similar to: R-alpha: plot(1); axis(1, at=10) >>> Seg.fault -- and a patch

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];

The following commands crash: > plot(1:4,axes=F,log="x") > axis(1,c(1,2,3,4)) zsh: segmentation fault R Lines 35-37 of axis(): 35: else { 36: ind <- (usr[1] <= at & at <= usr[2]) 37: } should be replaced by else { if (log) ind <- (10^usr[1] <= at & at <= 10^usr[2])

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?

There is a difference between R and S (or S-Plus, I'm not sure about that) concerning the generation of random numbers. If an error occurs during the execution of a function, the seed is restored to its old value in S-Plus, but not in R. This feature of S-Plus has just turned out to be very useful for me because I got an error message during a small simulation for a certain choice of

There is still issues with the reversed y-log scale plot: # Test case A: works as expected plot(10:100,log="y",ylim=c(100,11)) grid() par("yaxp") # Test case B: grid does not have horizontal lines; par("yaxp") is different plot(1:100,log="y",ylim=c(100,10)) grid() par("yaxp") In the second test case, axTicks for the horizontal lines (in

[I have abbreviated the subject as jitterbug has been having probems with long subjects.] The issue here is that one cannot mix log/non-log axes in the calls to screen(), as the appropriate par() parameter is read-only, but the meaning of yaxp depends on it. But beyond that you can't set x/yaxp for log axes. You should be able to do this: you can in the S original. A simpler version: plot

Not many of you will use grid() widely, probably. Also, two months ago, Paul Murrell said on R-help (topic "grid command") PM>> i think the abline() solution is the best for doing what grid() won't. PM>> like you say, grid() is just a simple front-end to abline(). grid() *is* too simple to be of practical use. I propose the following which is of some practical

Hi all. pretty() is now generic in R-2.12 and there are new methods for Date and POSIXt classes. These methods could potentially be used inside axis.Date and axis.POSIXt (and Axis methods), although that has not been decided yet. The main advantage of the new method is that it is flexible, in the sense that users can specify the desired number of ticks on an axis. (e.g. one could easily draw,

Hi, I've been trying to use several plotting routings that make use of S's par("uin"), the number of user units per inch. For the moment I've substituted all of the occurences of this with par.uin _ function() (par("fin") / c( diff(par("xaxp")[1:2]),diff(par("yaxp")[1:2]))) This seems to work fine for my needs. -Greg

hello everybody! i have a samba (3.0.24) running on a gentoo (alpha) box. i connect to a share using cifs and when i then run df -h, i get the following ahuemer@xeon distfiles % df -h Filesystem Size Used Avail Use% Mounted on /dev/sda1 34G 31G 3.3G 91% / udev 759M 2.8M 756M 1% /dev shm 759M 20K 759M 1% /dev/shm

Is there a function that does the same as pretty but on a log-scale? Suppose you have x <- exp( runif( 100, 0, 6 ) ) (which will between 1 and 403), then I would like to have a result like: log.pretty( x ) [1] 1 5 10 50 100 500 Bendix C. ---------------------- Bendix Carstensen Senior Statistician Steno Diabetes Center Niels Steensens Vej 2 DK-2820 Gentofte Denmark tel: +45 44 43 87 38

Hello, I'm new to R, and I'm trying to set the number of tickmarks for a plot using xaxp, but R seems to ignore this setting completely. Maybe you've an idea what I'm doing wrong.

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()

I hope it's OK to post a bug report, and a possible patch, on this list. Introduction ======= The split.screen() docs suggest that users should not return to a screen after it has been drawn, and that curious errors may result from doing so. This is clear from the test file I put below. However, I have found that this test file will work properly, with a tiny change to the split.screen

Hi, I am new to R plot. I am trying to scale my y axis in log. When I do this I receive the following error Error in axis(side = side, at = at, labels = labels, ...) : CreateAtVector [log-axis()]: axp[0] = 0 < 0! In addition: Warning messages: 1: In plot.window(...) : nonfinite axis limits [GScale(-inf,1.31772,2, .); log=1] 2: In axis(side = side, at = at, labels = labels, ...) :

Hello, apologies if I'm overlooking the obvious... I would like to revert a logarithmic axis with R 2.1.0 on Linux, e.g. for using pressure as a vertical coordinate. Say we have x = seq(1,3, by = 0.01) y = exp(x) Plotting and reversing linear axis is fine plot(x,y) plot(x,y, ylim = c(30,1)) as is a usual log-plot: plot(x,y, log = "y", ylim = c(1,30)) However,

Dear list, Could somebody who is more experienced with the Tcl/Tk interface from R please help me clarify the issues I've put below with ### --> tags? Several things go wrong, and it's probably because of messy code, but I have a difficult time finding out what is the cause. Thanks very much, JeeBee. require(tcltk) || stop("Package tcltk is not available.") # Add path to
