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

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

Hi to all R users, I have just uploaded in CRAN R2HTML 1.3, latest update of the R2HTML package, so that it should soon be available for your favorite platform. CHANGELOG: - Fixed some user-contributed bugs. - More CSS styles are defined, so that it's possible to change the whole look-and-feel of outputs / Add some CSS sample files. - Added HTMLstem to produce a stem-and-leaf plot (as

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

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()). See this little example: > x=matrix(c(0.5,0.2,0.3,0.1,0.4,NA,0.7,0.2,0.6,0.1,0.4,0.9),ncol=3) > cov2cor(cov(x,use="pairwise.complete.obs")) [,1] [,2] [,3] [1,] 1.0000000 0.4653400 -0.1159542 [2,] 0.4653400 1.0000000

Hello R communauty, I have submitted to CRAN the package R2HTML. The purpose of this package is twice: - provide base HTML exportation functions. Basically, you will use them exactly as a print function (or a cat(...file=)). Thus, making dynamic HTML reports is possible. - making live HTML output with frames and command, which is very usefull for teaching purpose, as the student can keep a

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. Now, this is mere the good R 2.0 version, with some new functionalities: - HTML.matrix and HTML.data.frame now can use several new output options as they

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,

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

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)

Hi to the Devel list, I am at present developping a little Excel add-in that would consist into a translation of John Fox RCommander package. 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

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

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

Hi users, I am not sure to understand the help page about do.call. -- do.call(what, args) args: a _list_ of arguments to the function call. The 'names' attribute of 'args' gives the argument names. -- If we take the following sample data: > (tab=as.data.frame(table(factor(1:10)))) Var1 Freq 1 1 1 2 2 1 3 3 1 4 4 1 5 5

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
