Problem in Fitting model equation in "nls" function
Dear R users,
I am struggling to fit expo-linear equation to my data using "nls" function. I am always getting error message as i highlighted below in yellow color:
### Theexpo-linear equation which i am interested to fit my data:
response_variable = (c/r)*log(1+exp(r*(Day-tt))), where "Day" is time-variable

nlme problems
I'm maximising a reasonably complex function using nlme (version
3.1-65, have also tried 3.1-66) and am having trouble with fixed
parameter estimates slightly away from the maximum of the log
likelihood. I have profiled the log likelihood and it is a parabola
but with sum dips. Interestingly changing the parameterisation moves
the dips around slightly. Unfortunately the PNLS step is

save() object w/o all of the loaded environment
I have two packages, one that does the actual work (SC) and the other
a Tcl/Tk UI (SCUI) that invokes methods within the former. Within the
SCUI's invocation method, I save an object returned from SC, the
results of a long-running method.
Now the object is completely described by the SC package. Unfortunately,
any attempt to load the object (in a fresh R session) fails as below.

Fixed size permutations
I'm using functions to return a matrix of all permutations of a
specified size from a larger list for predictor selection.
For each predictor size I use a seperate function like this:
bag2 <- function(n) {
rl <- c()
for (i1 in seq(n)) {
for (i2 in seq(n)) {
if (length(unique(c(i1,i2)))==1) {next}
rl <- cbind(rl,matrix(c(i1,i2)))
}
}

Binding one column of characters into a dataframe factors other numeric columns
Hi all,
I searched through the archives, but couldn't find a fix...
Basically, I've got a bunch of numeric vectors and one character vector that
I want to bind into a data frame. When I include the character vector as a
column in the data frame, all the numeric columns get factored in the data
frame, which makes it tough to call those columns for calculations later on.
I've tried

ListenAdress Exclusion
I was wondering what everyone's thoughts were on a simpler way to exclude
addresses from having listeners on them.
I know a lot of people have multiple subnets, especially larger
corporations.
Some networks are non-route-able, and therefor unsuitable for use with SSH,
aside from communication between other servers on the same subnet.
Given that we may want to exclude those non-route-able

WinVC v1.11 released (bug fix for Europe)
European users that use a comma as a decimal point were experiencing a
BSOD (blue-screen-of-death) using the new OggInfo.exe support. This was
due to OggInfo.exe returning a period (.) in numbers regardless of
windows regional settings.

ED50 from logistic model with interactions
Hi,
I was wondering if someone could please help me. I am doing a logistic
regression to compare size at maturity between 3 seasons. My model is:
fit <- glm(Mature ~ Season * Size - 1, family = binomial, data=dat)
where Mature is a binary response, 0 for immature, 1 for mature. There
are 3 Seasons.
The Season * Size interaction is significant. I would like to compare the
size at 50%

[PATCH 0/3] WIP readline escaping functions
From: Maros Zatko <hacxman@gmail.com>
Auxiliary functions for readline to support space character escaping
in filenames in future.
Escaping function is taken from fish.c (used to be parse_quoted_string)
plus its un-escaping counterpart. There are a few tests for both.

range and intersection
Hi:
I have a two large files (over 300K lines).
file 1:
Name X

UAE 94
File 2:
Name X Y
UK 140 180
UK 195 240
UK 304 340
....
I want to select X of File 1 and search if it falls in range of X and
Y of File 2 and Print only those lines of File 1 that are in range of
File 2 X and Y
How can it be done it

Its possible the rL (LLVM) had be added as the repository in the review on
creation rather than rCFE, if thats the case then the herald rule "H270" is
going to fire because it see the repository in the review, so add LLVM

Is rl broken?
Greetings,
I cvsup'd and rebuilt a FreeBSD 4.8 system last Friday after receiving the
realpath security advisory. The machine is remote and the NIC uses the rl
driver. After booting the machine I had no network connectivity. The
person at the remote site says the boot was normal and he could see that the
NIC was properly configured but he could not ping it and I could not login.

LoopVectorizer -- generating bad and unhandled shufflevector sequence
Hi,
I have experimented with enabling the LoopVectorizer for SystemZ. I have
come across a loop which, when vectorized, seems to have been poorly
generated. In short, there seems to be a completely unnecessary sequence
of shufflevector instructions, that doesn't get optimized away anywhere.
In other words, there is a shuffling so that leads back to the original
vector:

R-beta: odd result with sum?
I am using R 0.49 and I did not see this in the archives:
Given sum() defaults to na.rm = FALSE, should both of these results be NA?
> sum(c(1,NA))
[1] NA
> sum(c(NA,1))
[1] 0
