mail_location and storage type
Hi, I was setting up a new system for testing Dovecot 1.0. My old one is using 0.99 and was set up quite a time ago, so I had to consult the documentation. I needed several attempts until it worked and that was because the designated maildir directory /server/mail/jrg/Maildir was completely empty. Upon login the server exited and wrote the following to the log: POP3(jrg): Ambiguous mail location setting, don't know what to do with it: /server/mail/jrg/Maildir (try prefixing it with mbox: or maildir:) POP3(jrg): Failed to create storage with data: /server/mai...

JRG Console Output
All, I had a question about the JGR console and whether or not I can manipulate the location where line wrapping occurs. I have searched 'JGR' in the R listserve archives and attempted to find console manipulation on the JGR website to no avail and could use some direction. TIA, Bret As an example, the below output wraps every 4th value, leaving about 2/3 of the console empty. >

Interesting behavior of lm() with small, problematic data sets
Indeed (version-specific). With R 3.4.1 on linux, I get coefficients and residuals that are numerically exact, F-statistic = NaN, p-value = NA, R-squared = NaN, etc. All of which is what ought to happen, given that the response variable (y) is not actually variable. ---JRG John R.

> I think what you're seeing is > https://en.wikipedia.org/wiki/Loss_of_significance. Almost. All the results in the OP's summary are reflections of finite precision in the analytically exact solution, leading to residuals smaller than the double precision limit. The summary is correctly warning that it's all potentially nonsense, and indeed the only things you can trust are

VAD Questions
...ent API seems to imply that some kind of polling is required to determine the voice/non-voice status. - Does the VAD algorithm implement syllabic/sonorant rate detection, as has been implemented many times in analog circuitry, and is described in this (and other) papers? http://people.csail.mit.edu/jrg/2005/IS05_schutte.pdf - Over what time period is VAD done? Is it done on a frame by frame basis or over some longer period? Thank you, -- Larry Gadallah, VE6VQ/W7 lgadallah AT gmail DOT com PGP Sig: 616D 4E52 CF1F 3FEC FFFB F11B 7DB9 C79A EA7E B25B

ss's are incorrect from aov with multiple factors
Hi, I have been trying to work with error terms given back from aov to make confidence intervals. However, the numbers seem to be incorrect. If there is more than one term in the ANOVA then the error terms can be inflated by the number of factors in the extra terms. The F's are correct so it is right back to the SS. I was wondering if this is standard practice for stats programs or

invert y-axis in barplot
Hi! This is probably a very trivial question. Is there an easy way to invert the y-axis (low values on top) when using the function barplot()? Thanks, Jörg [[alternative HTML version deleted]]

pure statistical question
Dear all, This is a pure statistical question, not necessarly related to R. I could not find it in literature. Suppose I'm intersted in a parameter rho, say, equal to: r=beta1/beta2, where beta1 and beta2 come from a linear model y=beta0+beta1X1+beta2X2+.... Fitting the model I can get the (biased) estimate of r=b1/b2, where b1 and b2 are the estimates in the regression model; I can get the

reference for round
The help for the round function states: round rounds the values in its first argument to the specified number of decimal places (default 0). Note that for rounding off a 5, the IEEE standard is used, ``go to the even digit''. Therefore round(0.5) is 0 and round(-1.5) is -2. Could someone provide a reference for this standard? Thanks, Anne ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Anne E.

Error with 'var' in JGR
R-Users, I had a strange occurrence this AM I could use some help with. 'var' seems to have ceased to work for me when I used JGR 1.3 interface. So, I ran a quick test (following pg 57 of Dalgaard) in both the basic RGui and JGR interface (see below). I have re-installed R 2.2.1 and JGR 1.3 but had no luck so far figuring this out? Anyone have a suggestion? Or did I just make a

Hypothesis test
Dear colleague: Actually that is what is done. When using the z-test between proportions in two different groups, or using chi-squared to test the null hypothesis of equal proportions of two or more groups, the null hypothesis is that H0: p1=p2=p3.....=p where this p is the pooled proportion, the proportion in the summed groups = n1+n2+n3+..../N1+N2+N3.... in the z-test between two

strange QQ-Plot
Hi, i am working on a data set with EDA. That includes QQ-Plots of residuals vs expected normal distribution. What puzzles me is that the range of ordinate and abscissae is so different: while the theoretical quantiles range from [-2, 2] the sample quantiles on the ordinate do extent from [-20, 50]. Quite obviously some kind of transformation is done. Although i intensively RTFM i could not

calculating std err (SEM)?
Is there a "canned" function in R for finding the standard error of the mean? I have tried > sem <- function(x) c(mean =mean(x), + SEM = stdev(x)/sqrt(length(x))) > sem(pnet.lai) Error in sem(pnet.lai) : couldn't find function "stdev" It looks like there is no stdev function in R Thanks, Kirk Kirk R.

lme newbie question
Hi I try to implement a simple 2-factorial repeated-measure anova in the lme framework and would be grateful for a short feedback -my dependent var is a reaction-time (rt), -as dependent var I have -the age-group (0/1) the subject belongs to (so this is a between-subject factor), and -two WITHIN experimental conditions, one (angle) having 5, the other 3 (hands) factor-levels;

- round() strange behaviour
Hi, I am getting some strange results using round - it seems that it depends if the number before the decimal point is odd or even .... For example: > round(1.5)[1] 2> round(2.5)[1] 2 While i would expect that round(2.5) be 3 and not 2. Do you have any explanation for that? I really appreciate your input, Monica

k3b -> cddb doesn't work
Copying a CD with k3b is no problem, except I want to include on my copy the cbbd data (from freedb.org). I've configured k3b's cddb section according to instructions at <http://www.freedb.org/en/faq.3.html#15> and read every article google could find about "k3b cddb freedb.org config", but still k3b can't manage it. Grip handles getting the cddb data just fine.
