Re: [R] What makes R different from other programming languages?
Hi. Em Ter 21 Ago 2012, Mark Dalphin escreveu: I guess the other aspect which I take the most time to describe to any programmer from other more traditional languages is the working with vectors. To use R effectively, you must move data in large chunks; the standard paradigm of looping over the data is the fastest way to write a slow program. That's what makes R kind of hybrid: both procedural and declarative. Declaring objects and its predicates and have all fully and efficiently processed without programming every single step may be shocking for those who only know the 'procedural way'. Except for the experience with SQL with which we do not write 'SQL programs', most programmers (including amateur programmers) never had contact with the declarative programming paradigm. Many may have never heard of Prolog, for instance.

A linguist that is a good friend once observed that language is both expression and a modeller of how we think. No matter in which extent each one is true, the 'expression' property has some compelling evidence in support: it has been demonstrated that human babies generate the same words and phonemes without regard to the culture of their parents, that is, everywhere babies generate a common babies' language. In everyday life, each profession has its technical jargon and even a peculiar slang (not to mention the set of jokes :-) ). In computing, it is remarkable that different languages developed by the same person are extremely similar: Nicklaus Wirth's Pascal and Modula 2 have almost identical syntax, use the same function naming and calling conventions, etc. From this angle, it does not look strange that R is peculiar and can even be regarded as a new, more free paradigm with regard to control structures and yet hold all the features of a structured language. And although a procedural language there are some instances in which R resembles a declarative language (IMHO, this could be extended, enhanced :-D). -- Alexandre Aguiar, MD SCT SPS Consultoria -- Sent from my tablet.

[R] heavy processing during R_init_XXXXX()
Hi. Need some advice. I have to load a library during R_init_X() with dlopen(). The library file is 23 megabytes long and loads several other libraries. Everything happens during dlopen() execution, out of control, and takes around 1 second on first load in a quadcore. Besides, due to security reasons, a hash of the library file is going to be computed. Still do not know how long it will take. Questions. Is 1 second acceptable for R? Slower machines may take a lot longer to return from R_init_X(). Does R_init_X() have to return soon or call R_CheckUserInterrupt()? Or is it somehow free from this R need? Is it safe to load the second library and compute the hash within other threads so R_init_X goes on? If some function of my extension library is called it can call R_CheckUserInterrupt() if and while the threads do not end. If such use of threads is safe inside R, is there a package that does it? Any tips? Flags currently sent to dlopen are (RTLD_LAZY | RTLD_LOCAL). Revolving the R sources could not find the flags R uses. Does any of you know for sure the flags used to load extensions with loadLibrary()? Looking into computeDLOpenFlag() did not answer the question. Is there a recommended flags set in this situation? Aparently dlopen() flags LM_ID_BASE and RTLD_GROUP (their use sounds wise) are not defined in Linux. Is this correct or I missed something?

