Effect Size Formaula and Calulations in R
Hello, I would like to find out how to use R to compute the effect size of two samples for a two sample t test. Is there a formula for the fisher's exact test? Any R code and/or formula would be greatly appreciated. Thanks, Jim [[alternative HTML version deleted]]

On the calulation of crossed differences
Dear Contributors, I am back asking for help concerning the same type of dataset I was asking before, in a previous help request. I needed to sum data over subsample of three time series each of them made of 100 observations. The solution proposed were various, among which: db<-p dim( db ) <- c(25,4,3) db2 <- apply(db, c(2,3), sum) db3 <- t(apply(db2, 1, function(poff)

Double quota calulation when special folder is present
Hello, we're operating dovecot on a small server. Some years ago, we migrated from courier IMAP to dovecot. Therefore, we defined our default Namespace "inbox" with prefix "INBOX." to have this compatible. I found this in some migration docs those days. Generally, everything worked as expected. Our only namespace is configured like this: namespace inbox { separator = .

normalizing data sets
Hi, Can someone tell me how to normalize a data set so that the mean of the set is 0 and the variance is 1. As I understand, when you calculate the principle components of a data set through correlation as < princomp( dataset, cor=T ) > then a similar calculation is performed. I would like to know how I can perform such a calulation directly. Any help would be greatly appreciated. Many

Statistical power of correlations.
My apologies for the statistical naivete of my question but... Is there an established method or calulating the statistical power of a correlation test? And if so is there a method in R for it? Thank you, Collin Lynch.

Putting obejct into Graph title
Hello all - If I want to put mean value of a matrix into the title or subtitle of a graph, how would I do this? For example, in a set of commands like below, > m.mean<-mean(m) > gplot (m, thresh=m.mean) > title (main="A2. Block Density of Matrix m\nplotted based on MDS", + sub="lines below mean density (**0.435**) suppressed") I want to ask [R] to put the

calculate age based on DoB
Hi, I wrote a little helper that calulates someone''s age based on his/her date of birth. def age(dob) diff = Date.today - dob age = (diff / 365.25).floor age.to_s end It works fine, but it''s not completely accurate as it just takes the average days in a year. It should be able to calculate this more accurately, right? I can''t work it out

[BUG?] Double quota calulation when special folder is present
Just hoping to get some dev eyes on this. I'm incredibly reluctant to throw the word 'bug' around (since 99 times out of 100, it's not -- it's almost always the config), but I can't think of any way that this could be a config issue, esp when the pre-2.2.34 version works as expected. I noticed during troubleshooting that dovecot errors out if I try to create a subfolder

KLdiv produces NA. Why?
I am trying to calculate a Kullback-Leibler divergence from two vectors with integers but get NA as a result when trying to calulate the measure.

Integrate and subdivisions limit
Dear all, I have some issues with integrate in R thus I would like to request your help. I am trying to calculate the integral of f(x)*g(x). The f(x) is a step function while g(x) is a polynomial. If f(x) (step function) changes its value only few times (5 or 6 'steps') everything is calulated ok(verified results in scrap paper) but if f(x) takes like 800 different values I receive the

numerics from a factor
...ago some test cases that broke survfit were presented to me. The heart of the problem was numbers that were almost identical, where table(x) and unique(x) gave different counts of distinct values. The solution was to use "ftime <- factor(time)" at the top of the code, and do all the calulations using the integer levels of the factor as the unique time points. At the very end the numeric component "time" of the result is created using as.numeric(levels(ftime)). It's this last line that breaks. I could set the OutDec option within survfit and reset when I leave using on.e...

Get window textures even when they're transformed.
If I wobble a window and quickly initiate switcher or cube, this can cause weird artifacts. I had a look at Beryl's switcher.c In switchPaintThumb they use this: static void switchPaintThumb(...) { DrawWindowGeometryProc oldDrawWindowGeometry; AddWindowGeometryProc oldAddWindowGeometry; WindowPaintAttrib sAttrib = *attrib; int wx, wy; float width, height; CompIcon *icon = NULL; /*

Markov Model problem
First, I don't have the correct lingo for this topic, so I can't really find a solution for my problem. And maybe I formulate it incorrectly, so bear with me. How would I calculate a 'constant transition matrix' if I know a given value at a given time? Let's say I know that my value is 54,0 at t=12. How do I get the initial chain value? t markov.growth 00 00.0 01 06.3
