similar to: R-alpha: R 0.50.a1: small patches for graphics and image demo

Greetings, Mr Bivand and all the other authors, I'm glad to say that there are some encouraging advances in my debugging progress. Thanks to Mr Brivand, I could check the packages installed on my oparation system. I have found that I have only one of the two font files installed-'xorg-x11-75dpi-fonts' installed and left the other one. So I have it ('xorg-x11-100dpi-fonts')

The line contour(volcano, x, y, l, col = "yellow", lty = "solid", add = TRUE) needs to be changed to contour(x, y, volcano, col = "yellow", lty = "solid", add = TRUE) A patch is appended below. -k *** demos/graphics/graphics.orig Thu Apr 17 11:02:39 1997 --- demos/graphics/graphics Thu Apr 17 11:03:08 1997 *************** plot(numeric(0), numeric(0),

Dear All, I was looking for the color index in?image function,?such as from topo.colors(n) and etc. but still never found it. For instance, from the help menu. ########################################### # Volcano data visualized as matrix. Need to transpose and flip # matrix horizontally. image(t(volcano)[ncol(volcano):1,]) # A prettier display of the volcano x <- 10*(1:nrow(volcano)) y

Hey Guys, I'm trying to install R on an SGI IRIX 5.3 machine. I'm having trouble getting R to use POSIX regular expressions. Here is the error message I get when I run help: > help() Error in gsub(pattern, replacement, x, ignore.case, extended) : POSIX regular expressions not available I looked through the R-help archives and I found a few tips concerning the problem. I tried them

Do you know what steps I need to take to add a scale to a plot? I'm pulling my example out of "An Introduction to R: Software for StatisticalModelling & Computing" (see the R code around Figure 76). I would like to add a scale to the image produced by the following code.? I would like to the scale to list the distance?and units:? data(volcano) x <- 10*(1:nrow(volcano)) y

Hello, lately I've been playing with the idea of doing in-place updates of systems using either rsync or xdelta. However, both rsync and xdelta seem to be dead set on writing a new file first, and then atomically exchanging it with the old file. Now, as I want to apply a binary delta to a full filesystem, bigger than the available temporary space, this really makes rsync and xdelta

Hi I have a system that I'm trying to run `yum update` on. It fails with the following error: Running rpm_check_debug Running Transaction Test Finished Transaction Test Transaction Check Error: file /usr/share/man/man1/xdelta.1.gz from install of xdelta-1.1.4-1.el5.rf conflicts with file from package xdelta-1.1.3-20 file /usr/share/emacs/site-lisp/psvn.el from install of

Has xdelta (in ports under misc/xdelta) ever been considered as a means of delivering binary patches for security updates? It seems to be a pretty neat. -- Regards, Michael Nottebrock -------------- next part -------------- A non-text attachment was scrubbed...

A set of patches for R-0.50-a1 is now available as ftp://stat.auckland.ac.nz/pub/R/R-0.50-a1.patch1.gz The patches mainly fix problems reported since R-0.50-a1 but some older problems are also fixed. Here is the list of changes. Ross o Many subsetting and mutation problems with the new "expression" type have now been fixed. o When ask=T is set in par() the user is instructed

can you recommend a good manual for R that starts with a data set and gives demonstrations on what can be done using R? I downloadedR Langauage definition and An introduction to R but haven't found them overly useful. I'd really like to be able to follow some tutorials using a dataset or many datasets. The datasets I have available on R are Data sets in package 'datasets':

Hi R-help community, Can anyone tell me why, while using : x <- seq(as.Date("2001-01-01"),as.Date("2001-01-01") + nrow(volcano)-1,1) y <- seq(1, ncol(volcano),1) when I plot the volcano matrix with that command : filled.contour(x,y,volcano) the graph has a Date format on X-axis, ok ... ... but when adding a contour plot to the filled contour, using this

Karline, Thank you for your help. I discovered that in addition to including clim, I needed to omit breaks. This code uses one of your other examples as a starting point and works as intended: persp3D(z = volcano, zlim = c(-60, 200), phi = 20, colkey = list(length = 0.2, width = 0.4, shift = 0.15, cex.axis = 0.8, cex.clab = 0.85), lighting = TRUE, lphi = 90, clab =

Hello, I'm currently using a boxplot to visualize data for three different models. As I have three models, I'm plotting three parallel boxplots for each factor. This works fine - what I need now is a line connecting the medians of each boxplot of each model. I want to do this in order to visualize the trend that one of the models exhibit. Basically, I want to plot a curve for each model

Hi list, I wonder if anyone has had this experience with squishplot() in the TeachingDemos package. Taking the example from the ?image help page, library(TeachingDemos) x <- 10*(1:nrow(volcano)) y <- 10*(1:ncol(volcano)) layout(matrix(c(1,2,3,4),ncol=2,byrow=TRUE),height=c(2,1)) ## 1st plot op <- squishplot(range(x),range(y),1) image(x, y, volcano, col = terrain.colors(100)) par(op)

Hello, I would like to plot specific SNPs with their exact locations on a chromosome. Based on my genotyping results I would like to separate these SNPs in three different categories: 1, 2 and 3 and use different colours to represent these categories. The script below generates the sample data. I can plot these with the image function using the following: val <- 1:3 samp <- sample(val,

Is there a way to make a shading interpolation on an image plot? Something similar to matlab 'shading interp', I think it is called Gouraud shading. What I want is to make a image plot look nicer. with image() it looks very facetted, and I would like to make it look smoother. I've tried with interp.surface() in fields package but it (obviously) makes nan values at the borders and

Hi All, I'm running CentOS 5.3 x86, and recently my yum update isn't running as it should. It pops up with sub conflict messages for i386 packages, which I don't need - even though yum is downloading them. Due to this sub conflict messages, I'm not able to update/install my x86 packages, as the installation stops at the error message. Anybody, any idea how to come over

Hello, I would like to suggest the following change to image.default in src\library\graphics\R\image.R: 98c98 < plot(NA, NA, xlim = xlim, ylim = ylim, type = "n", xaxs = xaxs, --- > plot(x[1], y[1], xlim = xlim, ylim = ylim, type = "n", xaxs = xaxs, This provides all the support of axis.POSIXt that plot.default gives, currently the default new plot in

Hi, I am doing composite plots with the package plot3D. One of my variables is qualitative and indexed to integers, and I would like the legend for it to have labels located at the integer values (midpoints), and not at the breaks between classes. In the example below, the Elev Classes legend has labels at the breaks and nothing at the midpoints. How can I show the class labels at 1:3, and not

Hi! Whenever I save a graphic in ps/eps format generated by filled.contour or image, an undesired grid is added to it (not visible on the X11 screen). For example: postscript("volcano.eps") filled.contour(volcano,col=gray(seq(0,1,,50)),levels=seq(min(volcano),max(volcano),,50)) dev.off() Any ideia how to eliminate this grid?
