Dear Gabor,
Thank you very much for your help!
I'm now using your suggestion with my data.
May I ask a stupid question?
The output's index now has format "2009-10-14". How can I transform it back
into original "10/14/09" and use this in a zoo object?
Regards,
Sergey

I now have three ways to achieve my goal:
1: rep(list(list()), 3)
2: replicate(3, list())

Does anyone have suggestions? Thanks!

Try this:
plot(0, main = ~ g(sigma * "|" * alpha))

Hi Maram,
How about this?
plot(1, ylab = expression(sigma*"|"*alpha))

Hi all,
I want the y-axis label to be ( in symbols)
g(sigma given alpha)
where given is the conditional sign.
I've tried
ylab=expression(g(sigma|alpha)))
but it gave me
g(|(sigma,alpha))
where the sigma and alpha are in greek but the conditional sign is misplaced
(before the bracket)
Any help woul
Josh,
One way would be to convert the numeric vector to a character and use
the function substr(). Following code returns a numeric vector with
the 2 first digits of every element.

Try this:
library(zoo)

# create a day sequence, dt, with no missing days
# and create a 0 width series with those times.
# merge that with original series giving original

Dear r-helpers!
How can I integrate other distances (in the form of a dist object) into
function metaMDS? The problem: metaMDS needs the original data.frame for the
calculation and only the default distances of function vegdist are allowed.
Any suggestions are greatly appreciated!
Thank you,

Alexandre,
Let me add two small points to Ted's exposition:
1. you can use the extractor function coefficients(),
or just coef() on the summary:
coef(summary(regression))
which will also give you the matrix of estimates, etc.
2. You will find that using the function str() often is

Can you give us a reproducible example of R commands that cause these messages
on your system? Like by creating simulated data.frames, opening several
devices, etc?

I'm translating some MATLAB code into R and have not found a simple
equivalent of the function R = subs(S,old,new).
I have, for example, a matrix such as this
mx<- function(){
matrix( c(0, f1, f2,
s1, 0, 0,
0, s2, 0), 3,3, byrow=T)
}
and a matrix of data
dat<-matrix(c(1
