Hello! I have the following problem. I would like to plot the hclust object "hcd" (bellow, at the end of the mail) with ticks at seq(0.05,0.25,by=0.05). I tried using the code plot(hcd) and plot(hcd,axes=FALSE) axis(2,seq(0.05,0.25,by=0.05)) In both cases, the resoult is the same, ticks at 0.05 and 0.25 are not printed. I tried changing the ylim argumet in plot, however I got a

Hello! I have writen some subrutines in Free-form Fortran. I would like to includ them in a package, which I would like to build on WinXP. I have all suggested tools/programs for bulding R packages on Windows (except latex). What is the best way of using these subrutines? Does sombody mybe know any translation tools for converting Free-form to fixed-form Fortran? Thanks for any suggestions,

Hello! I have two question that rose from trying to tacle the same problem in two differnet ways. What I want to do is to plot axes (only values or labels, no tick marks) in such a way that 'cex' can be very small, text can be perpendicular to the axis (as in axis(las=2) ) and the text is stil at the right position. Let me demonstrate with a small example:

Hello! I would like to convert rows of a matrix to a elements of a list. #For example, if I have mat<-matrix(1:100,ncol=5, nrow=20) #I can do: list<-apply(mat,1,list) list #however this is not quite what I want. To get what I want, I have to do: list<-lapply(list,function(x)x[[1]]) list Is there a faster way? Best regards, Ales Ziberna

Hello! I have a problem checking the package. Firstly, I do not know how to specify the package to check. I tied specify it by supplying the path and by runing the R CMD check in the directory of the package. In addition to that, I get an error bellow. Any suggestions on how to set TMPDIR would be greatly appriciated! C:\Ales\Statistika\Blocno modeliranje\dr\blockmodeling>R CMD check *

Does anybody know how to produce a East-European character "??" - "c with a v-shaped hat " in R (in text or plot)? I do know how to get "??,??" - "s,z, with a v-shaped hat", but not this one. Thanks in advance for any suggestions, Ales Ziberna P.S.: I am using Windows XP and R version 1.9.1 (details below) $platform [1]

Hi, It is my understanding that the eigenvectors of a circulant matrix are given as follows: 1,omega,omega^2,....,omega^{p-1} where the matrix has dimension given by p x p and omega is one of p complex roots of unity. (See Bellman for an excellent discussion on this). The matrix created by the attached row and obtained using the following commands indicates no imaginary parts for the

Hello! plot(1:10,main=expression(1 <= "m" <= 5)) The above command works perfectly in R 1.9.1 but returns an error in R 2.0.1 This is documented in NEWS for R 2.0.0 (or ONEWS in R 2.0.1) and it is said: o R no longer accepts associative use of relational operators. That is, 3 < 2 < 1 (which used to evalute as TRUE!) now causes a syntax error. If this

Hello! I was just wondering, why only one of my "Rd" files is converted in "chm" format (REGE) and the other are not when installing a package? The output from installing a package on WinXp is below. I tried to find more information about what "chm" format actually is, however have found none. Best regards and thaks for any replies, Ales Ziberna

Hi, I am a newbie with R, so I hope my question isn't too stupid. I am trying to generate dose-response curves using the "drfit" package. I have formatted my CSV files to the correct format, and have no trouble running drfit to get a summary of my data. The problem is that when I try to use "drplot" to graph my data I get an error. The message is: Error in

Dear expeRts! I'm thinking of buying a new computer and am considering dual-core processors, such as AMD Athlon64 X2. Since I'm not a computer expert, pleas forgive me if some of my questions are silly. First, am I correct that using a dual-core processor is (for R point of view) the same as using a computer with two processors? If that is true, the posts I found on the list imply that

A link in one of my help files does not work.

surely this not hard, but i can't figure it out. i'd like to overlay the results of two ecdf's. e.g. xx<--ecdf(x) and yy<--ecdf(y). i'd like to plot xx and yy on the same graph. thanks...mj [[alternative HTML version deleted]]

Thank you in advance. Now I want to make comparison of the different bandwidth h in a normal distribution graph. This is the table of bandwidth h: thumb rule (normal)--0.00205; thumb rule(Epanech.)--0.00452; Plug-in (normal)--0.0009; Plug-in(Epanech.)--0.002. this is the condition: N=1010 data sample is from normal distribution N(0,0.0077^2). The grid points are taken to be [-0.05,0.05] and

Dear All, I'm getting a error while trying to apply the BreastCancer dataset (package=mlbench) to kknn (package=kknn) that I don't understand as I'm new to R. The codes are as follow: rm = (list = ls()) library(mlbench) data(BreastCancer) library(kknn) BCancer = na.omit(BreastCancer) d = dim(BCancer)[1] i1 = seq(1, d, 2) i2 = seq(2, d, 2) t1 = BCancer[i1, ] t2 =

Hello! I have two functions. The first one prepares the arguments for the second one. What is the best way to put all resoults of the first one into the second one? I tried attach, however the object in the "main" enviorment have a priority over the ones in list. An example is at the end. Thanks in advance for any suggestions!

These errors are because not having glusternw assigned to the correct interface. Once you attach that these errors should go away. This has nothing to do with the problem you are seeing. sahina any idea about engine not showing the correct volume info ?
