[R] repeated searching of no-missing values

Perhaps... But plyr works only on **basic** data structures, and I referred
to all **possible** data strucures (deliberately); so I stand by my
statement and note that you did not contradict it.

I disagree with this claim: I think it is possible to create a logical
and consistent set of functions for working with the all basic data
structures in R, and this is what I have attempted to do with my plyr
package.  Any remaining inconsistencies are due to my failings, not
the fundamental difficulty of the task.
