a incremental backup copies everything since the last incremental
a differential copies everything since the last full.
rsync is NOT a backup system, its just a incremental file copy
with the full/incremental/differential approach, a restore to a given
date would need to restore the last

multivariate integration and partial differentiation
Could somebody share some tips on implementing multivariate integration and partial differentiation in R?
For example, for a trivariate joint distribution (cumulative density function) of F(x,y,z), how to differentiate with respect to x and get the bivariate distribution (probability density function) of f(y,z). Or integrate f(x,y,z) with respect to x to get bivariate distribution of (y,z).

How to solve differential and integral equation using R?
Hello,
I want to know if there are some functions or packages to solve differential

numerical differentiation in R? (for optim "SANN" parscale)
Dear R users,
I am running a maximum likelihood model with optim. I chose the
simulated annealing method (method="SANN").
SANN is not performing bad, but I guess it would be much more effecive
if I could set the `parscale' parameter.
The help sais:
`parscale' A vector of scaling values for the parameters.
Optimization is performed on `par/parscale' and these

symbollic differentiation in R
Hi all,
I wrote a symbollic differentiation function in R, which can be downloaded
here:
http://www.econ.upenn.edu/~clausen/computing/Deriv.R
http://www.econ.upenn.edu/~clausen/computing/Simplify.R
It is just a prototype. Of course, R already contains two differentiation
functions: D and deriv. However, these functions have several limitations.
They can probably be fixed, but

Differential Equations
Hello!
I would like to know if R can solve Differential Equations...
I don't think so because, in my point, I see R like a Statistical System, not a
Math System. Am I wrong?
Thank you very much.

Rsync and differential Backups
Hi list,
how to perform a differential backup using rsync?
On web there is a great confusion about diff backup concept when
searched with rsync.
Users says diff because it copy only differences. For me differential is
backup from last full backup.
Other users says that to perform a differential backup I must include in
rsync command: --backup --backup-dir=/some/path but from manual page of

Differential: accepted but not closed revisions
Hi!
There are a lot of accepted but not closed revisions in Differential.
Many of them were actually committed, but without Differential
revision link or when it was specified in wrong way.
I think will be good idea to create script which will match committed
revisions with those in Differential: file list should be same and
hashes of changed line could be calculated for each file. In case of

Species accumulation curves with differential sampling effort
Hello! I'm a PhD student working with coral reef fish diversity in Mexico.
I want to do species accumulation curves but I have differential sampling
effort for each "sample".
Do you know or have developed an R script that consider the differential
effort of each sample?
PRIMER and other programs use each pack of species as a replica without the
possibility of telling the program that

Differential backup
Hello,
I have got three folders:
- /home/backup/2008-10-20 - place for differential backup
- /mnt/for_backup - folder with files for backup
- /home/backup/2008-10-01 - place where the last full backup is
My question: is below command prepared correctly to make differential
backup?

That's my point. "find" doesn't do that and na?ve implementations of
the original suggestion are likely to do work poorly. For no reason.

Solution to differential equation for nls function
Hello,
I am trying to find the analytical solution to this differential equation
dR/dt = k1*R (1-(R/Rmax)^k2); R(0) = Ro
k1, k2, and Rmax are parameters that need to fitted, while Ro is the
baseline value (which can be fitted or fixed). The response (R) increases
initially at an exponential rate governed by the rate constant k1.
Response has a S-shaped curve as a function of time and it

I also find the "Reviewed by" tag useful (as well as the review link), for
the same reasons. In fact, I don't even use arcanist to push commits, so I
do it all by hand, and only include the "Reviewed by" and "Differential

What functions exist for differentiating a numeric vector (in my case
spectral data)? That is, experimental data without an analytical
function. ie,

differential equations
Hi, Does somebody knows of the existence of a library of functions
for solving differential equations, I need a solver for a system of non
linear first order differential equations. I think there was something
in IMSL but that was a long time ago and probably there are some
new algorithms in the new now.
Thanks for any pointers.

Differentiation
Hi,
Could anyone tell me what is the command used in R to do
1. Differentiation
2. Newton Raphson method (Numerical Analysis in general...)
Are there any packages separately for this?
Thanks for your help!
