similar to: locator(n=1) or (n=500) as S-plus ?

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).

Is there a way to turn of the (annoying) beep that occurs when one calls the locator() command and clicks the mouse. Try plot(0) locator(n=10) I am running Rterm on WindowsMe/Cygwin bash and I don't know if this is the case on other platforms. Thanks to everyone! Henrik Bengtsson h b @ m a t h s . l t h . s e

I am attempting to use locator(n=2) to select the corners of several (5 in this case) rectangles on an image displayed in a JavaGD window. The returned coords are used to draw labeled rectangles around the selected region. I have tried several things to get this to work including sys.Sleep to correct what appears to be a timing issue with this loop. The first-time print in the loop

Hi Folks, I'm contemplating using locator() to digitise external graphics. To set context, I would be using X11 display on Linux. To pre-empt the obvious comment: I've found on the R site the suggestion to use the 'pixmap' package. I've tried this, and it works; but it involves building a big R object (the internal pixmap representation), and this chokes my somewhat puny

I would like to explore dendrogam plots interactively. For example, click on a node and return information about all of the children of that node. Is there a high level wrapper for locator() or click() that will return the nearest dendrogram node on a plot? If not, is there a way to obtain the [x,y] coordinates of all the nodes on a plot?

I appeal to those entrusted with the keeping of the R flame, the S flame, and the S-Plus flame to relate a bit of history. How did S, S-Plus, and R get their names? Going from S to S-Plus appears clear, a commercial company purchased rights to S, developed a product that they wanted to indicate was related to S, but was more fully developed. This leaves me with only a rumor how S got its original

Hi, I want to use R for some data mining project , and was wondering if it has any intercative graphical features? For example, is it possible to plot a histogram and be able to select a specific point on it and have all the data about it? or select a specific area in a curve and have all the data about it? or possibilities to zoom out and in? Thank you for your help, Mama Benchaffai School of

Hi, Using the following R-Code the printing via print takes place after locator although print is placed before locator ### test = function() { plot(1:10) print("test") locator(1) } test ### Is there some way to force the printing before locator is being evaluated. I assume that there is some buffer that needs to be turned off? Where do I have to look. Locator and print help page

In several tries, I am finding the locator and identify functions on the cairo device on Windows, with R-2.13.0, do not seem to work correctly. Here is my experience with locator where I click the four corners of the device window. First, with the windows() device, the results are consistent with what I see on screen > windows() > plot(1,1) > locator() $x [1] 0.6075000 1.3981252

Hi, I'd like to plot vertical lines on my plot using the locator.But since locator returns two values I end up getting 2 vertical lines for every click.Is there some way only the x coordinate from locator can be returned? -- Rajesh.J ------------------------------------------------------------ "I skate to where the puck is going to be, not where it has been." - Wayne Gretzky

Hello, I'm trying to write a function using tcltk to interactively modify a plot and gather locator() data. I've read Peter's articles in Rnews, the help pages in tcltk, http://bioinf.wehi.edu.au/~wettenhall/RTclTkExamples/, plus a post in R-help sometime ago, but haven't found a solution. The idea goes something like this: require(tcltk) testplot <- function() { getcoords

Hi, haven't been here for a while, but everyone one was always so helpful I thought I would ask you another really basic question. I'm running R2.9.1 in Ubuntu8.04 on a netbook (maxed out on memory etc so I don't think that's a problem - wth it's a Dell Mini 9" with that lpia non-architecture you told me about). Anyway, some of the graphics functions/parameters are

Hi all A couple of questions for you on domain integration: Firstly, can someone please explain to me where/how a samba device's site info is cached? I see from a trace that when winbind starts it goes through the usual process that a windows device does (DNS query for non site-specific SRV, LDAP query/response with site name, DNS query for site-specific SRV). - How is the site info

In both the versions of 0.63.3 I have compiled locator() gives silly results for log axes eg > plot(1:10,log="x") > locator(1) #click on the point at (4,4) $x [1] 9694.383 $y [1] 4.034130 It appears that the x coordinate is 10^right number -- it's getting unlogged twice --please do not edit the information below-- Version: platform = sparc-sun-solaris2.6 arch = sparc

I was wondering if someone could help me! Here is what I don't understand! Why the text in the function isn't showing up before the locator action? ########### plot(1:10) toto<-function(){ cat("Why this text isn't showing up before the point selection !!!!!!!!") point<-locator(2) return(point) } toto() P.S.: I am using the most recent version of R for mac Thanks

Dear R People: I'm using the locator() function on a chart and I select two values. Is there a way already in place to connect the two values with a line segment, please? Just thought I'd check before I started coding.
