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! 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! 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! 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.:

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.

Is there a library that is able for example to 1. merge 2 dataframes by row eg.: rbind(dataframe1, dataframe2):data.frame 2. delete a column from a dataframe del(dataframe, colname) or del(dataframe, colindex= 1):data.frame? 3. Select lines from a dataframe by a specific function ? select(dataframe, func=small(x){x<1}, colindex=3): data.frame? 4. converting all double columns of a data.frame

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

Hi, While checking the package I am getting all the time the following complain about the function: Undocumented S4 methods: generic coerce and siglist matrix,Massvector I have not defined the function nowhere in the R files. My gues is that this has something to do with the following definition of the setAs function. setAs("matrix","Massvector" ,def=

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

Hi, How to add values to an array at any position. Asking because of the following: e.g. y<-c(0.1,NaN,0.2,NaN) #or data frame x<-na.omit(y) take some columns from x and do some computation with functions which do not allow NaN 's. After the computing add NaN's at positions stored in attr(x,"na.action") of the result vector. /E -- Dipl. bio-chem. Witold Eryk

Dear developers. Have spend just 1 h searching for a bug in a new version of a new version of a package. I was getting a segfault all the time. "Funny" thing - there was no error neither in the S nor in the C code. To solve the problem I had to delete the .Rdata file! What I observed. If the .Rdata file was generated while a previous release of a package was installed in the

Hi! I encountered some things trying to build own packages under Windows 2000 for which i found no answer in the documentation. First. 1. I do not found the rcmd.exe in the bin directory of R_HOME. I installed R using the setup.exe 2. I updated the R intatllation with one of the zip files. (rw1041sp.zip) now i had the rcmd.exe in the bin. 3. I do not found any hint in the docu that perl is
