Hi
We have a few questions regarding the use of the isoMDS function.
When we run isoMDS function using 60,000 x 60,000 data matrix,
we get the following error message:
cmdscale(d, k) : invalid value of 'n'
Calls: isoMDS - cmdscale
Hello,
Can I get help? I have the attached kind of material and I should create a
time-dependant covariate from the variate Optime? I have tried using
survsplit function but I don't know exactly how to do it. Or I can't get it
to work. How can I split every id's follow-up time into two rows

Dear Mr Michael,
Thanks a lot for your guidance. The pdf file describing VGAM package has
mentioned 'frechet' in the example, so I got the error.
Regards

Dear Ms. Gobin,
There would appear to be a typo in the package manual that appears on
CRAN. Doing ?Frechet (it would be nice to have this aliased also to
frechet) points you immediately to frechet. With frechet2
substituted for frechet your code, everything works.
cheers,
Rolf Turner
You avoid the call to cmdscale() by supplying your own starting configuration
(see the manual page for the y= argument). You could still hit other barriers
within isoMDS() or insufficient memory on your computer.

I wish to simulate the following stochastic process, for i = 1...N
individuals and t=1...T periods:
y_{i,t} = y_0 + lambda Ey_{t-1} + epsilon_{i,t}
where Ey_{t-1} is the average of y over the N individuals computed at time
t-1.
My solution (below) works but is incredibly slow. Is there a faster

Ah — OK, N=20, I did not catch that. You have nested for loops, which R is
known to be exceedingly slow at handling — if you can reorganize the code
to eliminate the loops, your performance will increase significantly.

I find that representing the simulated data as a T row by N column matrix
allows for a clearer and faster simulation function. E.g., compare the
output of the following two functions, the first of which uses your code

R on Windows uses the Olsen timezone database, a copy of which is stored with R
in the Program Files directory (e.g. R/R-3.1.1/share/zoneinfo). You could
update the file yourself if you can find a corrected version, or download an
updated version of R.
Thanks Jeff Newmiller, it is working now.
I would like to know, the same kind of configuration can be done in Linux
and Solaris platform.
Instead of R is mapping to operating system(/usr/share/. /usr/share/lib/)
zoneinfo directory.
Thanks

Working now... after what action?
AFAIK on *NIX systems R uses the OS installation of the Olsen database, so on a
fresh login R should pick up any OS update you have installed.

You probably need to recompile R.

Loops are not slow, but your code did a lot of unneeded operations in each
loop.
E.g, you computed
D$id==i D$t==t
for each row of D. That involves 2*nrow(D) equality tests for each of the
nrow(D)
rows, i.e., it is quadratic in N*T.
Then you did a data.frame replacement operation
