RFC: a "safe" uniroot() function for future R
...--------------------------------------------------------------------
The help file says
?unirootS()? is a ?safe? version of ?uniroot()?, built on
?uniroot()?, also useful as drop-in replacement of ?uniroot()? in
some cases. ?Safe? means searching for the correct ?interval =
c(lower,upper)? if ?sign(f(x))? does not satisfy the requirements
at the interval end points; see the ?Details? section.
We've had this function, called safeUroot() in our package
copula for a while now, where an earlier not-exported version
has been in my package nor1mix even longer.

(hpa-tftpd] remapping with regular expression problem
...e problems during this tftp phase can be solved with the remapping feature
quite nicely like:
*converting filenames into absolute paths
*convert backslashes to slashes
One problem missing is to alter the case of the requested files. As the drivers in XP
are using a wild combination of upper and lower cases I prefer to convert the
complete BartPE directory structure to lower case and force hpa-tftpd to remap all
filenames in the BartPE directory only (for example /tftpboot/winpe) to lower case.
And that's where I'm stuck:
To avoid side effects to other tftp downloads from the same ser...

minor flaw in integrate()
Hi,
I noticed a minor flaw in integrate() from package stats:
Taking up arguments lower and upper from integrate(),
if (lower == Inf) && (upper == Inf)
or
if (lower == -Inf) && (upper == -Inf)
integrate() calculates the value for (lower==-Inf) && (upper==Inf).
Rather, it should return 0.
Quick fix:
### old code ###

Upper case vs lower case in printed and parsed MIR
I am confused about the rules for when upper and lower case letters should be used in MIR.
As an example our downstream target has upper case letters in its sub-register indices and as a result we cannot import exported MIR without manually 'lower casing' it first which is obviously rather annoying.

R stat functions do not work as stated on the mannual (PR#7419)
...I have been playing with R, release 2.0.1 for a week now and have detected =
that all stat functions related to distribution probabilities have the same=
problem:
1.- According to the manual the log.p parameter is always the last one.
2.- When you use the software, the last parameter seems to be lower.tail

On this example, I have used the Student T distribution. The result of this=

plotCI error when trying to omit upper or lower bars (PR#7764)
Full_Name: Volker Franz
Version: 2.0.1 (2004-11-15)
OS: Mac OSX / Debian
Submission from: (NULL) (84.58.8.232)
Hi there,
the new version of plotCI (Version: 2.0.3 of gplots) produces errors
if the upper or lower error bars should be omitted by passing NULL as
an argument. Older versions of plotCI had no problem with this. Here
is an example:
library(gplots)
means <- c(1,2,3,4,5)
upperw <- c(1,1,1,1,1)
lowerw <- c(1,1,1,1,1)
upper <- means+upperw
lower <- means-lowerw

qbinom returns NaN
Hi, All:
For most but not all cases, qbinom is the inverse of pbinom.
Consider the following example, which generates an exception:
> (pb01 <- pbinom(0:1, 1, .5, log=T, lower.tail=FALSE))
[1] -0.6931472 -Inf
Since "lower.tail=FALSE", Pr{X>1} = 0 in this context, and log(0) =
-Inf, consistent with the documentation.
However, the inverse of this does NOT recover 0:1:
> qbinom(pb01,1, .5, log=T, lower.tail=F)
[1] 0 NaN

pnorm how to decide lower-tail true or false
Hi to all,
maybe the last question was not clear enough.
I did not found any hints how to decide whether it should use lower.tail
or not.
As it is an extra R-feature ( written in
http://finzi.psych.upenn.edu/R/Rhelp02a/archive/66250.html )
I do not find anything about it in any statistical books of me.

to R Core T: mle function in 32bits not respecting the constrain
I have an issue using mle in versions of 32 bits.
I am writing a package which I want to submit to the CRAN.
When doing the check, there is an example that has an error running in the
32 bits version.
The problem comes from the mle function, using it with a lower constrain.
In 64 bits version it works fine but when I put it in the R 32 bits it
fails. (same numbers, all equal!)
The call is:
*mle(minuslogl = p.est,start = beta,method =
"L-BFGS-B",lower=llim*reduction)*
lower = -0.01570427
The optimizer (optim function in 32 bits) display:
