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 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

Previously I had managed to get R-0.99.0 to compile and pass the tests on a Debian Linux/Alpha 2.2 system by recompiling src/main/optim.c by hand omitting the -O2 flag. I just tried R-1.0.0 on a similarly configured machine, although not the same machine as before, and it compiled ok but failed the tests. This time it fails on bessel> x <- seq(0, 4, len = 501) bessel> plot(x, x, ylim

...g out these adjustments, the x-axis text is clearly shifted up (i.e. the bottom of the text is aligned at the specified margin line) while the y-axis text is shifted left (i.e. the bottom of the text is still aligned with the specified margin line). 2) This observation lead me to realize that do_axis and do_title in plot.c assume padj=0 most of the time (there are exceptions depending on par()$las). I'm no expert in the R code base, but the yLineBias adjustments appears like they might have been intended to restore symmetry -- but it only works for mex=1. Is there a reason why, inste...

I've been trying to figure out a parameter that will let you separately adjust the parameters for the axis line from the tick mark. In the following example, I would like to suppress the axis line, but keep the tick marks. Thanks, Andrew foo <- data.frame(x=1:3, y=4:6) plot(foo$x, foo$y, type="n", axes=F) points(foo$x, foo$y) axis(side=1, at=foo$x, lty=0) #would like to figure

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

While writing a function that includes placing grid lines at the same position as the axis ticks, I found that the axis* functions don't return anything. Thus I have had to copy the appropriate function, removing the call to axis() and adding a line to return the tick positions. Is there a more elegant way to determine the tick positions on an axis? Thanks. Jim (normally bitwrit at
