In Win95/NT you can use xgobi (program and R interface) as well, provided you will install an x-server on your machine (a free one is available from http://www.microimages.com/freestuf/mix/).

Dear all, do anybody know how to set ylim in barplot() correctly? When I write: > barplot(c(.1,.5,1.0)) the y-axis goes from 0.0 to 0.8. Wheny I type: > barplot(c(.1,.5,1.0,),ylim=range(0:1)) the y-axis goes from 0.0 to 0.8. Obviously I am doing something wrong. Are the ylim setting standards in barplot() other than in plot() or is this a bug? Thanks for any hints! Zdenek

Dear all, sorry for this perhaps stupid question, but it concerns my recent problem as well as the current thread on B-A plot. I would like to plot something like x+y vs. x-y or mean(x,y) vs difference (x,y), but my "variables" x,y are actually pairs of replicates (two observed values of a growth rate by 60 clones). So the order x,y does not matter and each x,y pair can be arranged

Dear all, first, I would like to thank R-core team for making so a great software available. Thank you all, really! Using R (1.0.0) on a Win98 platform, I need an x-server to run xgobi (through R xgobi interface). I've been using a MI/X server but trying to upgrade I noticed that MI/X is no longer available for free. Similarly, eXceed is available at evaluation version (for a limited time

Hi all, I am using rw0632b on Win95 machine. When printing plots (both, as saved *.gif, and copied through clipboard) I get pretty low resolution. Can be the graphics resolution paramatrized in some way? Many thanks!

Sorry to all bothering you with a trivial question: I am using R (rw0630 for Win32) and am simply unable to read-in the *.txt data. I've tried to copy the file (prum.txt) to different directories of rw0630 but get uniformly the answer "object "prum.txt" not found". Which is the default directory for read.table() ?? Thanks! Z.

Dear all, I would like to ask your advice about a suitable computer for the following usage. I (am starting to) work with moderately big data in R: - cca 2 - 20 million rows * 100 - 1000 columns (market basket data) - mainly clustering, classification trees, association analysis (e.g. libraries rpart, cba, proxy, party) Can you recommend a sufficient computer for this volume? I am routinely

Greetings, I have what I hope is a simple question. I would like to change my contour interval on the vis.gam( plot.type="contour") in the mgcv package. Is this a situation where I need to modify the function or is there a default value I can change? Thanks

Dear all, apologies for this (perhaps recurrent) question but I did not found a question when searching mailing lists. How to write a list of a simple kind, e.g.: abc <- list(one=(1:2), two=(1:5)) # to a file? I understand that write() & co. cannot work but when I try sink("aa.txt", append=T, split=T) abc sink() # the output is indeed "split by rows" in the

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

Hello, I created a 3d surface (persp) with some points overlaid on it, which is fine. Now I have a second set of z-values(x,y-values same as the first surface), which I would like to make visible on the same graph, however, not as a surface, but rather as coloured contour on the first surface, so that the resulting graph will consist of the original surface having the colour of the second

Dear All, I have been trying to to do this for a few days now. I can generate persp plot OK and can generate it in colour using the command persp(x,y,z,col=terrain.colors(20)) However, I was wondering if it is possible to shade the 3d surface like a contour plot. i.e. black for large z, white for small z, say Thanks in advance Colin

Dear WizaRds, I would like to create a 3d-plot with persp(). I sampled 17 points with xyz-coordinates (real-life example!), representing the peaks of the whole plane with "zero coordinates" x=3,y=3,z=3. My intention is to show which entries are above or below the "zero" level with persp() on a nicely created grid. I also tried scatterplot3d(), but, alas, I am unable

Hello list. I very often need 3d scatterplots, and use scatterplot3D quite a lot. I am trying to modify persp() to plot scatterplots, and make use of the theta and phi arguments that persp() offers. I am having some difficulty passing the correct arguments to persp(). Here is my function so far. Much of it is copied from the persp() manpage. points3d <- function(x,y,z,

Hello folks, i'm a R beginner and i want to put in a same plot both contour lines and persp plot. For example, fn<-function(x,y){sin(x)+2*y} #this looks like a corrugated tin roof x<-seq(from=1,to=100,by=1) #generates a list of x values to sample y<-seq(from=1,to=100,by=1) #generates a list of y values to sample z<-outer(x,y,FUN=fn) #applies the funct. across the combos of x

Suppose I have three numbers p1, p2, p3 with 0 <= p1,p2,p3 <= 1 and p1+p2+p3=1, and a function f=f(p1,p2,p3) = f(p1,p2,1-p1-p2). How to draw a contour plot of f() on the p1+p2+p3=1 plane, that is, an equilateral triangle? Functions triplot(), triangle.plot(), and ternaryplot() give only scatterplots, AFAICS -- Robin Hankin Uncertainty Analyst National Oceanography Centre,

I have this data set that both x & y are ordered vectors of length 600 & 700 respectively; z is a 600 by 700 matrix whose entry z[i,j] is either a missing value (indicated by 'NaN') or a real number between 0 and 1. The contour function contour(x,y,z) gives me a blank picture. I guess the reason is that most of z-entries are missing, only less than 1% are non missing.
