being read I was able to build
the package using R Under Development following the remaining
instructions in the WRE note [1]

So I do wonder if I have misunderstood the note in WRE or if there is
some other issue here? Starting R --vanilla with R Under Development
wasn't reading ~/.Renviron, and by renaming ~/.Renviron that I was able
to build the package indicates that this file was implicated in the
problem I described.

Is it intentional that R CMD build reads ~/.Renviron ? If it is, then
WRE should ideally clarify this or make it explicit. If it wasn't
supposed to be read, is there a bug here?

All the best,

Gavin

 To circumvent this, I check using:

In devtools, we take considerable care to match the R you're running
with the R you're checking in, so we also set the following
environmental variables:

env - c(
LC_ALL = C,
R_LIBS = paste(.libPaths(), collapse = .Platform$path.sep),
CYGWIN = nodosfilewarning,
R_TESTS = ,
NOT_CRAN = true,
TAR = auto_tar(),

and always run /path/to/current/R --vanilla CMD check ...
