Group permissions issue migrating from 2.2.8a to 3.0.23a
Hi,
I have a share that worked fine in samba 2.2.8a, users were able to read and
write to the share, and edit files. After migrating to 3.0.23a, users are no
longer able to edit existing files.
Samba 2.2.8a config:

comment = SALES
path = /home/netshare/sales
read list = @purch, @shipping
write list = @adm, @mgt, @sales, @vag, +hap

LAPACK Headers
Hey Everyone,
I'm running R 2.4.0 on Debian etch 4.0, and I'm trying to call some
LAPACK functions from the C code in my package. Actually, to be
honest I'm not really having trouble using commands such as La_dgesv
from within my C code, but I do get warning when compiling the package
saying:
***.c: In function '***':
***.c:37: warning: implicit declaration of function

R Lapack – why a subset?
Peter,
Is there not already a significant maintenance burden from cherry-picking routines? From my own experience (https://bugs.r-project.org/bugzilla/show_bug.cgi?id=16482 <https://bugs.r-project.org/bugzilla/show_bug.cgi?id=16482>) this is a painful process. And while users may not call these complex routines directly, R is often used as a front-end for libraries that do, so

LAPACK lib problem, lme4, lastest R, Linux
I just dumped Vista off a laptop and installed Ubuntu 10.10 (latest
release) as the single operating system. I did all of the updates and
then installed emacs and ess. Next I installed R by following the the
usual instructions on the CRAN site. At this point all is working I am
now in the process of installing the packages that I normally have
installed. I am having a problem with the LAPACK

LAPACK libraries improperly linked
I am not sure if this is an R development problem or not. I am starting
with completely clean OS and and installing the latest version of R
without trying to anything special but I am having trouble with the
LAPACK library linking when I try to build packages that require them.
I thought perhaps my problem may be if interest here.

Using R's LAPACK & Related files in Visual C++
I am a relative newcomer to both the R and C/C++
software worlds -- I'm taking a C Programming class
currently. I noticed the other day that the
C:\Program Files\R1_8_1\src\include\R_ext
directory on my WinXP box has the header files
BLAS.h
Lapack.h
Linpack.h
RLapack.h
I am interested in (perhaps) using one or more of
these
header files in a straight C program I'm working on in

Using functions in LAPACK in a C program
Hi,
I wonder where I can find an example of using a function in LAPACK library in a user's own C code. I wrote a C program which will be compiled and linked to produce a DLL file and then loaded into R. I hope to use a function from LAPACK library, for example, dgesdd, in the program. Following R manual, I call the function by F77_CALL(dgesdd) in the program. The program can be compiled

R Lapack – why a subset?
Hi,
Why doesn't R include a full Lapack but only a subset?
My cda package (now archived) relying on RcppArmadillo has broken multiple
times on CRAN over the past few years following updates in the underlying
Armadillo library, Every time it follows the same pattern: Armadillo adds a
function to solve a specialised linear system more efficiently, and the
corresponding Lapack routine is not

Problems Building R on AIX 5.2.0.0 (Update)
Hi,
My previous message is appended: I'm still struggling with building on AIX. I
updated my config.site to follow the suggestions from R-admin:
MAIN_LDFLAGS=-Wl,brtl
SHLIB_LDFLAGS=-Wl,-G
This led to an error during configure:
checking whether mixed C/Fortran code can be run... configure: WARNING: cannot

ubuntu problem with 'r-cran-robustbase' [FWD Agustin Lobo]
Agustin, posted on R-help.
I think the problem is one of the debian/ubuntu package
'r-cran-robustbase' and its setup or (missing?) dependencies.
I can confirm Agustin's problem, working on Ubuntu 8.04.2
(8.04 is a "LTS" = long time support version).
apt-get install r-cran-robustbase
works fine, but when trying to load the package,

LAPACK.dll and Excel with R 2.7.0
Hello,
I was building a R addin for Excel. I was able to build R.dll, export to
Rdll.lib and wrap it in a Excel addin (.xll) format. Most basic
functions work fine within Excel except functions that use LAPACK, e.g.
eigen, solve etc. But if you use solve(..., LINPACK = T). That's fine.
So apparently the problem is with loading the shared library

Problems Building Ron AIX 5.2.0.0 (Solved)
Happily I got this to work, largely by trial-and-error. In hopes that this will
help somebody else, my config.site ended up being:
OBJECT_MODE=64
R_PAPERSIZE=letter
CC=/usr/local/bin/gcc
MAIN_LDFLAGS=-Wl,-brtl
SHLIB_LDFLAGS=-Wl,-G
Which is virtually identical to that recommended in R-admin: one of my problems
was using "-W1,brtl" rather than "-W1,-brtl". This was R 2.0.1
