Hi, Would like to use to the hexbin package to plot a 2D hist - because it looks really _cool_. My problem is related to drawing a pdf hexbin graphic in series of other graphics. All other figures have a par(mar=c(3.2,3.2,1,1)). So the gplot.hexbin figure in this series looks a little alienated? Was trying a to specify the _mar_ using par, viewport, hexViewport etc. a little. My question. How

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.

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! 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 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.

This seems like a bug to me. Can someone verify this? First we define a function f that returns its second argument and lapply it to 1:2 using 9 as the second argument and all seems well. Note that "{" as a function does the same thing as f, as illustrated with f(1,9) and "{"(1,9); however, when we attempt to use "{" in the very same way we used f in lapply,

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

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

I have a vector with about 100.000 values representing a quite regular function (sinusoid like). I would like to find all local maxima of this function (should be about 4000).

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

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 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, 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 =

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, Please consider the following trivial example. In the sample code I first define a class MVCa using composition. This class contains a slot of type list. Next I define an inheritance relation using the function setIs -> MVCa "is a" list. Then I define a function printlength which prints the list-length which is defined for the type "list". If I call this function

I have been struggling with this problem for a while and I hope someone could help me. Or if someone could point me to a section in the manual I would be grateful. x <- "my" plot(1:10, main=expression(paste( x, Delta, "values" ))) Q : How do I get the title to say "my (triangle symbol) values" ?
