Hi, I've been looking for Image Processing packages. Thresholding, Edge Filters, Dct, Segmentation, Restoration. I'm aware, that Octave, Matlab etc. would be a good address but then I'm missing the "statistical power" of R. Does anybody know of packages, projects etc. Comments on wether the use of R for such matters is useful are welcome. Greetings Thomas Kaliwe

#Hi, # #somebody knows how to remove the outer box around a wireframe and reduce the height # # test = data.frame(expand.grid(c(1:10), c(1:10))) z = test[,1] + test[,2] test = cbind(test, z) names(test) = c("x", "y", "z") require(lattice) wireframe(z ~ x*y, data = test, par.box = c(col = "transparent") ) #not this one but the remaining outer box.

Dear listmembers, I would like to define a class with a slot that takes either an object of class aov or NULL. I have been reading "S4 Classes in 15 pages more or less" and "Lecture: S4 classes and methods" #First I tried with list and NULL setClass(listOrNULL") setIs("list", "listOrNULL") setIs("NULL", "listOrNULL") #doesn't

Hello, I want to import R-output via Rserve to Java, especially for the function ctree from the package party. Rserve is working properly. Yet, I only get the predictions with the Java code try{ RConnection c = new RConnection(); ... c.voidEval("modell <- ctree(...)"); REXP y = c.eval("nodes(modell,1)[[1]]$prediction"); ...

Hi, I'm sorry for this not being related to R but I think this is a good place to ask. I'm looking for DOE examples(experiments) that can be done at home or in class, such as Paper Helicopter, Paper Towel etc.. I'm thankful for any comment. Thomas [[alternative HTML version deleted]]

Hi, I'm trying to evaluate a character vector within pnorm. I have a vector with values and names x = c(2,3) names(x) = c("mean", "sd") so that i tried the following temp = paste(names(x), x, sep = "=") #gives #> temp #[1] "mean=2" "sd=3" #Problem is that both values 2 and 3 are taken as values for the mean argument in pnorm pnorm(0,

Hi, Using tab spaces in mtext e.g. > mtext("\t") little squares are plotted. Is there a way to use "\t" without getting squares displayed? Thanks Thomas [[alternative HTML version deleted]]

Hi, I have the following problem. Calling wireframe within a loop results into an empty window(s) #generate some data temp = expand.grid(A = 1:3,B = 1:3) temp = cbind(temp, y1 = rnorm(9)) temp = cbind(temp, y2 = runif(9)) #plot y1 and y2 in two different windows for(i in 1:2) { wireframe(y1 ~ A*B, temp, shade =T) windows() wireframe(y2 ~ A*B, temp, shade =T) } #However, calling it twice

How do you calculate T and P statistics (T- test) in R? Is there a package out there that can do these calculations?

Hello everyone ! In my pass I inspect the penultimate instruction from every basic block in runOnFunction(). I am interested in ICMP instructions only. if(BB->size()>1) if(last->getPrevNode()) { previous = last->getPrevNode(); ok=1; } I want to get the operands of previous, which is of type Instruction*. Due tests based on getNumOperands, ICMP has 2 (as

Hi Duncan, Thank you for your response! Now it works. But I have another problem: Do you know how can I iterate through a Value*? For instance, I have : Instruction *I1; // I take only I1 that are ICmp errs()<<"\n "<<*I1->getOperand(0)<<" \n"; // %3 = load i32* %c, align 4 As expected. Now I want to get %c from the previous to use "%c" in

In the plotcorr() function in the ellipse package, I want to position things differently depending on the size of the labels. I can use strwidth to find out the length of the labels, but only when there's a plot window open: it won't open one. Question: What function call says: make sure there's a window open (i.e. do what plot() does before it starts plotting)? I don't think

Dear plotting experts, I need to determine the width of a string before plotting it to the current device because I want to adjust `mai' to have the necessary space available. It seems to me that this is an "hen and egg" problem: R> a <- "test" R> strwidth(a) Error in strwidth(a) : plot.new has not been called yet # ok, I need an open device R> plot(1:2,

In platform i386-pc-linux-gnu arch i386 os linux-gnu system i386, linux-gnu status major 2 minor 0.1 year 2004 month 11 day 15 language R I'm getting an error when using strwidth after a lattice graphic is drawn: library(lattice) xyplot(runif(20) ~ runif(20)) strwidth('xxx') Error in strwidth("xxx") : invalid graphics state Any help

Hi, This is not a bug, but an enhancement suggestion. "strwidth" only gives the width of the text according to the x-axis user coordinates, and similarly for "strheight". Even if the par setting "srt" is changed to rotate the text, the resulting width (resp. height) is in terms of the non-rotated text. Currently, if I want to know how much space to leave for

Hi! Is there a way to get the string width of the bold typefaces? like: strwidth("text", family = "serif", font = 2). Thanks Roland

Dear List Members, I was wondering if there's a way to include an image in a .Rd file, something like \img{} In http://cran.r-project.org/doc/manuals/R-exts.html#Documenting-packages nothing's mentioned regarding images (besides the image of the workspace) Is there a way to include an image?

Dear All, I would like to plot text with a box around it. I used strwidth and strheight to compute the size of the box which is plotted with rect: z <- rnorm(10) # horizontal text works plot(rnorm(10)) x1 <- 5 y1 <- 0 label <- "Label" cha <- paste(" ", label, " ", sep = "") xh <- strwidth(cha, cex = par("cex")) yh <-

R users, I have a problem with function strwidth in 2.7.1. I'm trying to set the plot margins in a way that horizontal column labels will fit to the graph. tmp.t is a list of data.frame objects. This code works well in 2.6.0. ...snip.. library(gplots) for (i in names(tmp.t)) { bmp(filename=paste(i, "_", Sys.Date(), ".bmp", sep=""), width=1038,
