Dear Author
I have run into a trouble in using chron package
The data frame: a

Well, the na.action component (which may or may not be present in an lm
object) is *not* what na.action is documented to give:
Value:
The action which will be applied to 'object' whenever 'NA's are
not desired.
So this needs some re-working, and it is not just lm objects that have
chron represents times as a fraction of a day using doubles so seconds
cannot necessarily be represented exactly thus this is an example of

Try this:

I am working on embedding R into some visualization research programs. Can
any point me to a collection of embedded and standalone R/C/C++ examples? The
documentation is to terse for me to figure out how to develop this and I am
looking for some simple examples to study.
Thanks and best
You might also want to look at existing visualisation applications
that connect with R:

* http://rosuda.org/mondrian
* http://rosuda.org/software/Gauguin/gauguin.html
to name a few.
