[R] stretching text vertically

I'd like to stretch a plotted character vertically, to create a 
"sequence logo".

Is there a parameter to allow stretching text() output vertically or 
squeeze horizontally?

I know about Oliver Bembom's seqLogo library, but this generates a 
sequence logo plot using a separate bitmap device. I want to recreate 
the sequence logo *inside* an existing plot.

Alternatively, is there a way to embed one plot inside another?

I could use imagemagick outside R to 'montage' separate bitmaps, but 
then the sequence logo is going to be very difficult to align (base for 
base) with the plot I'm trying to join it to.

Thanks for any tips,
