Hello, I use t.test for normal distributed and wilcox.test for non-normal distributed samples. It is easy to write a function for t.test that calculates the effect size, because all parts of the formula are available from the t.test result: r = sqrt(t*t / (t*t + df)) However, for Wilcoxon tests, the formula for effect sizes is: r = Z / sqrt(N) I wonder how I can calculate the Z-score in R for

Full_Name: Stefan Raberger Version: 2.8.1 OS: Windows XP Submission from: (NULL) (213.185.163.242) Hi there, I recently noticed some strange behaviour of the command "type.convert", depending on the startup mode used. But there also seems to be different behaviour on different PCs (all running the same OS and the same version of R). On PC1: When I start R in SDI mode (RGui --no-save

Hello, I'm trying to plot a fitted lm() line on a plot when the one explanatory variable is log transformed and log="x". I get different lines using abline and predict.lm(). #Example x <- 1:100 y <- rnorm(100) plot(y ~ x, log="x") abline(lm(y ~ log(x))) lines(x, predict(lm(y ~ log(x))), lwd=2) I'm sure I'm missing something but could someone tell me which

Hi, I just started with R and I found that there are many options to rearrange the data to do mixed models. I want to use the reshape function. I have 2 between subject variables and one within. I was able to change the data structure but still - the result of the aov functions are calculating everything as a within subject. the table looks like this: SerialNo breed treatment distance_1

Dear all, Is there a less cumbersome way to rename a column by name (as opposed to index) than -- names( X)[ names[ X] == "bob"]<-"sue" ? A semi-related question: how does one get the index of a column by name, something along the lines of col.index( X, "sue") ?

Hi I had observed the following problem in R (also C, Matlab, and Python). sprintf('%1.2g\n', 3.15) give 3.1 instead of 3.2 whereas an input of 3.75 gives 3.8. Java's System.out.printf is ok though. > round(3.75,1) [1] 3.8 > round(3.15,1) [1] 3.1 Similar outcome with sprintf in R. However, the right answer should be 3.2 Regards Teckpor [[alternative HTML version

Hi, The following function works, but is there a neater way to write it? f = function(x,...) { # return a character vector of the arguments passed in after 'x' gsub(" ","",unlist(strsplit(deparse(substitute(list(...))),"[(,)]")))[-1] } > f(x,a,b,c*d) [1] "a" "b" "c*d" > Thanks. [[alternative HTML
