nls segmented model with unknown joint points
...perhaps eventually in nlme. I can fit this model in sas (see
below, joint points to be estimated are a41 and a41), but am unsure how
to specify this in the nlm function. I would really appreciate any
suggestions or example code. Thanks a lot. -andy
proc nlin data=Stems.Trees;
params b41=-3 b42=1.5 b43=-1.5 b44=50 a41=0.75 a42=0.1;
term1 = (b41*(x - 1) + b42*(x**2 -1));
if (a41 - x) >= 0 then
term2 = (b43*(a41 - x)**2);
else
term2 = 0;
if (a42 - x) >=0 then
term3 = (b44*(a42 - x)**2);
else
term3 = 0;
model y = term1+term2+term3;

Differential Equations Using R?
To whom it may concern,
I am a student at Macaleste College, and next semester Macalester
is going to offer a course for CellBio that is mainly statistically based.
For the most part the students will be using R for analysis. The problem is
there will be some simple differential equations for the students to solve.

Sv: Sv: Ordinal Regression
Dear Peter.
I guess you know that Jim Lindseys code include nordr and ordglm in library gnlm - I attach the htmls which do various linear and nonlinear ordinal regressions - exemplified with just the data mentioned, McCullagh (1980) JRSS B42, 109-142. I had it work very fine.

u32 mark hashing
Hi,
is it possible to use firewall mark as an u32 hash key? What i understood
from the source code is that only 32-bit number inside of the packet can
be used as a hash key, though fw mark can be matched using u32 match(with
2.6 kernel and recent iproute2 version).
Thanks,

Updates for xlsReadWrite (1.5.3) and xlsReadWritePro (1.6.1/3)
...- cells: pick single cell values and give them back as a vector or as a
data.frame (the latter is new, type will be determined for each
cell individually)
- range: read ranges either by name or by a numeric 4-elem-vector
(R1,C1,R2,C2)
(A1 style, i.e. 'A1:C3', 'Sheet2!B42' could eventually be added here).
o xls.sheet, NAMEORINDEX argument renamed
- 'nameOrIndex' becomes 'sheet' and the default is the first/active sheet
(depends if file is a physical file or an xls-obj)
- 'copyAndInsert' action copies from the active sheet
o xls....

[RFC, PATCH 4/24] i386 Vmi inline implementation
Macros to use VMI calls from assembly and C languages are introduced.
The macros are quite complex, but the end result is rather impressive.
The result is that when compiling a VMI kernel, the native code is
emitted inline, with no function call overhead, and some wiggle room
for register allocation. The hypervisor compatibility code is emitted
out of line into a separate section, and patched

Strange problem with HTB
Hi list,
I''ve got quite a strange problem with htb. I have following
configuration: dual core athlon, two intel e1000 nics - eth1 is
connected to lan and has private ip, eth0 is connected to our isp and
has public ip (so there''s nat on eth0). There is practically same htb
configuration on both interfaces, only the filters are different. On
eth1, packets are classified by their
