Hello, I use package "tcltk" to do some GUI programming, and want to find a function which can do the operation "click a button", just like using a mouse to click. If tkevent.generate can do that? I tried it as below, but failed. Please give me a hint! tt <- tktoplevel() tkwm.title(tt,"Simple Dialog") onOK <- function(){print("OK")} onCancel <-

Hello, I wish to plot some figures in a window in turn, but the size of these figures is different, so how can I change the size of the window by resetting the parameters before each plotting? Thank you, Shengzhe

Hello, In the Unix environment, I open a window by x11(). May I specify the position of this window by specifying the position of the top left of the window as in Windows environment? Or some other parameters can be used to do that? Thank you, Shengzhe

Hello, When I open a new device by "windows()", how to hide the 3 buttons on the top-right corner of this window, since I want to make these buttons not work, and the window can be closed only by "dev.off()" or "graphics.off()". Thank you, Shengzhe

Hello, I have a data set with 15 variables (first one is the response) and 1200 observations. Now I use pls package to do the plsr as below. trainSet = as.data.frame(scale(trainSet, center = T, scale = T)) trainSet.plsr = mvr(formula, ncomp = 14, data = trainSet, method = "kernelpls", model = TRUE, x = TRUE, y = TRUE) from the model, I wish to know the

Hello there, I have two data sets with 14 variables each, and wish to do the test for equality of their covariance matrices and mean vectors. Normally these tests should be done by chi square test (box provided) and Hotelling's T square test respectively. Which R functions could do this kind of test? I just find some functions could do for one dimension, but no for multidimension. Some one

Hello, I have a data set with 15 variables, and use "pairs" to plot the scatterplot of this data set. Then I want to plot some circles on the small pictures with high correlation(e.g. > 0.9). First, I use "cor" to obtain the corresponding correlation matrix (x) for this scatterplot. Second, use "seq(along = x)[x > 0.9]" to find the positions of the small

I've just installed Wine. Every Wine dialog box/window, on mouseOver, jumps the mouse cursor left and up, but sends mouse clicks to where the mouse would/should be. In other words, when I roll the mouse over any Wine box, the arrow symbol immediately moves left and up, then subsequently moves in relation to how I move the mouse, until the original mouse location exits the dialog box, when the

locator(n=1) returns the coordinates of the position of the mouse. But you have to click the left button of the mouse. How can I determine the mouse position without any click? Is it possible to extend locator in a way that locator(n=0) outputs the coordinates at once, without any click event? TclTk allows us to define very nice animations and demonstrations, see for example: demo(tkdensity).

How can I use R to record the time of a mouse click? -- Seth Roberts Associate Professor Psychology Department University of California Berkeley [[alternative HTML version deleted]]

Still googling, no joy so far (though I'm not giving up yet). Can anyone point me to a resource that may help me figure out how to make the side-clicks of the scroll wheel on a logitech mouse do something useful? thanks! -- ---- Fred Smith -- fredex at fcshome.stoneham.ma.us ----------------------------- "And he will be called Wonderful Counselor, Mighty God, Everlasting Father,

After some poking into psm.c code I've got some results. First, for the archives, debug.psm.loglevel tunable is much more useful than a verbose boot for debugging PS/2 mouse issues. A good value is 2. Second, I fiddled with various probe methods to force them to "recognize" my mouse (by loosening their checks) and found out that the mouse works perfectly if it is treated as

Hi all, I have difficulty understanding WxRuby / WxWidgets event handling, hoping someone here can lend us some light. Im writing a simple gui app where I need to receive mouse click events from the shapes drawn on a canvas (a simple object inheriting from ScrolledWindow, as seen in many examples). Shapes arent buttons so I think I''ll need to be checking the coordinates to be able to

I'm using the MATE desktop (via 'yum groupinstall "MATE Desktop"') on CentOS 7. I'm finding the mouse to be rather flakey in the sense that: - in MATE Terminal, clicking on text and dragging the mouse (in order to highlight the text and copy it to the X cut & paste buffer) will sometimes drop the highlight (thus not copying anything), or stop and

What I want to do is: 1, creat a text box, insert text into that box. 2, select chunk of of the text by mouse, and link it to a lable. so I would like a way to get that chunk of text. Can I do such job with tcltk? Any relavant tutorial materials?

I recently got an EEEbox. This is an Atom based nettop. It came with a wireless keyboard/mouse which talk to a 2.4Ghz USB adapter (a Chicony device as it turns out). Now if I plug this adapter into a Centos 4.8 machine both the keyboard and mouse are detected... but mouse clicks aren't. I can move the mouse, the scroll wheel works, but buttons 1/2/3 aren't detected. Neither in X nor

Hi All, Over the years, I have written a number of custom time series graphing modules (in ANSI C). I want to make these graphs available in R. After considerable thought (as well as feedback fom this NG - thanks go to Don MacQueen and Paul Murrell), I have decided to re-write (atleast some of the routines in R). Basically, this is what my R function needs to do: 1. create a parent

First of all, all other games and software work perfectly in Wine. I installed Sierra's The incredible machine - even more contraptions, which installed fine. No complaints or anything. The game started up nicely and everything seems to work fine, but my mouse buttons do not work at all. It does no register any clicks of my mouse, but I can move around the menus by moving the mouse over a

While playing around with panther I discovered (with surprise) that tcltk seems to work (even if not smoothly) with RAqua without first calling tkStartGUI. I switched back to 10.2.6 and it works as well. I think this is due to the "last minute" fix in RAqua now using idle timers because of too much cpu usage. Some "mouse" trick is needed though. If you want to test it you

Dear anybody dealing with TCLTK on R I'm trying, without any success, to get a simple TCLTK window to remain floating on top of the RGui and RConsol windows when the later have focus. I cannot find reference in the TCKTK documentation and fear that I'm missing something quite fundamental. My objective is to make a simple button populated menu to invoke R functions. I wish the TCLTK menu
