extracting and restricting coefficients
Hi
I want to fit two equations simultaneously
EQ1<-Y1~X1+X2
EQ2<-Y2~X1+X2
eqsystem<-list(Y1HAT=EQ1,Y2HAT=EQ2)
fitols<-systemfit(eqsystem,
method="OLS", data=BB)
How do I get coefficients for the first equation? R code
How do I restrict coefficient of X2 in the first equation (say , restrict it to less than zero). R code
Your help is
appreciated.

Integration in R
Dear R-users,
I am facing problem with integrating in R a likelihood function which is a
function of four parameters. It's giving me the result at the end but
taking more than half an hour to run. I'm wondering is there any other
efficient way deal with. The following is my code. I am ready to provide
any other description of my function if you need to move forward.

How to compute the density of a variable that follows a proportional error distribution
Hello,
I am trying to compute the density of a variable k that is either (1)
Normally distributed; (2) Log-Normally distributed; or (3) follows
proportional error distribution. I tried to search R-help and the answer for
normal distribution was easy to find (please see 1c). I am not sure if my
formula for dlnorm is correct (please see 2c below)? I really don't know
what function to use for the

fixes for quota support on NetBSD
Hi!
dovecot-2.2.13 already has quota support for NetBSD, but it's buggy.
The attached patches by Manuel Bouyer <bouyer at NetBSD.org> fix the
issues.
There is one thing that's not nice in them: one include is now for
"/usr/include/quota.h" since dovecot comes with its own file "quota.h"
which is earlier in the search path. Perhaps dovecot's copy can be

deSolve question
Dear All,
I like to simulate a physiologically based pharmacokinetics model using R
but am having a problem with the daspk routine.
The same problem has been implemented in Berkeley madonna and Winbugs so
that I know that it is working. However, with daspk it is not, and the
numbers are everywhere!
Please see the following and let me know if I am missing something...
Thanks a lot in advance,

Convert factor to "double"?
Hi!
I'm reading a tab-seperated CVS file with:
test1 <- read.table("data.txt", header=TRUE)
It's in the following format:
Date_Time qK qL vL vP ...
0 30 22 110 88 ...
...
(BTW: It seems to me R shifts the column descriptions by one.)
Anyway, I would like to Fourier-transform one column. So I say:

R-alpha: New Incomplete Beta Function
Here is a drop-in replacement for the R incomplete beta function.

It is a slightly modified version of the cephes library one from
Netlib. In the few cases I tried it seems to give at least 14
digit agreement with the one in S-PLUS (its hard to get more).
I'm not sure what performance is like. I'd like to know if it

Help a newbie (please!): Samba and WinXP in a non-PDC environment
Hi all... looking for some assistance with my first Samba setup.
The setup: On a small (five-computer, mixed Win2k and WinXP pro) LAN, I'd

no PDC, no individual user directories or password protection -- just a big

tftpd server S not responding
A STATEFUL firewall with ?ip any any? can and will still block asymmetric
communications due to the firewall keeping track of state (hence tha name
stateful firewall).
Tcpdump on your servers /other/ NICs and you?ll see the tftp traffic
leaving your server on some other NIC (probably on with the default route).
The upstream firewall will then block the tftp response if it never saw the

r package to solve for Nash equilibrium
Is there an r package out there that solves for pure strategy* Nash
equilibrium of a two-person game*? A search for Nash equilibrium in r
provides a link to the *GNE* package which solves for the Generalized Nash
equilibrium. But what I would like to solve is a pure strategy Nash
equilibrium.

Generating bootstrap samples from a panel data frame

Dovecot-lda permission errors or maybe authentication errors?
I am a new dovecot user who recently transitioned my old mailserver to a new
CentOS/Postfix/Dovecot system. I am running a simple configuration with
about a dozen system users and Maildir folders. The e-mail setup seems to
be running fine when I use the default local-delivery-agent in Postfix.
However, I am trying to use the dovecot-lda instead so I can take advantage
of the sieve functionality.
