I thought that's nice, because I wanted to have tick marks and tick labels inside and the axis title outside. But:
plot(z, las=1, tck=0.01, mgp=c(1,-1.5,0))
Warnmeldungen: 1: In plot.window(...) : `mgp[1:3]' are of differing sign 2: In plot.xy(xy, type, ...) : `mgp[1:3]' are of differing sign 3: In axis(side = side, at = at, labels = labels, ...) : `mgp[1:3]' are of differing sign 4: In axis(side = side, at = at, labels = labels, ...) : `mgp[1:3]' are of differing sign 5: In box(...) : `mgp[1:3]' are of differing sign 6: In title(...) : `mgp[1:3]' are of differing sign
par(las=1, tck=0.01, mgp=c(1,-1,0))
Warnmeldung: In par(las = 1, tck = 0.01, mgp = c(1, -1, 0)) : `mgp[1:3]' are of differing sign Was there a recent change, couldn't find anything useful searching the web. Regards, Cornell
Well, it's only a warning, making you aware of a possibly unintended par setting. Warnings are good things but if you don't want to see them, they can be suppressed. Certainly not a bug.
Hmm, then again, I tend to agree with Cornell that there are a bit too many cases where mgp[1:3]' would sensibly have differing sign, compared to cases where it is a mistake. In addition to internal tick marks and labels, there are also cases where the whole axis is shifted into the plot area. I'd more likely use axis(pos=...) for that, but still.
