Hi, does anybody know if it is possible to use an image (rather than text) to label the leaves of a dendrogram? I realize that this will not always lead to a useful on-screen display, but ideally I'd like to directly go from the dendrogram to a PDF and on-screen viewing is not to too important for me. Also, my trees are relatively small. Any pointers would be apreciated

Hi, I have a package for which I'm writing a vignette. The vignette looks fine as indicated by R CMD check. However after installing the package (in my personal R library location) doing vignette('rcdk') says Warning message: vignette 'rcdk' *not* found But I can see the PDF file located under rcdk/doc in the R library directory. The header of the Rnw file is %

Hi, I'm using rgl to generate a 3D surface plot and I'm struggling to get the lighting correct. Currently the surface gets plotted, but is very 'shiny'. On rotating the view, I get to see parts of the surface - but overall I don't see much detail because of the spotlight like lighting. I've played around with the specular, ambient and diffuse but I can't

Thanks in advance for any help. I am attempting to add points to a plot using the allEffects command in the effects package. When I try to add the points I get the following error message: Error in plot.xy(xy.coords(x, y), type = type, ...) : plot.new has not been called yet Strangely, using the code I've pasted below this has worked for me in the past however figuring out what has

Dear Colleagues: I would like to write a front end for a modeling function, but run into trouble when passing a weights argument. y <- 1:5 x <- c(1,3,2,5,4) w <- function(formula, ...) lm(formula, ...) lm(y ~ x, weights=c(1,1,1,2,2)) w(y ~ x) w(y ~ x, weights=c(1,1,1,2,2)) Error in eval(expr, envir, enclos) : ..1 used in an incorrect context, no ... to look in w <-

Christoph -- There was just a thread on this earlier this week. You can search in the archives for the title: "refitting lm() with same x, different y". (Actually, it doesn't turn up in the R site search yet, at least for me. But if you just go to the archive of recent messages, available through CRAN, you can search on refitting and find it. The original post was from William

I was obviously fascinated by Duncan's earlier message on RXLisp. I managed to build a working version of RXLisp for OS X, by some unabashed and rather uninformed hacking. I compiled XLISP-STAT using the gcc flags -fno-common and --no-cpp-precomp (not sure if they are necessary or not, they are part of an older hack). I "make libxlisp.so", using Duncan's replacement for the

Dear All, I have a data frame with n columns: X1, X2, ., Xn. Now I want to create a new column: if X1 = X2 = . = Xn, the value is 1; Otherwise, the value is 0. How to do that in a quick way instead of doing (n choose 2) comparisons? Thank you, Frank [[alternative HTML version deleted]]

A problem here getting winbind traffic to be encrypted using Kerberos. I have set up a test environment with a pair of servers (actually lxc containers): - samba server (ubuntu 16.04, stock samba 4.3.11) - client machine (ubuntu 16.04) joined with "net ads join" and winbind The client machine has the following in /etc/samba/smb.conf: ------- [global] #netbios name = client-ad
