Hello

I believe the help for the 'text' function (which places text on graphs)
is wrong, specifically for the 'pos' variable. I did some tests to place 
some text,

e.g. text(2000, -3, "This is a test at (2000, -3)", cex = 0.5, srt=90, pos=4)

With no pos, the (vertical) text was centred at the specified co-ordinates.
When pos=1, it was to the right
pos=2 -> below
pos=3 -> left
pos=4 -> above and to the right.

This disagrees with what the online help says:
"Values of '1', '2', '3' and '4', respectively indicate positions
below, to the left of, above and to the right of the specified coordinates."

Thanks
