Hello.
I would like to estimate the correlation coefficient
from two samples with Bootstrapping using the
R-function sample().
The problem is, that I have to sample pairwise. For
example if I have got two time series and I draw from
the first series the value from 1912 I need the value
from 1912
This should do it for you:

Hello all,
I was wondering if anyone knew how to construct a multiple line graph on R,
where there are 2 (or more) sets of data points plotted against some x axis of
data, and you can draw a line on the graph connecting each set of data points.
For example:

The simple way is to enclose it in a 'function' and pass parameters.
Assuming that you have the same number of parameters, then the

mtext( expression( bar(x) == 3.07) )
but you can also simply 'paste' things:
text(0,0,labels=expression(paste(bar(omega), " = 1")),srt=90)

Sorry, I answered too quickly.
It worked with the "simplified" example I provided but not with
non-regular intervals in x:
x<-c(-45,67,131,259,347)
y <- c(0.31, 0.45, 0.84, 0.43, 0.25)
plot(x,y)
lines(spline(x,y, method='n', n=250))
#or:
lines(predict(interpSpline(x, y)))

Hello,
I would like to create a mtext. The argument 'text' should combine the
mathematical expressions 'bar' with the plain text ' = 3.07'. Is that
possible?
mtext(text=expression(bar(x)) ...)
' = 3.07'
Thanks for any ideas

I am going to fit my model with R-2.5.1.tar
my model is y=fixed effect+b(x) and I have three column in my
data file (y a x) and about 20 observation(y)
but I had some problems. I was wondering If you could help me
the error massage is:
> res <- read.table("pro.sdf")
> fm <- glm(y=A+x,data=res)
Both worked, thanks!

Hi All,
I'm trying to run generalized singular value decomposition (GSVD) function
from LAPACK library. Basically my problem is that I can not run it for large
matrices, I get a memory error.
I'm using R 2.5.1. I tried this on intel centos5 machines with 2 GB memory
and 8 GB memory. I have u
Hello Ravi,
I was also trying to write down such a calculation but I did not manage (I
didn't use diff(x)).
Thank you for the solution.
