Unreadable labels
Playing around with examples from MASS4, I found a font problem in the mosaicplot in R-2.3.0. It doesn't happen in other plots. Running this example from MASS4, page 326... library(MASS) caith1 <- as.matrix(caith) names(dimnames(caith1)) <- c("eyes", "hair") mosaicplot(caith1, color = TRUE) ...I get an image as attached. The column and row labels are unreadable. It

Standard error of coefficient in linear regression
Hello R users, I have a substantial question about statistics, not about R itself, but I would love to have an answer from an R user, in form of an example in R syntax. I have spent whole Sunday searching in Google and browsing the books. I've been really close to the answer but there are at least three standard errors you can talk about in the linear regression and I'm really confused.

Transforming results of the summary function
Hi all, I have a question about transforming the data from summary function. Let's say I have a data frame like this: > x = data.frame(a = c(rep("lev1", 5), rep("lev2", 5)), b = c(rnorm(5)+2, rnorm(5))) > x a b 1 lev1 1.5964765 2 lev1 2.2945609 3 lev1 3.5285787 4 lev1 1.4439838 5 lev1 2.2948826 6 lev2 1.7063506 7 lev2 -0.4042742 8 lev2

Garbled plot label
Hello, While using the "plot" function against a model with a long formula, I get a garbled label in the bottom of the plot. It looks like there are two lines printed one over another, here's my example: http://pico.magnum2.pl/maciej/NodalInvolvement/MisclassificationRate?action=AttachFile&do=get&target=TwoFactorResiduals.png This was from using

Remove columns from data-frame
Hello, I'm new to the list, hello everybody! :-) I have a question. I looked carefully through the documentation and googled, and found no answer, so I'm posting it here. Let's say I have a data frame with lots of columns (about 300), which are factors. Many columns-factors have only one level, for example all are "Yes" or all are "No". If I try to do a

How to intepret a factor response model?
Hello, I'd like to create a model with a factor-type response variable. This is an example: > mydata <- data.frame(factor_var = as.factor(c(rep('one', 100), rep('two', 100), rep('three', 100))), real_var = c(rnorm(150), rnorm(150) + 5)) > summary(mydata) factor_var real_var one :100 Min. :-2.742877 three:100 1st Qu.:-0.009493 two

Encode wav to uncompressed flac
I thought that an uncompressed FLAC file provides better sound quality than a compressed FLAC file.

Using NFS to extend local email storage
We are running our IMAP mail server on a VPS in the cloud (dovecot+exim+horde webmail), and we are using our on-premises NAS for daily backups through custom rsync scripts (which work well with maildir). There is a lot of storage available on the NAS, while not so much on the VPS. Since, we often get downtime on-premises due to power outages we cannot move the mail server on-premises (though the

I Need to Build a Custom Kernel - missing step
Hi, I was trying to build a custom kernel following the steps defined at https://wiki.centos.org/HowTos/Custom_Kernel. It seems to me that: 1. Step 4 should precede step 2 2. At the beginning of the current step two you should execute: rpmbuild -bp kernel.spec (otherwise no kernel-related directory will exist in `/rpmbuild/BUILD/). -- Pozdrawiam/Regards, Maciej Iwanowski

Encode wav to uncompressed flac
There is no quality difference between FLAC variations - compressed or uncompressed (unless you force a 24-bit audio file into a 16-bit FLAC, but that may not even be possible). The only thing that varies with FLAC is the size of the file. There are many ways to store the same data, some more efficient than others. FLAC ensures that the exact same audio samples will reach your playback

configurable sieve_max_redirects
Witam Sieve implementation in dovecot 1.2 have hard-coded limit for max redirect: SIEVE_DEFAULT_MAX_REDIRECTS 4. I have to rise this to much higher value, e.g. 64. Is there possibility to do this another way than recompiling source? Maybe adding an option to dovecot.conf in plugin section will be a good idea. -- Pozdrowienia Maciej Polewczynski Registered Linux user #117725 OGICOM Sp.

[PATCH] klibc: reproducible builds
From: Maciej ?enczykowski <maze at google.com> This adds a new setting: KBUILD_REPRODUCIBLE If it is non-empty, ar and ranlib will be called in such a way that timestamps do not affect the build output.
