Hey Folks, I’m rather tired tonight, but I think I’m really seeing
what I’m about to report. I was working on some plots (on the Quartz
device), and ran into what seemed to be discontinuities in what
should have been nice smooth plots. Then, I tried the following:
plot(c(1:100), c(1:100)) # plot of individual points looks OK
plot(c(1:100), c(1:100), type = "l") # produces a line with breaks/
gaps
plot(c(1:100), c(1:100), type = "l", lty = 3) # dotted line with
breaks/gaps
If instead I direct this to a pdf file with, e.g.,
pdf("test.pdf")
plot(c(1:100), c(1:100), type = "l", lty = 3)
dev.off()
There are no gaps in the "line".
Am I just too tired to see what's going on here, or was a new problem
introduced along with the fix for the slow drawing problem in the
patched R
2.7.0?
Mea culpa, indeed, it was introduced by the fix (it was plotting only
half the segments in each batch - blame Apple's documentation on
that... :P). I have fixed that now (use SVN or wait for tonight's
build).
Thanks,
Simon
