In the graph shown in your URL above, the xlab and the ylab appear in their entirety, unbroken. So does the one plotted in the middle of the graph. I get the same when I run your code. The texts you plotted at the first and third of the positions (i,i) also are not (I think) unbroken -- they are simply not entirely visible. The one at bottom left is missing its start "aReallyLongSt", and the one at top right is missing its end "eHowItBreaks". These apparent truncations arise because the beginning of the first, and the end of the second, are outside the plotting area, and so when the postcript() driver puts a BoundingBox at the border of the potting area this has the effect of "clipping" these strings when they are displayed. The apparently "broken" strings in the PostScript code you quote below are perfectly normal in PostScript. When dealing with text in a variable-width font, a PS driver will typically split continuous text into chunks, to allow for effects like kerning (or other adjustments of spacing) between the chunks. You will note that all five instances of the string are split in the same places, despite the fact that at least three of them come out perfectly (according to the graph on your URL). So nothing is wrong. You will have to adjust the extent of your plotting area, or adjust the "pos" or "just" of your (i,i) labels, to be able to see them in their entirety.
