Re: [Rd] RFC: Add 'postinstall' hook to R CMD INSTALL ?
Isn't this what Type: Frontend is for? That gives you complete control
and would seem appropriate for both of your examples.

Why: 'R CMD INSTALL' is very good and very successful for CRAN packages. It
has solved most issues related to configure, make, ... etc by relying
on pre-computed and stored values.
CRAN is also very good as a mirror network to distribute content that
is easy to obtain by useRs.
So there are cases where I'd like to use CRAN / R CMD INSTALL to work
on non-package code. Two case are
i) littler which is easy to 'configure; make; make install' but
would want to live in $PREFIX/bin -- and I need to copy it there
ii) RCpp which is a library / glue code making live easier for C++
code to interface with R; also easy to configure but I'd then
libRcpp.{so,a} to be in $PREFIX/bin -- and I need to copy it
there
I hope not in 'bin' -- I am not sure if you mean $PREFIX/lib[64] or
$R_HOME/lib?
How: Similar to 'cleanup' we could have a script 'postinstall' in the
top-level directory, and if present, R would execute it.
As I'm the one with the itch, I'd be happy to work on code towards
implementing this -- but before I go overboard with it, I'd love to hear
comments, suggestions, questions, ... It is worthwhile? Is it feasible?
What did I overlook?

This is a rather general mechanism, designed for adding new front-ends
such as the *gnomeGUI* package. If a `configure' file is found in the
top-level directory of the package it is executed, and then if a
`Makefile' is found (often generated by `configure'), `make' is called.
If `R CMD INSTALL --clean' is used `make clean' is called. No other
action is taken.
I am talking about the need for 'other action' such as 'make install', say.
Are you suggesting I shoehorn what I want done into the main 'make' target ?
Yes. I don't see it as 'shoehorn' -- it is the install step.

Yes, cut&paste error. $PREFIX/lib is of course what I had in mind.

Indeed, most GNU software follow the convention of:
configure
make
make install
Surely `R CMD INSTALL` can be augmented to call `make install` as well
if the `Makefile` is found.

the second variable, being "+" or "-" is converted into zeros (0)
and treated as a numerical variable.

[Rd] Error Message (PR#11602)
Hello!
My Name is Jan Matthias and I am from Cologne University in Germany. I have=
problems with R , version 1.9.1.
I also use the package tcltk and follow the instructions from a command fil=
e which i will send with.
My problem is that the program always stops at the same step, showing diffe=
rent Error Messages sometimes. My Hope is that you have a suggestion what t=
he problem is and how to solve it. Because this is the first time I use thi=
s program and I have no idea anymore.
First an example log (I also got other Error messages as I wrote, but in th=
e same step! For example that the file could not be found):

I checked the file names, but still I got that message.
Additionally here the instructions I followed step by step:
turn on R 1.9.1.
load package tcltk

, col.names=3DF, row.names=3DF)
#atest.text.proc or func or comp says from which graph to get the data
I would be very thankful if you can give me any suggestion or help.
Kindly regards

[Rd] Posting Guide
People read the posting guide yet they are still unable to create an acceptable post. e.g. https://stat.ethz.ch/pipermail/r-help/2008-June/164092.html I think the problem is that the guide is not clear or concise enough. I suggest we add a summary at the beginning which gets to the heart of what a poster is expected to provide: Summary To maximize your change of getting a response when posting provide (1) commented, (2) minimal, (3) self-contained and (4) reproducible code. (This one line summary also appears at the end of each message to r-help.) "Self-contained" and "reproducible" mean that a responder can copy the questioner's code to the clipboard, paste it into their R session and see the same problem you as the questioner see. Note that dput(mydata) will display mydata in a reproducible way. Self-contained and reproducible are needed because: (1) Self-Effort. It shows that the questioner tried to solve the problem by themself first. (2) Test framework. Often the responder needs to play with the code a bit in order to respond or at least to give the best answer. They can't do that without a test framework that includes the data and the code to run it and its not fair to ask them to not only answer the question but also to come up with test data and to complete incomplete code. (3) Archives. Questions and answers go into the archives so they are not only for the benefit of of the questioner but also for the benefit of all future searchers of the archive. That means that its not finished if you have solved the problem for yourself. You still need to ensure that the thread has a complete solution. (For that reason its also important to give a meaningful subject to each post.) "Commented" and "minimal" also reduce the time it takes to understand the problem. Don't just dump your code as is into the message since you are just wasting your own time. Its not likely anyone will answer a message if the questioner has not taken the time to reduce it to its essential elements. Surprisingly, quite often understanding what the problem is takes the responder most of the time -- not solving the problem. Once the question is actually understood its often quite fast to answer. Thus in addition to posting it in a minimal form, comment on it sufficiently so that the responder knows what the code does and is intended to produce. It may be obvious to the questioner who is embroiled in the problem but that does not mean its obvious to others.

