similar to: Function _coerce_ in _setIs_ never entered (S4).

By reading the documentation for _setIs_ I noted that for the same object three different names are used. 1) the name of the first argument in the functions coerce and replace in setIs must be _obj_ (see example section or) setIs("MVCa","list",coerce=function(obj){obj@list},replace=function(obj,value){obj@list<-value}) 2) At the same time in the usage section:

Hello, am I using 'setIs' in the correct way in the subsequent (artifical) example? Do I have to specify explicit 'setAs' for 'list' and 'vector' or should this work automatically, since "getClass("List1")" states an explicit coerce also for these classes. I'm working with R 2.0.0 Patched (2004-10-06) on windows 2000. Thanks for your

Hi! I am installing R in non standard directory. ./configure --prefix=/non/standard/directory The installation works fine. But after starting R i get .libPaths() /usr/lib/R/library but they cant be there of course! Have I to set some additional switches during config? Eryk Dipl. bio-chem.

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, 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

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! >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, Is the ordering of the values returned something on what I can rely on, a form of a standard, that a function called unique in R (in futher versions) will return the uniq elements in order of they first occurcence. > x<-c(2,2,1,2) > unique(x) [1] 2 1 Its seems not to be the standard. E.g. matlab >> x=[2,2,1,2] x = 2 2 1 2 >> unique(x) ans =

Hi! I have installed the new R on windows. I wanted to reinstall the XML package. I am not able to find the XML.zip anymore. I am quite shure that they where a windows binary version.

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 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

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! 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.:
