Hi Uwe,
Thanks for your mail.
I see it different: yes, Left / right adjustemnt seems to be perfectly OK.
But at axis 1 with las=1, it's not Left / right adjustement what is needed
here. Here the text needs to be right adjusted, and the (one) adj= par
should determine the vertical alignment.
I don't think so. Things are perfectly clear for the user if adj controls adjustment in reading direction independently from the las setting - and a second value specifying perpendicular adjustment.
> It is a bit confusing, but for
mtext, the distance to the axis is done via line= and adj= moves ALONG the
axis, whatever las= says.
No, adj moves not always along the axis:
plot(1:10)
mtext("Hello", 3, at=5, adj=0, col="red")
mtext("Hello", 3, at=5, adj=1, col="green")
mtext("Hello", 3, at=5, adj=0, col="red", las = 2)
mtext("Hello", 3, at=5, adj=1, col="green", las = 2)I agree that it would be more flexible and logical to also have the 2 element form of adj=c(horizontal, vertical) here, but I fear that this creates a lot of incompatibilities with existing code and with S+.
My suggestion was different: using a new argument padj to be more flexible.

Left / right adjustemnt seems to be perfectly OK.
The thing that matters is centering "several lines" to the specified ("at=") location.
In fact, mtext() is not centering but bottom-aligning by adding a negative distance that looks OK for one line in the default font size, but not in most other cases.
Hence this is the same as Paul Murrell's PR#1659 ("mtext() alignment of perpendicular text"). Fixing this, and/or improving mtext()'s "adj" argument to accept 2 dimensions is desirable, but might be not that easy... I'll take a look during the next days, but nothing promised.
