And there are over 120 packages providing access:
CITAN Cubist GOSim KernSmooth MASS MSBVAR Matrix NetComp PMA PopGenome
QuACN RCurl RODBC RTextTools Rcpp Rigroup Rlabkey Rmosek Rmpfr Rook Rserve
Runuran SASxport SMCP SoDA TraMineR XML actuar adaptivetau akima aster
aster2 bcv bda blme boolfun bstats canvas caret catnet cgh chron class

rngWELL robustbase rpart rphast rrp rtfbs sde sensitivityPStrat sp spatial
spdep spsurvey spt tree tripack uncompress vines xlsReadWrite xts yaml zoo
Matrix and lme4 is the prototypical example by R Core, MASS also provides
something. I'd probably start with zoo and xts ...
PS Rcpp et al don't do it as you can't register C++ routines IIRC.
