Lexical Scoping: eval(expr,envir=)
Hi R-listers, I am trying to better undertand what we would call "functional paradigm" use of S/R to better map my programming activities in other languages. This little function is aimed to create an object (at the end end, it would have it's own class): -- myObject =function(){ list( a=1, foo=function(b) { cat("b:",b)

[Wish]: Add "..." argument to library function
Hello, I would find it very usefull to have the ability to load packages with options. Consider for example the SciViews package Philippe and me are working on. When loading on Windows, it automatically loads the associated GUI executable. It should be convenient to have an option not to load the exe but still have an access to the R functions of the package. For that, I think a simple change

S3/S4 classes performance comparison
Hi R-devel, If you did read my survey on Rhelp about reporting, you may have seen that I am implementing a way to handle outputs for R (mainly target output destinations: xHTML and TeX). In fact: I does have something that works for basic objects, entirely done with S4 classes, with the results visible at: http://www.stat.ucl.ac.be/ROMA/sample.htm http://www.stat.ucl.ac.be/ROMA/sample.pdf To

S4 methods and polymorophism
Hello R Power Users, There is a rather large introduction you may skip to go directly to my question about S4 classes. I am working on some toy code to help me get in through S4 classes. Doing this homework, I have some questions about S4 classes. I have carefully read available help and some additional material such as Robert Gentleman's slides and special attention to "Programming

Hi UseRs, I don't want to die beeing idiot... I dont understand the different results between: cor() and cov2cov(cov()).

Differences between "$" and "[["
Hi, If I define the following list: > (l<-list("text-align"="right")) $"text-align" [1] "right" I know that I can't use l$text-align, as the parser will find a '-' operation. If I want (need) to use special names, as "text-align", I have to enclose it between "". So I can use: l$"text-align" or

Copyright issues question

The idea is to have R code that recreates within Excel the menus and some VBA part that handles data input and outputs (those beeing redirected to HTML and imported within Excel in a user-transparent way). Actualy, a first beyta version of this add-in

[survey] R for Reporting - the R Output MAnager (ROMA) project
Hi R UseRs, I am interested in providing Reporting abilities to R and have initiated a project called R Output MAnager (ROMA). My starting point was my R2HTML package which provides (rough) HTML exportations. I began with trying to mimic it for LaTeX but fastly did realize that it was a bad idea. Thus, I started again from scratch a new package and did spend a lot of time reading about this

special symobol / character
Hi all, Is it possible to add a permil (or per mille) symbol to an R plot (I couldn't find this symbol under demo(Hershey) or the plotmath information). In some ascii tables it is symbol no. 137. cheers, Matt. [[alternative HTML version deleted]]

Argument visible of addTaskCallback
Hello, I have a question about addTaskCallback It is said that the argument visible allows to know wether the result of the top-level evaluation was printed or not. Nevertheless, in the following example, I encountered a problem, as it seems not all printed objects are visible... Could someone tell me where is the tip? TIA

Suggestions for packages / help / index (long mail)
Hi R-users and developers, This month may have seen one of the biggest thread never seen on R-related mailing lists, the one about "GPL software" and "hidden costs" (at this day, thread is still open - and active!). Lot's of mails in this thread are not really relevant to the original mail, send by Philippe Grosjean. Nevertheless, most of the mails are of interest and

parsing a data file
Hi, I need to parse a data file (output of a measuring device) of the following format: BEGIN RECORD [first record data] RECORD [second record data] RECORD [third record data] END Line breaks can (and do ;-() occur anywhere. White space behaves very much like TeX, eg it is not important whether there are one or more spaces or linebreaks as long as there is one of them. It is a text file, not

R2HTML version 1.4-3
Hi useRs, I have uploaded on CRAN R2HTML version 1.4-3, which should be available soon for your favorite platform. For R 2.0.0, I had to rewrite some parts of the code so that it works. I did that quickly (maybe too), letting some bugs.

merge.list proposal
Hi R-devel, Today I was needing a way to "merge" two different lists (see the example for my definition of merge). I didn't find anything relevant using different search methods. So, here is my proposal to add a list method for "merge". Best wishes, Eric PS: AFAIK, there still is no place for code snipplets. I am not sure this mail doesn't suite R-devel. If not,

Once again in search of memory
Hello any R user, Working on R 1.8.1 or R 1.9 on Windows, 256 Mb RAM. I am trying to debug/correct/speedup the execution of one of our student's program. Basically, we perform simulations. R is launched with high memory-limits. One execution of the program requires nearly 200 Mbs and is OK the first time. Then, launching it again does strange things: seen from Windows manager, the RAM

c(recursive=TRUE)
Hi R users, I am currently using c(...,recursive=TRUE) to handle list-structured objects. This allows to represent something like: > l1 = list(level1=1,level2=list(sub1=1,sub2=2)) as: > (l1names = names(c(l1,recursive=TRUE))) [1] "level1" "level2.sub1" "level2.sub2" Then, one can use: > (l1names = sapply(l1names,FUN=function(element)
