Problem with ddply in the plyr-package: surprising output of a date-column
Hi Together, I have a problem with the plyr package - more precisely with the ddply function - and would be very grateful for any help. I hope the example here is precise enough for someone to identify the problem. Basically, in this step I want to identify observations that are identical in terms of certain identifiers (ID1, ID2, ID3) and just want to save those observations (in this step,

Matching Problem: Want to match to data.frame with inexact matching identifier (one identifier has to be in the range of the other).
Hello R-Community, I have the following matching problem: I have two data.frames, one with an observation every month (per company ID), and one with an observation every quarter (per company ID; note that quarter means fiscal quarter; therefore 1Q = Jan, Feb, Mar is not necessarily correct and also, a fiscal quarter is not necessarily 3 month long). For every month and company, I want to get the

Hallo, i tried to backup samba4 by using the samba_backup script. I removed ?>/dev/null 2>&1?-Pipe from the tar-commands. Tar could not archive the temporary msg-files, because they where open.

Change font size in Windows
My day for dumb questions. How do I increase the type size in the Rgui console in Windows? (R-2.13.0, Windows 7) It looked to me that I just needed to change the font spec in Rconsole but that does not seem to be working. The R FAQ for Windows has a reference in Q3.4 to changing fonts, (Q5.2), but I don't see anything relevant there. Rconsole originally was: font = TT Courier New points =

Problem implementing 'waldtest' when using 'mlogit' package
Hi all, I have been working through the examples in one of the vignettes associated with the 'mlogit' package, 'Kenneth Train's exercises using the mlogit package for R.'

Specifically, I have run the following command, where mc and mi2 are

SSL encryption with icecast2
Hi there, is it possible to use such encryption like SSL/TLS for authenticating users on a mountpoint? I can't find somethin like that in the docmentation and it would be nice to have such a mechanism like that, because all passwords will be transmitted in PLAIN text. This is not very secure, because anyone can see the usernames and passwords in his sniffer program. Would be pleased if

dovecot & vpopmail
Hi! Authentication works, but default_mail_env = maildir:/usr/local/vpopmail/domains/%d/%n/Maildir/ is translated by the "imap"-process to /usr/local/vpopmail/domains//testerhorst/Maildir/ although I succesfully log in as testerhorst at elektropost.org. Is there a manual how to use dovecot with vpopmail? We have here: FreeBSD 4.9-STABLE, vpopmail-5.4.0 and dovecot-0.99.10.4_2.

regexp problem
Hi I have a question concerning regexp - I want to select with grep all character strings which contain the numbers 11:20 (code below). At the moment I am using [], but that obviously does not work, as it matches each element in the []. Is there a way to specify that the regexp should match 11, but not 1? Here is the code code: x <- paste("suff", 1:40, "pref",

Full_Name: Cornell Gonschior Version: 2.10.0 OS: Linux Submission from: (NULL) (212.201.28.40) Hi, in the introduction to R, you can find the following sentence in the par() chapter: "Use tck=0.01 and mgp=c(1,-1.5,0) for internal tick marks."

Dear R-help-list, I have a problem in which the explanatory variables are categorical, the response variable is a proportion, and experiment contains technical replicates (pseudoreplicates) as well as biological replicated. I am new to both generalized linear models and mixed- effects models and would greatly appreciate the advice of experienced analysts in this matter. I analyzed the
