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

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, I have a large plot that I would like to display in a graphics device with scroll bars. I therefore decided to use the windows function like so... mag<- length(tick) windows(height=mag/8, width=10, rescale="fixed") However, when I use the scroll bars the device (i guess) is re-drawing the plot. Is there any way in which I can get it to 'smooth scroll'? Kind regards,

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 ideas on how to get this to work? Thanks in advance!

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 People: I have an interactive menu via an Rcmdr extension package which asks for lower and upper limit to evaluate. Typically, I use: assign("a",as.numeric(tclvalue(lowlim)),envir=.GlobalEnv) and that's fine. However, if I try to use pi or Inf or -Inf, I get either coerced NAs or NaN. Does anyone have any suggestions, please? Thanks, Erin PS Happy Easter if you celebrate Easter. -- Erin Hodgess Associate Professor Department of Computer and Mathema...
