[BioC] Drawing multiple sequence logos with seqLogo?

[Wolfgang Huber]

Hi Nenad

grid graphics, and in particular the "seqLogo" function, are in fact a 
lot more powerful for combining with other graphics elements (including 
a title, or multiple logos in one plot) than R's default graphics, 
"par", etc. The only possible drawback is that one needs to read the 
"grid" documentation to understand its viewport concept.

Try:
   browseVignettes()

and search for "Introduction to grid" and perhaps "Working with viewports".

	Best wishes
	Wolfgang

PS: always remember to be specific about the name of the package (and 
version) that you refer to.

PPS: nothing is impossible with R.
