--==_Exmh_1801894504P Content-Type: text/plain; charset=us-ascii Dear R folks, Initially I had a plotting routine using logarithmic y-axes that failed after repeated calls if I tried to restore the graphical parameters (which I wanted to do because I used `layout' within the routine. I tried to isolate the problem and found out that the following code with logarithmic axis is sufficient for

Here are another three problems with logarithmic scales: 1) segments() does not work with logarithmic scales. I suggest to change lines 962-973 in "plot.c": for (i = 0; i < n; i++) { if (FINITE(xt(x0[i%nx0])) && FINITE(yt(y0[i%ny0])) && FINITE(xt(x1[i%nx1])) && FINITE(yt(y1[i%ny1]))) { GP->col = INTEGER(col)[i % ncol];

Hi again, another problem: This (below) isn't working and as far as I can see it damn well should. What I'm trying to acomplish is to run several data sets through the same graphing procedure, but for the pH data use a log y axis. using this code all graphs are drawn with a linear axis. Surely I should be able to set the ylog option to T using another object (logaxis). for (n in

1) 'par' doesn't seem to be called from 'plot', as it is in S. I was able to get the plot to work with: par(mar=c(5,5,5,5)) plot(a,b) axis(4,labels=F,tck=0.1) mtext("blabla",side=4,line=3,cex=1.5) NOTE: I tried this on the x11() display, which seemed to reproduce the problem you described. 2) ?? I was unable to get either x or y logarithmic axes using

I use R on linux and I go through exceed from a windows machine. Depending on the amount of plots I do on a screen, sometimes the numbers on the vertical axis of the plots don't show up. I tried infinite of combinations of mar and cex but nothing helps. Yet, if instead of shooting the graphic upto the screen, I send it to a pdf file or a postscript file, the numbers on the vertical axis of

This problem has been mentioned by Arne Kovac <maak@stats.bris.ac.uk> on May 9-10. The patch is really a replacement of 'axis' in RHOME/src/library/base/funs/ It contains the fixes which where proposed Arne Kovac and fixes (all?) the errors he/she (?) reported on May 9. "axis" <- function (which, at, labels = TRUE, ...) { if (which%%2 == 1) { axp <-

Hi, are there any plans to add a colorbar legend to image()? Or such a possibility already implemented which I just haven't discovered yet. Anyway, I will be willing to spent some time on the implementation if there isn't anyone working on that already.

I'm working on my 'oce' package, trying split.screen() instead of par(mfrow). My code is too long to post, and I hope it's ok that I ask this question without doing so. My code seems to work fine when I source() it, but when I do "R CMD check" on my package, I get the error that I've put as the subject line, when it runs examples. If I comment out the plot()

Hi, I'm trying to construct a legend which has four lines of text and associated symbols. The first two symbols need to be normal lines which vary only in colour. The second two symbols should have filled boxes. How do I suppress the fill boxes in the first two lines? J.

Running R 1.2.3, Windows 98 I checked the archives, and I couldn't find anything pertaining to this: How do I control format (scientific notation versus decimal, e.g.) on tick labels?

I often use something like old.par <- par(set someting) on.exit(par(old.par)) but in R 1.7.0. I now get warnings: > old.par <- par() > par(old.par) Warning messages: 1: parameter "cin" can't be set in: par(args) 2: parameter "cra" can't be set in: par(args) 3: parameter "csi" can't be set in: par(args) 4:

Hello dear members of R-help and R-core mailing list, I am not sure if this request is a "ticket" that should be filled somewhere outside the mailing list. If so, I apologize for not doing and would like to know where I should have filled it. And to the subject matter: I would like to use a command like this: plot(c(1,8), 1:2, type="n") polygon(1:7, c(2,1,2,NA,2,1,2),

Hi, R friends. I had some difficulty with the following code: qqnorm(freq, log='y') qqline(freq) as the line drawn was seemingly random. The exact data I used appears below. After wandering a bit within the source code for "abline", I figured out I should rather write: qqnorm(freq, log='y') par(ylog=FALSE) qqline(log10(freq)) par(ylog=TRUE)

Hi there, I guess this must be a standard issue, but I'm starting to go crazy with it. I simply want a plot with the x axis being logarithmic, having labels 1, 10, 100..., and ten unlabelled ticks between each of them - just as they introduce logarithmic axis at school. I've played around a bit with log="x", xlog=T (where exactly is the difference here?), xaxp, and xaxt
