What R packages are you aching to see?

Are there any R packages that don't yet exist that you wish existed? What kinds of things do you wish were easier to do in R? What things do you wish were faster to do in R?

This might be a place for package writers to get ideas or it might just be a place for some people to actually learn what is out there in the R community.

It would be interesting to see a package for R similar to python's pep8 package. There would need to be an agreed upon coding convention for that to work. Hadley might be opinionated enough and have enough sway with the community to do something like that but as it stands I doubt we'd see something like this in the future.
