Still playing with Lattice... I want to use panel.text(x, y etc) but with x and y in plot coordinates (0,1), not user coordinates. I think if I had this problem with traditional graphics, I could use grconvertX to make the change. I did come across convertX {grid} but this doesn't seem to be what I need. Is there a function like grconvertX in Lattice, or is there a flag or some other method of making panel.text use plot coordinates? Thanks, Bryan

..., at=c(1,2,3,4), labels=c(1,2,3,4), tick=T, las=1) par(new=T) plot(x=stm$dal, y=stm$model, ann=F, axes=F, type="l", col="black", lwd=2) Ideas involving the use of par(usr=c(,,,)) haven't solved the issue, and attempting to convert the x-axis coordinates using the function grconvertX() hasn't worked either. Using the axis function as shown here hasn't helped either. The function above called tad.image() was written by someone else, but it calls the image() function to make the plot shown. http://www.nabble.com/file/p21362251/test.plot.jpeg test.plot.jpeg -- V...

Dear all, How can I label/unlabel points on scatterplot with mouse pointer. As the mouse approches near to point, it should label the closest point, then unlabel when it moves away. How can I do in R? I be very thankful. Thanks and Regards, Hitesh Singla -- This message has been scanned for viruses and dangerous content by MailScanner, and is believed to be clean.

Hi, Is there a way to set the scale of a plot (i.e. number of axis units per centimeter) when you output it to postscript? If not, how am I supposed to plot graphs with different axis limits to the same scale? They just get resized to fit the paper so that graphs which show a smaller number of axis units end up with a larger scale. Cheers, Ben -- Dr. Ben Kenward Department of Psychology,

hi all - i'm having some difficulty figuring out how to convert between "user units" (which i can't find a definition for in the plotrix package) and either (a) device units (e.g. inches with PDFs) or (b) user coordinates along any particular axis. as an example, suppose i set up a PDF device with inches, the device has both outer and inner magins, and the plot region has

Dear Users, I already posted this question: it either went unnoticed, or it is to basic (if this is so, please sent me a hint). I would like to know if there is a way to add a common legend to an arrangement of plots. In the example below, I get four plots in my device. each one has a density for 1995 and one for 2006. I have found that using legend or smartlegend I can add a legend to each plot,

hi, I need to draw a line joining graphs,but abline stops within a graph.What do i do to cover portions between two graphs -- Rajesh.J [[alternative HTML version deleted]]

I generated maps with the function symbols (graphics). These are basic maps generated with : symbols(x,y,circles=myvariable) where x et y are spatial coordinates corresponding to replicates of "myvariable". I would associate legend to this kind of maps, is it possible? Regards, Marion. -- Marion Jacquot Laboratoire de Chrono-environnement UMR UFC/CNRS 6249 USC INRA Universit? de

hi Rusers I am trying to use symbos in gtools package symbols(data1,data3,circle=data1/data3,inches=0.1,bg="lightgreen") Now I want to give a lengend to tell the reader the meaning or magnitude of these circle. How can I add these information in symbols plot just like legend in plot ? thank you . -- TANG Jie Email: totangjie@gmail.com Tel: 0086-2154896104 Shanghai Typhoon

Hi R users, The margin parameter mar is measured in unit of lines, the size of which is automatically adjusted during plotting. I am wondering how can get the size of a line and how can I control the margin size by controlling the line size? (I know I can use mai to control the absolute size of margin, but in some situations that parameter does not exist. For example, heatmap() only accept mar as

I would like to plot some text in a existing plot graph. Is there a very simple way to do that. It does not need to be pretty at all (just maybe a way to center it or define a position within the plot). ( ? ) Ralf

Hello, I would like to place some text that should appear in the same position of the graphic device, preferably outside the plotting area, regardless the x and y axes limits. How can I do this?

I am creating a CDF plot function more user-friendly than any default r function. Depending upon the bimodality of the data (it is often bimodal), or any other strange data trends, the points can end up gathering in just about any corner of the plot. So, when I add a legend, whether I choose to add it in the bottom right, top left, or wherever, it will sometimes end up putting the legend right

Dear R users, I have been plotting several graphics in only one page. I intend to plot only one legend in each page. Since the graphics are inside a loop I have to do it automatically. The main problem is that inside the loop I work with differente types of variables, I mean , the range is different for each one. I have already tried : par(xpd=TRUE) pos<-par("usr")

Hi, I have a 2D chart that is divided into four quadrants, I, II, III, IV: plot(1:10,ylim=c(0,10),xlim=c(0,10),type="n") abline(v=5,h=5) text(x=c(7.5,7.5,2.5,2.5),y=c(2.5,7.5,7.5,2.5),labels=c("I","II","III","IV")) I would like to fill each quadrant with a background color unique to the quadrant. Does anyone know how to do this in R? Thanks, --

Hi: I would like to find out the panel of a xyplot matrix where a mouse clicked. I know this functionality is already bundled in trellis.focus but I can't use it because I am coding a stand alone application in Java using with GDCanvas as a graphics device. I tried calling trellis.focus from Java with: re.eval("t = trellis.focus()")); However it did not work for an embedded

Hi, is there a way to place text at the upper left corner (or another corner) of the plot? I want to place it really at the upper left corner of the whole plot (the file I get), not at the upper left corner of the plot-region. I tried text() and mtext(), and corner.label() of the plotrix package but it didn't work out. thanks!

Hi, Does anyone know if there is a way to 'reset the plot number' on a traditional graphics device? For instance, I want to have two plots on stacked top of each other (mfrow=c(2,1)) but with underlying grid lines spanning both figures vertically. I can put the grid lines on top if I add them last: par(mfrow=c(2,1)) plot.new() plot.window(c(0,1),c(0,1)) for( i in 1:2) axis(i)

Hi, I need to draw a line segment between two points on different plots in the same multigraph.I've tried looking at the zoominplot function in plotrix but havent understood much.any help is appreciated ~Aks [[alternative HTML version deleted]]
