[R] Problem with text() and pdf()

[Prof Brian D Ripley]

My guess is clipping.  R clips in pdf() by omitting the whole text if any
part of it is clipped.  Try xpd=TRUE.

BTW, this is a function of R's graphics engine and not of the PDF device
per se: it happens that X11 and PostScript support clipping, and PDF does
not (at the level used).
