Hi, How to mark points on x axis of a graph keeping x axis as constant and changing y from y1 to y2 respectively. I want to highlight the area from y1 to y2. Any suggestions Thank you Jeet [[alternative HTML version deleted]]

The tkrplot package is not working in version 2.13.0 for windows. I contacted the maintainer who unfortunately does not have easy access to a windows computer and says that it is working on the other platforms. I traced the problem down to the line in the .First.lib function: .Tcl(paste("load", file, "Rplot")) With file being "C:/Program

Oh sorry. An example say lots more than words. The data below, when submitted to twoord.plot return the mentioned error.

I have some data fit to a smooth.spline object as follows: (x=vector of data for the predictor variable, y=vector of data for the response variable) fit <- smooth.spline(x,y) Now, given a spline fit point y_new, I want to be able to find out what value of x_new yielded this fit value. How to do so? (This problem is the inverse of the predict.smooth.spline function, which takes x_new as input

Hi all, I have two questions. Can some one give some help? The first question is regarding the pair of operators "&" and "&&". What is the difference between the two? The second question is regarding "<-" and "=". Usually we use "<-" as the assignment operator. I saw some people use "=". Is there any

hello, i did several binomial tests and noticed for one sparse dataset that binom.test(1,1,0.5) gives a p-value of 1 for the null, what i can't quite grasp. that would say that the a prob of 1/2 has p-value of 0 ?? - i must be wrong but can't figure out the right interpretation.. best, kay ----- ------------------------ Kay Cichini Postgraduate student Institute of Botany Univ. of

Hello, Anyone who knows a fast and accurate algorithm for generating draws from an underdispersed Poisson distribution. Or even better, if there is a package containing such an implementation. Thanks Rene

Dear Friends, Here is an algorithm for finding concave hulls: http://get.dsi.uminho.pt/local/ Has anyone implemented such an algorithm in R? RSiteSearch('concave hull') didn't reveal one (I think). _____________________________ Professor Michael Kubovy University of Virginia Department of Psychology Postal Address: P.O.Box 400400, Charlottesville, VA 22904-4400 Express Parcels

Hi all, I want to plot trough pairs() plot a matrix with 4 columns. I want to make a trhee plot in a graph. Plotting pairs colum 2,3,4 on y axis and 1 on X axis. You mean (a plot with three graphs) ommitting the first pair with itself. And only the pairs with colum 1 with the other not all pairs. I. e. this matrix 4177 289390 8740 17220 3907 301510 8530 17550 3975 316970 8640 17650 3651 364220

Hi, I have finally installed TeachingDemos trough zip file and installed on lbrary. One new question: I want to draw a line (like abline) on diagonal or the result of running a ols. How can I do it. On the other hand, I want to mark the length on each sub plot y axis. It is possible? My function is sca<-function(){ z2<-read.table("Ase.txt",header=T)

Hi, I would like to create a list recursively and eliminate my for loop : a<-c() a[1] <- 1; # initial value for(i in 2:N) { a[i]<-a[i-1]*b - c[i-1] # b is a value, c is another vector } Is it possible ?

Hello all, has someone please a few hints about how to 1.st: draw an image (preferrably a jpg) and then 2nd: plot() on that image I am using a mac - and after searching and trying different ways (I have installed EBImage) I now would like to ask for help... Thanks! Johann

Dear Duncan and other R users, The department in which I work will soon make some decisions to improve our reporting. Since I hope that our solution will support R and Sweave-like functionality (otherwise it wouldn't be an improvement....), I hope it's ok to repeat my question back from June if there are any news on an odfWeave-like package for weaving Microsoft Word documents? (in the

[I am really sorry if it is double posted, I doubt me previous post could not reach forum due to some problem with net] Suppose I have a matrix : a = matrix(1:9, 3) >From this matrix, I construct 9 additional matrices : i = 1:9 bi = a * i Now combining all those 9 new matrices, I construct a final metrix as : c = b1 b4 b7 b2 b5 b8 b3 b6 b8 I want to automate this procedure for any

Hello all!!! 1) I am wondering is there a way to generate random numbers in R for Bivariate Uniform distribution? 2) Does R have  built-in function for generating random numbers for any given bivariate distribution. Any help would be greatly appreciated !! Good day! Haneef Anver [[alternative HTML version deleted]]

Hi all, I'm trying to draw a contour plot with rounded (smoothed) contour lines instead of sharp angles; when the grid consists of only a few points in x- and y- axis, the resulting contour is in facts rather ugly since very sharp angles may appear. I did not find any way to do it, by using either "contour" or "contourplot" (from the lattice package), I wonder if there

Hi, this is probably a very trivial question but I can't figure out the right terms to find the solution in the list archive. I have a matrix or a data.frame or the like: > m <- matrix(ncol=3,seq(1,9)) > m [,1] [,2] [,3] [1,] 1 4 7 [2,] 2 5 8 [3,] 3 6 9 and now I wonder if one can provide somehow two vectors, one containing row numbers, the other
