Subject: [Rd] Is text(..., adj) upside down? (Or am I?)
Message-ID: <s885d468.016@tedmail.lgc.co.uk>

?text says
    "'adj' allows _adj_ustment of the text with respect to '(x,y)'.
     Values of 0, 0.5, and 1 specify left/bottom, middle and
right/top,
     respectively."

But it looks like 0, 1 specify top, bottom respectively in the y
direction.

plot(1:4)
text(2,2, "adj=c(0,0)", adj=c(0,0))
text(2,2, "adj=c(0,1)", adj=c(0,1), col=2) #the red one's below the
black one...

#x-adj is OK
text(3,3, "adj=c(0,0)", adj=c(0,0))
text(3,3, "adj=c(1,0)", adj=c(1,0), col=2)

[I am using r 2.7.1 in windows; adj behaviour is consistent in 2.6.0ff
and for expressions as well as text]

Perhaps a two-word correction to ?text ?
