solnp inconsistent error messages
Dear all,
I am tryng to solve a nonlinear optimization probel using the solnp function.
I have different datasets. For the smaller I get full solutions, for

Rsolnp package: warning messages
Dear,
I am using the solnp command (package Rsolnp) for a problem with
equality and inequality constraints.
I am not getting convergence for my problem but apart that I get 1
warning per iteration saying: ?In cbind(temp, funv) : number of rows
of result is not a multiple of vector length (arg 1)?.
I checked for equality and inequality functions and they seem fine to
me. Where this

trouble with installing pbatR
Hello folks,
I am having a problem installing pbatR package. (My R version is 2.8.1.)
As I execute a command
> install.packages(lib='/usr/local/apps/R-2.8.1/lib64/R/library', "pbatR")
it detects lack of rootSolve package and attempts to install it. But
cannot seem to compile it, and the rest is aborted.
Any hint as to what I can do?
Thank you in advance for your

Wish: keep names in mapply() result
Hello!
I have noticed that mapply() drops names in R 2.3.1 as well as in
r-devel. Here is a simple example:
l <- list(a=1, b=2)
k <- list(1)
mapply(FUN="+", l, k)
[1] 2 3
mapply(FUN="+", l, k, SIMPLIFY=FALSE)

Rsolnp examples
I'm interested in the Rsolnp package. For their primary function
"solnp", one example is given, and there is a reference to "unit
tests". Anyone know where these can be found? Also, Rsolnp is
used in a few other packages (e.g., depmixS4), but I cannot seem
to find source illustrating its call sequence, and the precise
definition of the functions passed.
Can anyone help?

How to nicely display R code with the LaTeX package 'listings'?
Dear expeRts,
What's a 'good' (nice-looking, easy-to-read) setup for the LaTeX package

The two versions below are partly inspired by the settings of the package

Signed or unsigned EQ/NEQ
Hello,
In one of the loop transformations I am developing, I need to convert eq
and neq loop latch condition into less than or greater than depending on
the control flow.
The problem is that CmpInst::ICMP_EQ and CmpInst::ICMP_NE are neither
signed nor unsigned in LLVM. Also, I did not find a way to find out if the
integer operands of the CmpInst are signed or unsigned. Apparently, LLVM

Nonlinear programming problem
Hello useRs,
I'm using the command "solnp" in package "Rsolnp" to solve a general nonlinear programming problem. But I got an error that " the leading minor of order 15 is not positive definite
". Can anybody tell what may cause this error? Does it have something to do with the starting values?
Thanks a lot!!!

RExcel issues
Hi -
For a while I've used RExcel without problems to run a repeating portfolio optimization problem where I solve for a portfolio allocation targeting a particular risk, then solve for a different risk, etc. I call the commands with (e.g.) rinterface.Rrun "(R command)"
Recently that macro started blowing up, returning #RErrors, and when I try to trace the error I find that it is

Oblivion inversed sound
The problem is the sound output is inversed. What should be heard on the right is heard on the left side and vice versa.
So ... if a guard is on your left and he says something you hear him from you right side... This applies to all sounds not just chatter.. bonfires, horse, etc...
Is there any way to fix this?
Used wine 1.3.0 and currently using wine 1.3.1. Running Ubuntu 10.04 32bit. Oblivion

Possible bug in the Rd parser?
Dear list,
I got an automatic email complaining than some of my packages didn't
pass 'R CMD check' for R-2.10.0 alpha anymore. Both of them make use of
the "cases" LaTeX environment.
Inspecting the log outputs I got:
LaTeX errors when creating PDF version.
This typically indicates Rd problems.

[PATCH] mllib: Getopt: fix integer parsing
Since we are using gnulib already, make use of xstrtol to parse the
integer arguments to avoid extra suffixes, etc.
Fixes commit 0f7bf8f714898c606e5d5015fff5b7803dcd1aee.

summation coding
I would like to code the following in R: a1(b1+b2+b3) + a2(b1+b3+b4) +
a3(b1+b2+b4) + a4(b1+b2+b3)
or in summation notation: sum_{i=1, j\neq i}^{4} a_i * b_i
I realise this is the same as: sum_{i=1, j=1}^{4} a_i * b_i - sum_{i=j} a_i
* b_i
would appreciate some help.
Thank you.
