similar to: Re: Plotting bivariate normal distributions.

Hi, I've used the Mathematica to produce 3D graphics, contour plots of a bivariate normal distribution Now I want make these graphics in R, but i do not know how. I would like to: - Plot a 3D graph for some different variance matrix - Plot the contour plots - Find and try to plot (in the 3d graph ou contour plot) the (1-a)% confidence region based in a chi-square(a) with the degrees of

Using R 2.5.1 on Windows XP Professional, and PBSmapping package version 2.51, I have encountered some behavior which puzzles me. I am including the package's listed maintainer on this email but also seek the thoughts of the R-help community. I have a set of EventData, which I want to plot as points, and to color the points according to some criterion. It turns out that some of my

I'm trying to use the clim.pact package but I cannot find the descritions of "map object or "field object". For example, according to the man page of function "map": " Description Produces maps. Usage map(x,y=NULL,col="black",lwd=1,lty=1,sym=TRUE, plot=TRUE,inv.col=FALSE) Arguments x A map object. ... " and according to the man page of

Hi, I am new to this mailing list. Didn`t find the answer in the archives. But I guess, there are people out there, who know the solution: In an automatic script, I want to produce simple plots. First I prefer pdf, because of scalability and standardization. But when I have too many datapoints (say 300.000) the viewing and printing is very, very slow. So I decided to take some bitmapped format

Hi, Are there some texts about time series that teatches it with R? And site 'bout time series "for dummies" , can anyone indicate them for me? thanks a lot Rafael Bertola Undergraduate in Statistics at UNICAMP - Brasil -------------------------------------------------- --------------------------------------------------

I'm looking for data to use with nonparametrics exploration technics. I'm a undergraduate student in statistics at the Unicamp (Brazil), and i've to make a project (with orientation of a professor). I choose nonparametrics statistics to make the project. But in this project i must have to use a databank and present analisys. So, if somebody give me indications where i can find

I?ve a data set and i want fit a kernel density estimate to the data. but using the k-nearest neighbour method. How i do this with R. thanks -- bertola at fastmail.fm --

Hello, I'd like to translate de code below, write in octave, to R. I'm learning to operate R a few time ago, and an example of translation will be useful for me. This code is my lectures in an undergraduate course of statistical computing. echo off; k=0; while (k<>1) n = input('a prime: '); D = 2; r = n - D * floor((n/D)); while((D <= sqrt(n) & (r <>

I cannot seem to get this to work? I have weighted data points that I want to fit an sd-ellipse to, but the ellipse is not right? I have attached a .tiff of what I get. I'm wondering if it's not looking at my actual data, but taking the data from the example? I ask this because I don't know where "Title" comes from in the graph? Also, I want to put calcentre=FALSE, but if I

Dear helpers, I was wondering if there are some bivariate distribution simulation functions in any R packages. Specifically, I want to simulate bivariate log logistic, bivariate Weibull, or other common bivariate life time functions, and I can specify the correlations. Any comments about this will be appreciated. Thanks, Zhu Wang

Respected R Users, I looking for help with generating theoretical confidence regions for any of non-symmetric bivariate statistical distributions (bivariate Chi-squared distribution<Wishart distribution>, bivariate F-distribution, or any of the others). I want to to used it as a benchmark to compare a few strategies constructing confidence regions for non-symmetric bivariate data. There is
