Hello, I've a test system with postfix (SMTP), dovecot (IMAP only) and covecot-LDA (MDA) under FreeBSD-6.1. Currently everything works fine. But I wasn't able to install dovecot-sieve from the CVS. Does anyone has a small documentation howto install dovecot-sieve on FreeBSD. Thanks. -- Der GMX SmartSurfer hilft bis zu 70% Ihrer Onlinekosten zu sparen! Ideal f?r Modem und ISDN:

Dear folks-- The function below is a snippet of a larger function that is not doing what it is supposed to do, and I do not understand its behavior. The larger function is supposed to produce an array containing the results of a user-specified function applied to groups of data defined by the intersection of one or more factors, and return them in an array with a dimension for each factor and a

Hello ! I have a quick question about loops. For example, I have a 1 * 1 square and its inscribed circle tangent i, whose radius, of course, is also 1. The loop here is as the following: generate n points, say 5, in the square randomly repeatedly until we have five in total in the circle, then we stop, otherwise we continue. I do not know how ! Help me Please ~ Thank you very much for

I have a dataset of 10000 records which I want to use to compare two prediction models. I split the records into test dataset (size = ntest) and training dataset (size = ntrain). Then I run the two models. Now I want to shuffle the data and rerun the models. I want many shuffles. I know that the following command sample ((1:10000), ntrain) can pick ntrain numbers from 1 to 10000. Then I just

Dear R-helpers, I would appreicate if someone can help me on the transfer parameter in ARIMAX and also see what I am doing is correct.

Hello everybody, I'm testing the randomForest package in order to do some simulations and I get some trouble with the prediction of new values. The random forest computation is fine but each time I try to predict values with the newly created object, I get an error message. I thought I was because NA values in the dataframe, but I cleaned them and still got the same error. What am I

Hi, I am starting to learn using libvirt with kvm on CentOS 6. Just used this command to start a guest: virt-install -ntest -r1024 --vcpus=1 -c/var/lib/libvirt/images/CentOS-6.0-x86_64-netinstall.iso --os-type=linux --os-variant=rhel6 --disk vol=kvmguests/test --vnc -v --virt-type=kvm --check-cpu --prompt --arch=x86_64 Then I found out that I misconfigured vnc. And I do not know how to

Thanks. Will try it. Have not tried it but I think the following may work: out$results<-NULL out$results$ei<-ap out$results$vi<-vap All I need is printing by returning out (unless I turn it off). And, retrieve ap and vap as needed as shown above. Guess I need to read more about invisible. On 8/11/2024 10:09 PM, Rui Barradas wrote: > ?s 09:51 de 11/08/2024, Steven Yen escreveu:

Hello, I am trying to call sendmail from within R via system(). As sendmail reads from STDIN, I need to pass a multiline input as an argument. E.g. (not working): system('sendmail -f xxx at swing.be -t yyy at swing.be\ntest\n.\n') I tried a lot of ways to type the EOL characters, but cannot get them work the right way. This leads to several problems. For instance, R waits for me to

Hello, I've written a simple (although probably overly roundabout) function to test whether two regression slope coefficients from two linear models on independent data sets are significantly different. I'm a bit concerned, because when I test it on simulated data with different sample sizes and variances, the function seems to be extremely sensitive both of these. I am wondering if

Hello, I am using a dict proxy for my sieve extdata plugin to access some fields from an SQLite database (autoreply text and other database-configured items). All tests are performed against version 2.2.25. $ dovecot --version 2.2.25 (7be1766) My configuration looks like: dict { sieve = sqlite:/etc/dovecot/pigeonhole-sieve.dict } [...] sieve_extdata_dict_uri = proxy::sieve I
