Hi to all R/S gurus, I am developping a library to export R/S objects to HTML (there was developments of this library past year, by myself and Mathieu Ros, but we never finished it). For that, I wrote HTML.* functions handled by the generic method HTML. At this step, allmost all objects exportations are possible: matrix, atomic, data.frame, functions and even plots... but I still don't

Dear all, Some days ago, I asked to the list a way to recursively handle lists objects, so that on can apply a function only on terminal nodes. Thank you for all the answers. You will find here a little summary of answers with comments: - lapply allows the user to apply a function on all the items of a list, supposing this is a list with a unique depth (like:

Hello R-users, I need to create a vector inserting an 1 after each value of another vector. For example: vec1<-c(2,3,4) I need to create a vector with the values 2,1,3,1,4 Does anyone know how create this vector without loops (vec1 could have 1000 elements) Thank you, Juan -.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.- r-help mailing list -- Read

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)

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 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

Hello, I am actually developping a libary under S+/NT in which I do modify the .Program. Is there any equivalent in R? (the .Program is the command line parser, ie the function which is called when you press enter and pass the commmand line to the internal program) TIA Eric ?-----------------------?--------------------------------------------------? | Eric Lecoutre | DEA de

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 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

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 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

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

I was wondering whether somebody has developed a set of Textpad macro that work with R the same way as WinEdt does. I use Textpad for almost everything (programming, creating LaTex docs, etc.), it will be nice if I can use it as my R program editor. Or maybe someone can tell me how that kind of macro works so that I can develop my own macros. Thank you! Best, Shige Song Department of Sociology,

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 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]]

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

Dear list, Here's a little problem I already solved with my own coding style, but I feel there is a more efficient and cleaner way to write it, but had no success finding the "clever" solution. I want to produce a factor from a subset of the combination of two vectors. I have the vectors a et b in a data-frame : > df <- expand.grid(a=c(0, 5, 10, 25, 50), b=c(0, 25, 50,

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
