similar to: help with bivariate density plot question

Dear R users: I have a dataset with two variables (>20000 observations, two samples from same subject) and I used "kernSur" from library(Genkern) to get a estimated bivariate density and corresponding plots as follows: new.data.normal<-data.normal[!is.na(data.normal[,2]),] x<-new.data.normal[,2] y<-new.data.normal[,3] op <- KernSur(x,y, xgridsize=50, ygridsize=50,

Is there code for bivariate kernel density estimation? For bivariate kernels there is kde2d in MASS kde2d.g in GRASS KernSur in GenKern (list probably incomplete) but none of them seems to accept a weight parameter (like density does since R 2.2.0) -- Erich Neuwirth, University of Vienna Faculty of Computer Science Computer Supported Didactics Working Group Visit our SunSITE at

Hi all I'm trying to create a three-dimensional wireframe-type plot, much like the screenshot shown at http://www.r-project.org/screenshots/volcano-persp.jpg In my case, I'm trying to show a density estimate of two-variable system, using the GenKern package. I've used the image() and contour() to create a nice shaded plot, but I've found a 3d plot is often easier for the

I am at my first steps with R... and I already notice that the console has a quite limited number of lines. Can anyone tell me how to visualise all the information, which is actually present? I only see the last part of the output, which obviosly exceeds the maximum number of rows in the console. Thank you very much for your help! Daniela [[alternative HTML version deleted]]

I've read in many places that R semantics are based on Scheme semantics. As a long-time Lisp user and implementor, I've tried to make this more precise, and this is what I've found so far. I've excluded trivial things that aren't basic semantic issues: support for arbitrary-precision integers; subscripting; general style; etc. I would appreciate corrections or additions from

I''m looking for a R function which can maximise this logliklihood function, under the constraits a>0 e b>0 f<-function(param){ a<-param[1] b <-param[2] log(prod)-(a*s2)-(b*s)-n*log(1-((0.5*b/sqrt(a))*(exp((b^2)/(4*a)))*((sqrt(pi ))*(1-pnorm(-b/(2*sqrt(a)), mean=0, sd=1)))))} I''ve tried maxlik constrOptim e donlp2 but without success. Thanks so

Dear All, I have a database of 200 observations named myD. In the dataframe there are a column named code (with codes varying from 1 to 77), a column named "prevalence" with some quantitative measurements are given and an column named Pr_mean, with no values. I would like to set a cycle to compute the average of prevalence values for each different code and store the averages under the

Hi, I am a non-expert user of R. I am essaying the fit of two different functions to my data, but I receive two different error messages. I suppose I have two different problems here... But, of which nature? In the first instance I did try with some different starting values for the parameters, but without success. If anyone could suggest a sensible way to proceed to solve these I would be

Hi all! I need your help. My server doesn't respond any more. Everything crashed. How can I find out if this is a bug or it is simply overloaded? I don't have much running, just KDE with about 10 programs on each of the 16 desktops, and a few background processes. This seems much, but I often have much more stuff running, and it is not even slow. It does respond when I ping it, but

Hi everybody! I was using the function pvals.fnc from package 'languageR' until April. I do not know which version. Yesterday I updated all my packages and tried to run my loop again. Now I get the following error message: error in pvals.fnc(mm, nsim = 1000) : MCMC sampling is not yet implemented in lme4_0.999375-27 for models with random correlation parameters I guess it?s because of

Hi guys, I'm trying to find the way to have Icecast installed on my website, so my listeners can go to http://www.radiodani.com:8000/stream and http://www.radiodani.com:8000/live and listen those streams. What should I do? Best regards, Daniela

Hi all! I'm having problems no end on my 4.8-STABLE box, and I hope you can help me. My processes get lots of signals (mostly 6, 10 and 11), and my kernel dumps core very often. I have the core dumps from the 4 latest crashes. See attachment for more info. Notice the common values for IdlePTD and initial pcb. Does this mean anything? There are other problems as well: 1) Some time ago KDE

Dear Sir/Madam; Would you please tell me what is the command that allows the estimation of the Kernel Density for some data. Thanks, Thami Rachidi [[alternative HTML version deleted]]

Hello, I'm very new in working with tcl/tk in R and have a problem which will probably sound silly to most of you. Here is the code I have problems with: readcelfiles <- function() { require(tcltk) tt <- tktoplevel() tkgrid(tklabel(tt,text="Choose a directory!")) OnOK <- function() { fileDir<-tclvalue(tkchooseDirectory()) data.raw <-

Hi list, I don't know if somebody has spent a lot of time debugging strange problems with if else positioning - the parser seems to recognize only the syntax bellow - this is the only way of making these pieces of code to work. As far as i'm concerned, no examples were available (it would be so awesome to have them in the introductory manual!) #Try to change the placement of the
