There is the hexbin package available through Bioconductor. It uses
grid graphics I believe.
If you want a base graphics solution, or just more hands on control (and
using only CRAN packages), then check out the last example on the help
page for the my.symbols function in the TeachingDemos package.
For sp objects, see the "hexagonal" type in spsample(), the low-level
sp:::genHexGrid(), and HexPoints2SpatialPolygons():
hpts <- sp:::genHexGrid(dx=0.1, ll=c(0, 0), ur=c(1, 1))
pols <- HexPoints2SpatialPolygons(SpatialPoints(hpts))
plot(pols)
Hope this helps,
