similar to: par help wrong: xlog & ylog (PR#497)

--==_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

Full_Name: Bill Simpson Version: 65.1 OS: linux Submission from: (NULL) (193.62.250.209) Try this code as separate lines entered interactively, then try doit() doit<-function() { x<-seq(1,10) y1<-x+rnorm(10,1,1.5) y2<-x+rnorm(10,1,1) t.test(x,y1,paired=TRUE) t.test(x,y2,paired=TRUE) } doit() apparently executes only the last of a series of t.test()s. Maybe this is no bug,

Full_Name: Bill Simpson Version: 0.64.1 OS: linux Submission from: (NULL) (193.62.250.209) Two problems with dev.print help. 1. Under Examples: dev.print(width=6, height=6, horizontal=F) ^ FALSE 2. dev.print help does not describe any of its parameters (e.g. height or width). Not described on the other dev.xxx pages either

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];

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

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.

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

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 just installed 99.0a, and I can't set mar and mgp: > par(mar(2,2,.1,.1)) Error in par(mar(2, 2, .1, .1)) : couldn't find function "mar" I had the same happen with mgp. Are these bugs or a problem in my installation (everything else seems OK)? Is R core going to kill mar and mgp? If so, how should I fix the huge margins and huge space between axis title and axis? Try this

I use AfterStep on Linux. I made an R.xpm file (attached) and put this icon in the "wharf". To invoke R I click on the R icon. I did not find an offical R.xpm, and so I am submitting this one for your collective consideration.... The idea behind the icon is that it looks like a scatterplot, which is "statistical". My main beefs with my R.xpm are that it doesn't have a

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?

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 <-
