--==_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

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

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, 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)

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
