I recently built R 1.6.2 on solaris 2.8 with gcc 3.2. Things seem to run OK, but using graphics causes R to core dump. (For instance, by using the plot() or hist() functions.) Sometimes I can see the graphics drawn before it actually core dumps. The core file shows a crash in Rf_gpptr. I'm quite new to R, so I don't know what info would be helpful for diagnosis. I'm including the gdb dump of the crash. Thanks for any help! B Jones ------------------------------------------- GNU gdb 5.3 Copyright 2002 Free Software Foundation, Inc.

Is there a way to adjust the font size for axis labels when using persp()? The parameter cex works for adjusting the global font size, but I can't seem to make cex.lab or cex.axis work for adjusting these values independently. Or, is there a preferred method for making surface plots in R? I'm using R version 1.8. Thanks, Manuel

Hi all, In R, it is not possible to set the font size of axis labels directly (AFAIK). Instead, scaling factors for the font chosen by the graphics device can be supplied. It appears that there is no constant font size for axis labels. My impression is that the axis label font size is scaled internally by R depending on the number of labels given for an axis. In addition to the R-internal

Hi, I would like to get from a plot the size of the symbols plotted. Imagine I have the following plot function : plot(1:2,1:2, pch=15, cex=4) I would like the get the values SIZE1 and SIZE2 so that if I plot the following rectangle : rect(1.5,1.5, 1.5+SIZE1, 1.5+SIZE2) then the size of this square is exactely the same as the one of the symbols that have been plotted. Thanks for any idea. --

hi using plot(..., las=1), i.e. horizontal axis labels, the labels on the y-axis jams if the heigth of the graphics windov becomes too low while both x-axis and y-axis kind of removes superflus lables with las=0 (default) is there a way to make plot behave alike with horizontal lables? regards s??ren

...er I cannot find out how to convert the into units I can pass into lines(). I thought par("cxy"), but it is too large, as is shown in the code below. Here the red tick marks are longer than the black ones created by axis. I have found the relevant function in plot.c: "GConvertYUnits(Rf_gpptr(dd)->tcl, LINES, NFC, dd);" but can't find the corresponding R function. Can anyone suggest how to find this out, or solve the problem in a different way? # Inward pointing ticks par("tcl"=1) drawticks <- function(at) { # Start of the ticks base<-par("usr"...

Hi, I don't think this is a bug, but I thought I'd mention it in case others think it is not correct... I guess it is probably just a rounding error. If I use symbols() to draw some circles, any circle with radius of zero gets drawn as a small circle. As an example: postscript(file="test.ps") symbols(1:9, rep(2,9), circles=seq(from=0.05, to=0.0, length=9),

--==_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
