Actually it's highly discouraged to do that, since you lose control of the

It's much wiser to use a vector or a list to do that.

Hi R users,
I am new to R and am trying to merge data frames in the following way.
Suppose I have n data frames each with two fields. Field 1 is common among
data frames but may have different entries. Field 2 is
now that's beautiful! :-)
Many thanks,
David.
Try this where DF1, DF2 and DF3 are the data frames:
L - list(DF1, DF2, DF3)
merge.all - function(...) merge(..., all = TRUE)
Reduce(merge.all, lapply(L, function(x) aggregate(x[2], x[1], toString)))
The last line gives this:

Are there implementations of, e.g. Neville's algorithm, for interpolating
polynomials through some data points? Nevilles' is an improvement on
Lagrange interpolation. And how about interpolating rational functions? I
could not find anything at rseek.org or at crantastic.org.
thanks

Hi everyone,
I'm involved in a discussion with a colleague. He suggested a sample
design for a finite-sized process that (to all intents and purposes)
involves tossing a coin and examining the unit if the coin shows
Heads.
I should emphasize that we're both approaching the problem from a
Thanks for your very constructive and helpful tips, Peter and Ted!

Neville's algorithm is not an improvement on Lagrange interpolation, it is
simply one way of calculating it that has some useful properties. The result
is still the Lagrange interpolating polynomial, though, with all its flaws.
Implementing Neville's algorithm is fairly easy using the PolynomF

Superb Gabor,
Though I dont know what is happening, but yes it is workin and without fail.
Thanks

I'm a new user of R, and trying to display the result of a PCA data set
with biplot(). Biplot() draws the projections of data points to the
first two principal axis with a text level (I guess it is the name of
the data points). This makes the picture very crowed. I tried to go
