No, not yet. But mtext logically is oriented relative to its axis. And it
should behave consistently relative to its axis.
Whichever solution is choosen finally, I think it is important, that the default parametrisation will handle multi-line labels such that they are centered around at= and aligned at line=, whatever side= and las= are choosen. Beeing forced to tweak with adj= / padj= depending on side= / las= would be very impractical. This "requirement" is easily fullfilled with default adj=0.5 if we have mtext's adj= always move along the axis. With a adj= / padj= solution, different defaults would be needed for the different combinations of side= and las=.
Might be nice, but I don't think we can easily change that much in mtext()'s behaviour. It is widely used in graphic functions and changing the defaults too much will break an incredible amount of code (if someone changes mtext() in that manner, I'll unsubsribe from R-help for half a year ;-)).
How does it S+?
The outdated S-PLUS 4.5 behaves like R does, but the logic is different since you have to specify srt rather than las.
