Hi ! I wonder if the R application is capable of utilizing more than one CPU. I need to know since we run it on a SunFire 3800 with 8 750 USIII cpu:s and on a E420R with 4 USII cpu:s and we don't feel like we get the performance we could expect. I've seen some old discussions claiming that it isn't. With kind regards Lennart Araskoug

Hi All, We have been running samba-1.9.18p10 beautifully for the past year or so. Finally decided to upgrade to samba-2.0.6 and am having no luck. We are using security=server such that the users are using their NT login/password to authenticate. When I test the 2.0.6 installation with smbclient, I get the "protocol negotiation failure" message. Does anyone know what this means? I

I have been lurking in this list a while and searching in the archives to find out how one learns to write fast R code. One solution seems to be to write part of the code not in R but in C. However after finding a benchmark article (http://www.sciviews.org/other/benchmark.htm) I have been more interested in making the R code itself more efficient. I would like to find more info about this. I have

We are trying to compile and run the ttest.c example that comes with R (in C:\Program Files\R\rw1081\src\library\windlgs\src\ttest.c). After compiling it with MS Visual C++ we load the DLL with dyn.load. So far it seems good, but when we try to call it from R (after running C:\Program Files\R\rw1081\src\library\windlgs\R\windlgs.R) R crashes. We have tried changing the exports from DLL but have

Hi, I am writing C++ functions that are to be called via .Call() interface. I'd been using error() (from R.h) to return to R if there is an error, but then I realized that this might be not safe as supposedly error() doesn't throw an exception and therefore some destructors do not get called and some memory may leak. Here is a simple example extern "C" void foo() { string

Hi all, Five minutes ago I heard a rumor that Lennart Poettering has rewritten rsync. My top urgency is to download the latest numbered version of rsync untouched by Lennart Poettering: I'll find out if the rumor is true or false later. I've downloaded rsync rsync-3.1.3.tar.gz and rsync-patches-3.1.3.tar.gz from https://download.samba.org/pub/rsync/ . Is the source code in both those

Hello, I am currently trying to connect my Dovecot mail server to Microsoft's Azure-AD and use it as password and user database. I am using version 2.3.7.1. Using the Azure-AD as passdb already works. In this context I noticed that the scope implementation is not yet merged. Since I haven't found any hints for an OAuth2 userdb implementation yet, I wanted to ask if there are any plans

Hi, Is there some documentation about what has not been implemented yet? I'm trying to use vectors and I just run into one thing after another that seem to be missing. (I.e., fcmp on vectors doesn't work; trying to do the same thing with expanded instructions doesn't work; select on a vector doesn't work) -- Lennart

I've started adding notes to docs/LangRef.html Historically this document has been used to describe just the LLVM IR, and not what specific consumers of it do or don't support, but codegen is a very

Dear List I would like to ask you something concenting a better print of the R output: I have a bit data frame which has the following structure: CFISCALE RAGSOCB ANNO VAR1 VAR2......... 9853312 astra 2005 6 45 9853312 astra 2006 78 45

Currently as the first column in a data frame I have string values in the format xx_yy - I want to create a new column with just the substring xx (for each row in turn). Three possible ways to do this might be (1) split the string by '_' using strsplit and paste the first of the resulting variables into a new column, but I have been unable to do this for each row of my data frame in turn

I feel like I'm going totally crazy. Is it just me, or have embedded From_ lines really been breaking mbox messages since (at least) dovecot 1.0? I found a whole lot of broken messages in an old mailbox of mine and when I looked closer at it, it seemed like Dovecot was ignoring the Content-Length header and truncating the messages at the first embedded From_ line instead. Figuring

I wonder if there is a package that will estimate a Zero Inflated Poisson Model (ZIP), and also if there is a package that will estimate what is called the Tobit model: that is a combination of censored and observed values in the same sample.
