Hi. I am a newbie to R. I need to do a courses projects with some manipulation lots of data record and some back-and-forth linear regression. I do not want to spend $100 for a SAS lincence, which professor used. So I decide to start to learn R to finish it. I am using R in Windows. I feel it is somehow works like mathemica. I try to write the work into a little program for future reference.

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

Dear R People: I will be teaching an undergraduate Design of Experiments class in the Spring Semester. It will be very much an applied course. My question, please: has anyone used R for a course like this, please? I've tried Rcmdr for a regression course and just plain command line for a time series course. Should I use Rcmdr, or teach them to use the command line, OR is there something

Dear members, Is there a way to turn a strwidth of a string into a number of lines that ist needed to display the string when using par(mar = c(?,4,4,2)) #### x = 1:5 names(x) = c("ZZZZZ","ZZZZZzzzzz","ZZZlllll","TTTTT","Zzhtsddfg" ) par(mfrow = c(1,2)) par(mar = c(8,4,4,2)) barplot(x, las = 3, main = "8 is to much") par(mar =

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, # #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.

I was told the X100P will have issues if installed on a line with a DSL connection. Is there a card that will work correctly on a DSL connection?

I'm installing syslinux on an embedded board that will only be reachable via boat+hike or helicopter. This will be a somewhat experimental platform, so I can't make a read-only filesystem on CF. What I'd like is to have two root filesystems on a CF card, one that is a read-only "fail-safe", and a 2nd that is the "normal" system I experiment with. What I'm

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 there, iam realy new to Linux and would consider me as total noob :) I was realy happy because i got Wc3 running, but now i'm getting this buffer underrun errors and sometimes the game crashs, but in 1 of 5 games my pc just freezes, i was wondering if this buffer underrun causes that or something else. "err:dsound:DSOUND_MixOne underrun on sound buffer 0x18f7a8" Anyways, my

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?

Hi, I've searched through the contributed packages and found conf.design which supports factorial design generation - is there any way to specify the values of the levels in the functions in this library? Currently the default for 2 level designs are the levels 0 and 1. Reason I ask is I'd like to create a Central Composite design and to do this by appending to a factorial design, it

Hi. I'm a student in a graduate program at Simon Fraser University in Canada. I am trying to run a simple screening experiment with some simulated data. I simply want to do an ANOVA of an experiemnt with 5 factors (4 have 2 levels, the last has 3 levels) and 48 runs (ie, full factorial). The thing is that I have multiple observations for each level combination (run). So, 1) How do I do
