Dear R users graphing with plot(x) seams to work for a small length(x), when length(x) is too large it seams to clutter the display, a solution would be to display subsets of x at a time, yet a better way which I hope R supports is to place a sliding bar on the display window to control length(x) and thus the resolution, which will involve auto scaling the y axis as well as automatically

Hi thank you for talking the time to help me with this. I have a sequence of numbers in a file and an equal sequence of various character, say(a b c d) each occurs more than once. I need to plot the numbers so that numbers corresponding to a in the other sequence would have green dots, those corresponding to b a red dot, nothing on c and blue square for d. i.e 2 a show a green dot 4 b show a

Hello everybody, I am wondering if it is possible to create a gui to plot a time series that is very big, it's an EEG signal of 20mins. What I would like to do is plot the first 5mins, then have a button on the gui that plots the next 5mins when pushed. Is it possible? Thanks in advance ! Gael.

Dear R users I need to auto scale the left y axis in the code below, so that when I scroll left or right the left y-axis scale changes to accumulate the range of the displayed data with in the max hight of the y-axis. also how can I make the crosshair horizontal since it is only vertical in this code. this code with a kind help from "Gregory (Greg) L. Snow Ph.D." just

Dear R-help list members, I'm writing a package using tcltk. Thanks to Peter Dalgaard's excellent work on the tcltk package, almost everything has gone very smoothly. I'm stymied, however, by the following problem: I want to incorporate a bitmap image, stored as an xbm file, in a widget. To take a simple example, top <- tktoplevel() tkgrid(tklabel(top,

Hi, I am working under Windows and I am using R2.11 I want to use tkscale in my GUI. As the interval is quite big, I can't set the scale to a certain specific value. Therefore I want to add tkentry to allow the user to set tkscale to a certain value. Here is the code library(tcltk) tt<-tktoplevel() tkpack(m1<-tkscale(tt,from=306870.00, to=3026741, label="alpha",

Hello there, I'm struggling with the base graphics system on different operating systems. I would like to get an animation effect by re-plotting with the plot function. See the attached code example: move the slider quick from one side to the other. I experience different levels of success, depending on which OS I use. - Linux (Ubuntu >9.10, R 2.9.2-3): Each plot command gets

Hi again R People: This works fine: > library(tcltk) > a <- tclVar("4.5") > as.numeric(tclvalue(a)) [1] 4.5 > #But if you have: > b <- tclVar("pi") > as.numeric(tclvalue(b)) [1] NA Warning message: NAs introduced by coercion > Is anyone aware of a way around this, please? thanks, Erin -- Erin Hodgess Associate Professor Department of Computer

Hello, On Mac OS X, certain Aqua/Quartz UI functionality requires an application to be launched from within an app bundle, or (alternatively) requires a Carbon application with a resource fork. Playing with the wxWidgets distribution, I discovered that it is quite easy and transparent to make such a Carbon app from (I guess) any command line application. When applied to the R executable called

Hi everyone, I have a problem to assign a value with tcl/tk ths is the code ( it should be simple to understand) : library(tcltk) valA<-tclVar("0") valB<-tclVar("0") valC<-tclVar("0") id<-"A" out<-"1" out2<-"2" print(paste("tclvalue(val",id,")",sep="")) # ok

I can set up an entry widget (thanks to an old post by Barry Rowlingson) that gets a password and exits when the user clicks on the "OK" button. Anyone have any clever ideas for returning/ destroying the window when the user types a carriage return/ENTER in the text window? I've messed around a little with validate, validatecommand, but don't see any obvious way to do it ...

I maintain the package affylmGUI. It works when installed on many previous versions of R. I have today tested exactly the same code under R-2.15.3, R-3.0.2, R-3.1.0, R-3.1.1, R-3.1.2 and R-devel. I have also tested the versions of affylmGUI downloaded by biocLite for each version of R and the same result applies. I have no errors under 2.15.3, 3.0.2, 3.1.0 and 3.1.1. The following error

Dear all R gurus, I have following syntax: y = c(1:10) chippy <- function(x) { y[5] = x sin(cos(t(y)%*%y)*exp(-t(y)%*%y/2)) } curve(chippy, 1, 20, n=200) But I am getting error while executing : Error in xy.coords(x, y, xlabel, ylabel, log) : 'x' and 'y' lengths differ In addition: Warning message: number of items to

Hi All... In an attempt to read data from a file and feed it into a tcltk entry box, I've run into difficulties. The following hopefully describes my dilemma: tclvalue(x.var) <- 5 Works fine. tclvalue("x.var") <- 5 Does not work. [Error: Target of assignment expands to non-language object] tclvalue(eval(parse(text="x.var"))) <- 5 Also, does not work. Any
