grep function with patterns list...
Dear R-users,
is there a way to pass a list of patterns to the grep function? I
vaguely remember something with %in% operator...
Thanks,
St?phane.

Multiple stacked barplots on the same graph?
Dear R-Users,
I would like to know whether it is possible to draw several
stacked barplots (i.e. side by side on the same sheet)...
my data look like :
Cond1 Cond1' Cond2 Cond2'
Compartment 1 11,81 2,05 12,49 0,70
Compartment 2 10,51 1,98 13,56 0,85

possible bug in ggplot2 v0.5.2???
Dear R-Users,
I recently gave a try to the nice package ggplot2. Everything went
well until I tried to add a smoother (using lm method for instance).
On the graphic device the regression line is displayed but not confidence
intervals as it should be (at least on ggplot website). I tried to do
the job on
both MS winXP and Linux i586: same result. Did anyone encountered this
problem? Did I miss

Dear Kornad,
I think I have started to understand what you try to achieve. The problem is to fit a NLE and compute the parameters of the NL-Eq. I have included the R Help-list back in the loop, as I am not an expert in optimization.

Interaction term in multiple regression
Hello All, Thank you for taking my question. I am looking for
information on how R handles interaction terms in a multiple regression
using the ?lm? command. I originally noticed something was unusual
when my R output did not match the output from JMP for an identical
test run previously. Both programs give identical results for the main
test and if the models do not contain the interaction

extension to nlme self start SSmicmen?
Dear list,
Has anyone created a version of SSmicmen that allows testing for group
differences? The basic Michaelis-Menten equation is:
(Bmax * X) / (Kd + X).
The nlme package allows modeling of random effects for Bmax and Kd as
needed, but I curious how I can build in group differences? I have

mutual information for two time series
Hi I hope this is going to the right place. I am trying to write a program
which uses KernSmooth library to estimate mutual information between two
time series at various different lags. At the moment it’s producing negative
values, which is supposed to be impossible (something is fishy). I am
summing across one row of the matrix to get p(value is in bin x) and summing
across the columns to get

[LLVMdev] Using LLVM to convert a language to another language
Hi,
Sorry for my newbies questions... but here it is...
My goal is to have a "shading language", it is very similar to the "C" language but with special tokens.
I have a parser and a lexer done with Lex/bison, once I have lexed/parsed my "shading language" I must create 3 new "source code" in OpenCL.
It mean that by example for the following :

Calling a LAPACK subroutine from R
Followup:
I have checked my package nleqslv which uses dgemv only from Fortran, on Kubuntu 18.04 with the development version of R.
No errors or problems.

WinDbg?
Hello,
I have been struggling with WinDbg/Kd for the last week, but to no avail... So I finally decided to ask here.
Basically, I am using a Windows XP virtual machine (thanks to VMWare6) and wanted to do some kernel debugging using Windbg. So, I did configure everything from the virtual machine side (using this guide: http://silverstr.ufies.org/lotr0/windbg-vmware.html), and then tried my hands

Fw: Calling a LAPACK subroutine from R
Berend,
I do not think this works with gfortran 7+. I am calling the BLAS
subroutine dgemv from Fortran code in my package eha, and the check

Yes, I know how to do that, but I find it somewhat bizarre that it is
impossible to call a Fortran subroutine from Fortran. And rewriting
'dgemv' was simple:

R crash with ATLAS precompiled Rblas.dll on Windows XP Core2 Duo
I noticed a problem using R 2.7.1 on Windows XP SP2 with the precompiled

predict.loess() segfaults for large n?
Hi,
I am segfaulting when using predict.loess() (checked with r62092).
I've traced the source with the help of valgrind (output pasted
below) and it appears that this is due to int overflow when
allocating an int work array in loess_workspace():
liv = 50 + ((int)pow((double)2, (double)D) + 4) * nvmax + 2 * N;
where liv is an (global) int. For D=1 (one x variable), this

one-site competition data // curve fitting
Hello everyone,
I have biological data from a competition experiment where a free ligand is titrated against the binding of a protein.
Now, I would like to fit a standard on-site binding curve to this data in order to obtain the IC50 and Kd values.
Unfortunately I have not been able to find a package/function which allows such a fitting and calculates the results.