Re: [R] [Rd] example package for devel newcomers
Em Segunda 01 Agosto 2011, você escreveu: Is there a preferred language you would like to use in your package development? I randomly downloaded packages until I found some that helped me along my way, and might be able to help you pick one. If you are just looking at building a package of R functions and data you have developed, possibly the following example will get you started till you feel comfortable with the Writing R Extensions documentation (http://cran.r-project.org/doc/manuals/R-exts.pdf): Dan, your message is cool. Well, here is what my project is about: it is a package to embed php into R. Named Rphp for now. It is mostly done from scratch. I have loved R-exts.pdf. Great stuff. Why embed php into R? My primary purpose is to use web content management systems (WCMS) ready and extensively tested code from R cgi scripts. Someone more experienced with php might think of other uses. My approach is RAD(ical) and innovative (IMextremelyHO :-D) because: a) *any* php based WCMS can be used from R code with no php or html coding; b) output fully compliant with the website appearance; c) WCMS automatic upgrades and interfaces changes (skins or themes) will be so unlikey to cause need for maintenance in R cgi scripts; d) R cgi scripts will not demand changes in php code; e) the builtin php session support obviates the need for any special session coding by R (likely non-web) programmers; f) potential for improved analysis of web databases and even of systems surveillance tasks. During my explorations of the R interface for extensions and the time spent in this tiny project, some questions emerged. 1. my code uses no recursion but I do not really know what is inside php code. Stack size could be a concern. Has any of you there ever needed to allocate a new stack for a package? Is it better to wait for complaints (if anyone ever would like to try this package...)? 2. can R_registerRoutines be called more than once within the same library (the same DllInfo data) so that it can reconfigure itself on the fly? 3. Is it safe (I guess it is) to re-export a function pointer retrieved with R_GetCCallable? 4. when loading a second library (in this case libphp5.so) is it better to put it in the package library directory and load it using the 'char *path' member of DllInfo? Using a second library has implications: a) a given R setup can be limited to the user space without root access; b) in the case of desktops where someone might use Rphp, most systems do not have libphp5.so installed by default and installing it frequently means to install apache and all (many) related packages; c) many sysadmins do not have root access but can compile their own php version; d) building the libphp5.so may not be an easy task for many. 5. Similar to 3, is it safe to export functions of the second library? libphp5.so will not be registered to R and has some interesting functions that can be exported directly or as pointers within Rphp library. A stub function can be used. 6. related to 4, with the many machine architectures and operating systems around I think it is neither desirable nor feasible to distribute precompiled libphp5.so versions; the package itself can download (wget and curl are everywhere) and compile php. Compiling php is not a lengthy task (6m12.9s in my quadcore desktop) but is a lot tricky and demands several development packages not installed by default in desktop systems. Their installations would require root access. What is the suggested approach to deploy libphp5.so? 7. I do not know how to produce a version for windows if requested. I have only an old MSC++ 97 and lcc (current) and have xp in a virtual box. This concern includes php. Can I get help regarding windows in this list? It might mean actual work: adapting code, compiling, packaging, etc. Not sure what is needed. 8. system safety does not seem a concern regarding this use of php, but... Any suggestions? I guess some manual steps will be necessary because of potential security breaches related to the use of a second library. Patching php to produce a special build to be used as the package library would not be a trivial task and would demand updates at every new php version. Something I can't assure I can do. And would have to distribute the whole php source code: still have to study php licensing scheme. BTW, I copied Rdynpriv.h by hand to my include path to get access to 'struct _DllInfo' definition. The R install process did not copy this file. Am I doing something wrong here? Sorry for the lengthy message.

[R] damaged text output of legend() and plot()
Hi, System: laptop, Turion 64, Kubuntu Linux, Xorg X server 1.4.0.90, KDE 3.5.9, R 2.7.2 compiled with default settings. I recently changed my laptop setup to get better font rendering in the LCD monitor. Some subpixel stuff that limits quality of bitmaped fonts. When generating jpegs with R the text output of legend() looks blurred. This affects both legend() and plot() in pngs. Attached 2 samples. I used family=sans. The same script produces normal output in my desktop where the monitor is a CRT. Funtion text() seems normal. Is there a workaround for that?

[R] R as shelll script
Hi, I have devised some applications of R as a scripting shell language and started using it flawlessly a few months ago. Never minded publishing it because it looked so obvious. However, a search in the archives revealed there is no recent easy-to-use method proposed. The latest reference I found is from 2006 (http://finzi.psych.upenn.edu/R/Rhelp02a/archive/81124.html) and even a c wrapper has been proposed (http://kavaro.fi/mediawiki/index.php/Using_R_from_the_shell). So, here it goes an exceedingly simple example of my simple solution that works pretty well: #!/usr/local/bin/Rscript --vanilla update.packages(ask=F, repos=http://cran.spsconsultoria.com;) # no need for calls to quit() Now just chmod this properly (at least 700 is advisable) and you have an executable that can be run directly from the command line. The --vanilla option is important to avoid dissemination of .History and .Rdata files in the system. But one can replace for another set of options to allow the load of .Rprofile, for instance (by using --no-save --no-restore --no-site-file --no-environ instead). This has worked to me under several flavors of Linux and R since 2.2 or 2.4, not sure, do not remember (it must be that german guy the doctor said I can't remove from my mind :-). Thanx for the existance of this list.
