similar to: R-beta: image axes

Questions on image: 1) How can I put labels on the x and y axes? 2) How to tell it to use e.g. 32 grey levels (not some colour map)? 3) How to know what the legend is (i.e. each grey level = what z value)? Thanks very much for any help. BTW I was wondering if persp was on the To Do list. That would be great! Bill Simpson

Over the years there have been inquiries to these lists as to how to produce plots with the direction(s) of axes reversed. In response to some of these inquiries, I have provided a function call ``rplot'' which automated the procedure for such axis reversal. Recently Herberto Ghezzo of McGill University pointed out to me that there was a bug in my code. I have now fixed this bug (and a

I include the argument pty="s" to image, but still when I make an image by the method > postscript("rstuff/test.ps") > tauseq<-seq(0,1,.5) > cif2d.image(x,,y,tauseq) > dev.off() the image plot created is NOT square. I thought pty="s" would make it square. Generally it would be nice if the image saved to disk were like the one we see while in R

Is it possible to create plot bty=o with different scale of left- and right x-axis? In my documents, by typesetting, bty=u looks disruptively. At 2nd: how to frame the whole box (including title and axes labels) and resize to landscape-oriented rectangle? Tomas Bayer

Hello there, Is there a functionality or command that generates axes in the shape of a capital Greek letter gamma (upside down L) ? I use these for making sediment profiles. I have read through help-lists, tried different things and asked several people but never got a satisfactory result. I've tried the following: xx <- c(2,4,6,5.8,5,4,3,1.5,0, 0, 0, 0) yy <- (0:-11) plot(NULL,

I know how to first set postscript output, then execute plot or image command to create a postscript file of a plot or image. I was wondering if it is possible to first create the plot or image on screen so it can be viewed, THEN save it to file? Without doing plot() or image() again? (I ask because I have a complicated image computation that takes about 1-2 hrs to complete. I would like to

Dear list, I'm writing a long document (thesis) and as much as I would like to use only ggplot2 for the graphics, some features are still a bit undocumented so I often end up choosing either ggplot2, lattice, or base plots (which i know better) depending on the particular graph to produce. With the default settings, this does not make for a consistent look I would like to see

I have a question on the use of return(). (Nothing on it in the docs I have) The test code below gives the error: Error: Object "x" not found when I do: thingy2(). How should it be fixed? Thanks very much for any help! (My original solution to this sort of problem was to use global variables x<<-... y<<-...) Bill Simpson ----------------------------- thingy<-function(k)

Hi I believe this is a clipping bug in the 'graphics' package. A simpler version of the problem is this ... plot(1:10) mtext("margin-label", side=2, at=9, las=1, line=1, adj=0) par(mfg=c(1,1)) ## Only the text within the plot region is drawn mtext("margin-label", side=2, at=9, las=1, line=1, adj=0, col="red") I have committed a fix to the development

Hi everyone, I'm trying to plot density curves on the axes of a plot, in a similar way to the 'rug' function. I have had a look at a few approaches and libraries, including: * layout http://addictedtor.free.fr/graphiques/RGraphGallery.php? graph=78 * fancygraph http://addictedtor.free.fr/graphiques/RGraphGallery.php? graph=81 * ggplot - gave up since it needs R 2.3.0 and

Thanks... I agree that the problem was explained in the documentation but I can't find a way to have axis() working even manipulating par("plt") or with graphics.reset = TRUE: - adding graphics.reset=TRUE does not allow axis() to be shown; - I see that par()$plt is involved but it is the not sufficient to explain why axis() works because if it is changed by hand, axes are not

I would like to have arrow heads at the end of my axes, since I am plotting variable where the absolute amount is irrelevant, there is not supposed to be numbers on the axes. An imperfect example: plot(rnorm(10),bty='l',xaxt='n',yaxt='n',ylab='',xlab='',type='l') abline(h=0) Like this but without, the xaxis and with arrrowheads More like this in

I don't rcall seeing this one reported before: plot(...,axes=F) removes not only the axes, but also the plot boundary. The 'bty' parameter loses its effect completely. getting it back seems to require fiddling with par("usr") and rect() or lines() (Linux, Alpha-3) -- O__ ---- Peter Dalgaard Blegdamsvej 3 c/ /'_ --- Dept. of Biostatistics 2200

Hi guys, I use R 2.6.2 and Windows XP. I’ve got the following question: I wrote a lot of text into the margin of a plot. When I use the “jpeg”-function, only a little part of the margin text is displayed in the final jpeg? Any ideas to change it? Source-Code: datenbankdaten<-data.frame(LETTERS[1:20],

Colleagues On occasion, I want to control either tick marks or labels in axes different from the defaults created with "axes=T" in the plot command. If I invoke "axes=F" and axis(n), I can do so. However, the axes produced by axis() differ slightly from those produced within plot. I have "bty" in par set to "l" (i.e., left and bottom axes

Here is a programming question. The code I am using is quite slow and I was wondering if there is a way to get rid of the for loop. I am dealing with "interaction" in 2x2 table, and am using Edwards's G_I (Likelihood, p. 194). I label the cells in the table as follows stim response "y" "n" total -------------------------------- y hit miss nsignal

Hello, I am creating plots of hourly precipitation and accumulated precipitation (on different axis, see attached image). I was wondering how can I have the plot frame (black border) start at zero, it looks like it is plotted less than zero? The code I use to create the png files is below: CairoPNG(PNG_file,width=1000, height=600, pointsize=14, bg="white") opar <-

Dear r-helpers, In my previous message there were comments in the code that may have made cutting and pasting awkward. Here it is w/o them. I have two questions: (1) The following produces a pdf with artifacts. How do I prevent them? require(grDevices) imSize <- 200 lambda <- 10 theta <- 15 sigma <- 40 x <- 1:imSize x0 <- x / imSize -.5 freq = imSize/lambda xf = x0 * freq *

Thanks for the proposition.
