building an R package : where and how should my fortran library be loaded ?
Hi , I'm currently trying to make available a few fortran subroutines and R functions (which make interface to these subroutines), as an R package. I'm doing it under linux with R 1.9.0 (but hope to do it for windows too). I have trouble for loading my fortran code. Here are the steps involved : 1) In R: # Create tree for package

calling fortran functions CHOL and DPOTRF form Fortran
Hi all, I'm working out some Fortran code for which I want to compute the Choleski decomposition of a covariance matrix in Fortran. I tried to do it by two methods : 1) Calling the lapack function DPOTRF. I can see the source code and check that my call is correct, but it does not compile with: system("R CMD SHLIB ~/main.f") dyn.load("~/main.so") I get: Error in

building a package under windows
Hi, I have a package of my own which seems to work fine under linux. I want to make a compiled version for windows. (I work with windows 2000 and R 2.0) I have followed the steps described in the file readme.packages (in the top-level directory of the binary installation) and I had a trouble at this step (which aim is not documented): C:\Program Files\R\rw2000\src\gnuwin32>make libR.a

Folding Samba into existing PAM_LDAP?
I have the same question, I've got an existing openldap sever running with posixAccount users for linux pam/nss auth working OK . How can I enter smbpasswd users information to the existing Ldap database (just add the sambaSamAccount information needed for a PDC base on Ldap auth) !? Idealx scripts creates a whole dedicated Ldap database :-( .

smb + nfs lock problem
Hello, whenever I try to copy a new file from windowsXP (2K also) to a samba share which is NFS mounted on the samba server, I get an error on the client: "impossible to copy file.txt: the process cannot access the file because an other process has locked a part of it" (my english translation of the french message I have !) It worked fine before (3weeks ago) and I think that problem

Re: FLAC on Pocket PC

Just copy the flac-1.1.0 directory into flactest (so that the path flac-1.1.0\include and flac-1.1.0\src exists in flactest). The project should then compile as is. All the code is in flactest.cpp. It's pretty basic. You'll have to

Calling C from Fortran
I would like to call C routines from Fortran under linux as suggested in section 5.6 of the "Writing R extensions" documentation. I'm familiar with Fortran but not with C. I understand the example provided in Fortran: subroutine testit() double precision normrnd, x call rndstart() x = normrnd() call dblepr("X was", 5, x, 1) call rndend() end but I don't understand

R binomial RNG stuck at 1 via Fortran call

FLAC on Pocket PC
Hi, I'm trying to use FLAC (v1.1.0) on a Pocket PC (Toshiba e740). It compiles fine without any warning. When I try to compresse 16bits waves, everything is fine. When I try to compress 8bits waves, I get a audio mismatch error (FLAC__STREAM_ENCODER_VERIFY_MISMATCH_IN_AUDIO_DATA). Does anyone have had this problem? I can send the project if someone can look at it. Thanks, Jehan

Deferred emails on alias emails
Hi, I am currently making a fresh install of email server. I am having some issue with dovecot-antispam (cf. other emails), and noticed that I was having issues on aliases, which apparently where not forwarded to the actual SMTP server after passing through dspam. Still don't figure why but temporarily disable the dspam filter, which anyway is not useful in the current state of this

Hi all,
Hi all, as I told earlier, I am installing an email server with postfix/dovecot/dspam (for now that's all, though some programs may come later). For now, what works good enough is that I receive mails and spams are tagged. Dovecot version 1.1.7-r1 compiled from the gentoo depository with debug. The path of a mail is 1/ to be passed to dspam by postfix as a virtual transport with this in

Model II regression
Hello, I am using function lmodel2 to calculate RMA regression between life-history traits in ladybirds beetles. It works well but I am not able to plot an RMA regression line on the scatterplot of my data. I am of course unable to plot the confidence intervals. For ordinary least square regression abline(lm(x~y))works well but for RMA regression, abline(lmodel2(x~y))does not do it. If somebody

How can rsync detect renamed files ? If it is possible.
Hi, I read that rsync can find files that we renamed. So, I would like to know how it can do that, if it's really possible ? I think there is a link with the file-list but I don't understand how it can detect that a file named 'test' is the same than the file renamed 'test_bis' for example. I didn't test it so I don't know if my question is correct. Micka?l

How rsync works
Hi, I'm translating the document How rsync works to understand exactly how rsync works when it finds modified files. I'm translating "the sender" and I notice a strange fact. I would like to take an example where a byte is missing in a file. In facts : The generator has created a cheksum for the first file to the sender. Then, a checksum is created for the local file beginning