[Rd] Makevars or congiure for multi platforms
Dear all, As previously submitted, I wrote an extending pdf device to embed pop up text and web links. (Patches are available at http://pdf2.r-forge.r-project.org/patches) Now, I'm making a library version of the pdf device. However, with my skill, I'm not sure about writing Makevars or configure file for multi platforms. A following line in Makevars works on my mac, - PKG_CFLAGS=-I/Library/Frameworks/R.framework/PrivateHeaders -DHAVE_CONFIG_H - (Note that the PrivateHeaders directory contains Fileio.h and Defn.h) My question is, How do I write Makevars or congiure for Unix/Linux and Windows?

[Rd] Testing development code?
Hi, R Core Team: How do you test the latest changes to the core R code? Is it just "R CMD check"? Or do you use other tools, like the perl "prove" module? I ask, because I'm about to start developing routine testing for other (non-R) software, for which I can't do "R CMD check", and I'd like to know what you do. Thanks, Spencer Graves __ R-devel@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-devel

There are a few make targets, e.g. "make check", "make check-all", etc. See the Admin manual for a number of choices, or R_HOME/tests/README.

Re: [Rd] Posting Guide
I'd recommend either having two or three good examples of acceptable posts at the end of the posting guide or at least some hyperlinks to good examples. Two or three contrasting poor posts would also be helpful. If people can see a brief email with working code AND the ever-essential sessionInfo() output I think they will be more likely to compose a reasonable post. It's not rocket science when you see a few examples of good posts, but reading lines and lines of text describing a good post clearly is not getting through to many people. Steve McKinney -Original Message- From: [EMAIL PROTECTED] on behalf of Gabor Grothendieck Sent: Fri 6/6/2008 10:30 AM To: R Development List Subject: [Rd] Posting Guide People read the posting guide yet they are still unable to create an acceptable post. e.g. https://stat.ethz.ch/pipermail/r-help/2008-June/164092.html I think the problem is that the guide is not clear or concise enough. I suggest we add a summary at the beginning which gets to the heart of what a poster is expected to provide: Summary To maximize your change of getting a response when posting provide (1) commented, (2) minimal, (3) self-contained and (4) reproducible code. (This one line summary also appears at the end of each message to r-help.) "Self-contained" and "reproducible" mean that a responder can copy the questioner's code to the clipboard, paste it into their R session and see the same problem you as the questioner see. Note that dput(mydata) will display mydata in a reproducible way. Self-contained and reproducible are needed because: (1) Self-Effort. It shows that the questioner tried to solve the problem by themself first. (2) Test framework. Often the responder needs to play with the code a bit in order to respond or at least to give the best answer. They can't do that without a test framework that includes the data and the code to run it and its not fair to ask them to not only answer the question but also to come up with test data and to complete incomplete code. (3) Archives. Questions and answers go into the archives so they are not only for the benefit of of the questioner but also for the benefit of all future searchers of the archive. That means that its not finished if you have solved the problem for yourself. You still need to ensure that the thread has a complete solution. (For that reason its also important to give a meaningful subject to each post.) "Commented" and "minimal" also reduce the time it takes to understand the problem. Don't just dump your code as is into the message since you are just wasting your own time. Its not likely anyone will answer a message if the questioner has not taken the time to reduce it to its essential elements. Surprisingly, quite often understanding what the problem is takes the responder most of the time -- not solving the problem. Once the question is actually understood its often quite fast to answer. Thus in addition to posting it in a minimal form, comment on it sufficiently so that the responder knows what the code does and is intended to produce. It may be obvious to the questioner who is embroiled in the problem but that does not mean its obvious to others.

(Note that this is pretty arbitrary, but zero-length vectors always give an error so it is at least consistent.) What's happening is that R tries to run sd() on each column. The first column is coerced to a character, then var() says there are no non-missing observations. This has been discussed (and complained about) previously. (I'd like to add my vote for reversion of this behavior, because it screws up one of the examples in my soon-to-be-published book ... argh.) cheers Ben Bolker __ R-devel@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-devel
