Hi! I would like to give my objects functions like "subset", "union", et cetera and name it also in this way. But this functions names are already used in the base package and they are not generic. I am right in that if they would be generic then i still can use the neat names with my objects? I have the impression that there are more and more packages are going to be

Hi! How to generate a empty string of a precise length without using a loop? I need a empty string (char **) to pass it with .C function to a c dll. The c routine writes the result into the string.

Hi! How can i send http Post and Get messages to a Web server from within R? Has anybody implemented a function like? form(action="http://big.thing.inf/cgi-bin/answer.pl",list(test="my",something="there"),method="POST"). Has anyone a package with a similar functionality like the LWP and HTTP::Request::Common packages in Perl? Or has anybody a function that

Hi! Are there scripts or packages for generating Rd files out of "S3" code on cran? Has any one written such scripts (e.g. in Perl?) and are willing to share them? Thanks in advance. Eryk.

Hi! Is there a way to get a subset of a list? I looking for some function like the function available for arrays and dataframe. x<-1:10 x[-c(1,2)] for arrays or x<-data.frame(a=1,b=2) subset(x,select=-a) But one for a list x<-list(a=1,a=2) subset(x,select=-a) The second problem i have are that i want to store parmeters to the plot.default function in a list. eg.:

hello I am returning to some libraries that I had previously customised by amongst other things adding additional functions. I had simply typed these new functions into the file in library/R/thelibrary. These however do not seem to be loaded now as they previously were under older versions of R. What's changed and what do i need to do? Thanks Stephen

Hi! On the cran "package source" page, to each package there are the "reference manual" in pdf format with a nice title page. I observed that during the R CMD check pkg a pkg-manual.div are generated in the pgk.Rcheck directory. But the nice title page are missing. During the package build and install no div files are produced. Which opitions I have to pass during the build

Hi! I am trying to calculate a dissimilarity matrix using daisy. The matrix vectver is binary as i test with: > levels(as.factor(vectver)) [1] "0" "1" But the call to daisy gives me the following error message.: > dfl1 <- daisy(vectver, type = list(asymm = c(1:length(vectver[,1])))) Error in daisy(vectver, type = list(asymm = c(1:length(vectver[, 1])))) : at least

Hi! I am installing R in non standard directory. ./configure --prefix=/non/standard/directory The installation works fine.

Hi! Like to write quite a lot (ca 100) of objects from my envirovment with save. The names of the objects are in a list nam. nam<-dir() nam<-grep("E",nam,value=T) length(nam) 20 for(x in nam) { #reads the objects and assigns the names. assign(x,simFromEmboss(Simmatrix(),x)) nnam<-paste(x,".rda",sep="") print(nnam) save(x,file=nnam) } I knew that

Hi! I guess that it cant work. but maybee I am wrong. I would like to define a function rbind. > rbind function (..., deparse.level = 1) { which works only for objects of class Myclass Is it possible to use something like setMethod("rbind",signature(...="Myclass",deparse.level="numeric") This gives an error. Or should I use rbind.Myclass Eryk. Dipl. bio-chem.

Hi! Would like to plot two image plots with color scale (like levelplot (lattice) implements) in one graphic device. Tried to plot 2 levelplot's (lattice) (the data has not much in common) in one graphics device by setting par(mfrwo=c(2,1)) which does not work. Is there a way to force levelplot to use only a half of the graphic device? Is there a function like image which provides the color

Hallo! I would like that the internal package functions does not appear in the documentation. I placed they names as aliases in the file nameofmypackage-internal.Rd as advised. After R CMD check (which runs neatly) they are still listed in 00Index.html. Is there no way to hide internal functions from the doc? Have I overlook something? Sincerely Eryk. Dipl. bio-chem.

Hi! >library(cluster) In this lib a function called silhoutte.default is defined than on the R prompt it type >silhouette.default Error: Object "silhouette.default" not found R1.9.0 The same error are at R1.8.1 And I knew that a function silhoutte.default are present.

Hi, I clustered a distance matrix and would like to draw it using plot.hclust or plot.dendrogram. The dendrogram is not informative because I have a few extremely small dissimilarities in the distance matrix (e.g. 0), but most of the other distances are in the range 1e10+-5000. I would like to show the tree only for the height of 1e10+-5000 but unfortunately their are no parameter like

Dear All, using R is noticed that I would benefit by going back to the books and "refresh" my linear algebra and calculus. Has anybody suggestions on which books are better as reference on the two these two topics? I was thinking to get Lang's "A First Course in Calculus", but I I have no idea what could be a good one for linear algebra. Something detailed and clear

Dear, I'm looking for some examples on OO programming in R. I have the programming manual with explanation on UseMethod and NextMethod but I miss some practical examples to get me going (I hope). I searched the web but could not find a good independent tutorial on this. Any suggestions are welcome, Kris -- ------------------------------------------------------------------------
