Dear R-Devel,
I have had it in my mind for some time now that a Task View related to
R and education might be a good thing.
There are currently 19 Task Views, covering a broad spectrum of
general topics for which R may be used. The homepage lists 64 books
related to R, and several of them have a

I made a couple of a changes from the previous version:
- don't use functions anyMissing or notSorted (which aren't in base R)
- don't check for dup.row.names attribute (need to modify other functions
before that is useful)
I have not tested this with a wide variety of inputs; I'm assuming tha

There needs to be a physical relocation of servers tomorrow (email and

(hopefully not more).
I'll be out of email reach myself, for the same reason.

In R2.7.1, the first line of the body of png() reads:
checkIntFormat(filename)
This should really be:
if (!checkIntFormat(file))
stop("invalid 'file'")
Otherwise a command such as png("foo%s.png") causes R to crash (see bug
#10571).

If you are concerned about performance you definitely do not want to use
shared R, not a shared BLAS.
