Hi.
I have been using the splines package for my work, in particular, the bs()
function and associated predict() method. I now find myself in need of the
derivatives of this beast.
In the man page for predict.bSpline I found `predict(object, x, nseg=50,
deriv=0, ...)' but alas this is not impl
Again, I have the same attitude as Gabor. I don't need to know the
real identity of a poster, if they ask a sensible question (which
may well be elementary).
As a contribution to the discussion, may I point out that many people

Hi,
I would like to see how model.matrix expands factor column to a set of dummy
columns. I think that is done int .Internal(model.matrix(t, data)) which is
called from model.matrix.default. But I have not idea how I can look at this
function. How can I get to such internal functions?
Thanks s

Thanks for your suggestion, Carl. Actually I am looking for a series
of functions like these
exp(-x)*.5^x

where(.5,.4,.3...) are from the coming results.
Those are not really functions but rather
If your series is nearly regular, that is it is regularly spaced
except for a few missing points then as.ts(z) will convert it to a
regular ts series and as.zoo(as.ts(z)) does that and converts it back.
You may need to add back the class. For example see:

I'm stumped after an hour or so reading about subscripts in panel.xyplot.
Apparently the panel function is executed for each subset of data in the
main dataset (specified by the conditioning variable, 'site' in my

corresponding row n

Hello everyone,
