R Without Hadley Wickham

Tim Hopper asked on Twitter today:

#rstats programming without @hadleywickham’s libraries is like ________ without _________.

Some of the replies were:

• (skydiving, a parachute)
• (gouging your own eyes out, NULL)
• (dentistry, anesthesia)
• (shaving, a razor)
• (internet shopping, credit card)

Clearly there’s a lot of love out there for Hadley Wickham’s R packages. I’m familiar with his ggplot2 graphics package, and it’s quite impressive. I need to look at his other packages as well.
