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 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

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

I have re-labeled tick marks on the x axis. The problem is that by using axes=FALSE, the axes disappears and when they are called back using axis(side=1)..etc. the axis on sides 1 and 2 do not meet at the bottom left corner of the graph. I would also like to have the 3rd and 4th axes in there as well, all meeting in their respective corners. par(mfrow=c(1,2)) gut<-c("Full",

R Help, I posted a question on StackOverflow yesterday regarding an issue I've been having with the RgoogleMaps packages' displaying of axes. ?Here is the text of that submission: http://stackoverflow.com/questions/6258408/rgooglemaps-axes "I can't find any documentation of the following problem I'm having with the axis labels in RGoogleMaps: library(RgoogleMaps) datas

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

Hi, Splus allows pasting a graphics object into the plotting window, which makes it possible to do what you describe below. Now I use R which doesn't seem to allow pasting the picture into the graphics window, so I copy the graph onto a transparency sheet, and stick it onto my screen using tape. The coordinates need to be converted to make sense (as you describe). My methodology with the

I'm using plot to make a simple plot but I want to control where the tick marks go on bot axes. The graphical parameters xaxp and yaxp seem to be ignored by the plot function so I tried setting them using op <- par(no.readonly=T) par(xaxp=c(-2.4,-2.2,5), yaxp=c(-2500,10000,6)) plot(...) par(op) but they are still ignored. Next I tried to use the axis function as follows op <-

[Sorry, resending with a proper subject line!] Hi Guru's... I have a set of points that may lie along any of the x, y and z axes in a Cartesian coordinate system. I am hoping that a function exists which will determine if any two selected points are on different axes, i.e, if the one of the points is on x and the other on y or z, not elsewhere on the x axis. Put another way, I need

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

There's a non-compatibility between R and S-plus with the default argument of the locator() function. R has locator(n=1) S-plus has locator(n=500, type="n", noclick=F) S's default is ``better'' I think, insofar as it means in 99% of the cases ``user clicks <left> as many times as wanted and then clicks <right> to end'' Ross Ihaka and his grad

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).

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
