Dear all, I have a question about the 'sdev' value returned by the princomp function (which does principal components analysis). On the help page for princomp it says 'sdev' is 'the standard deviations of the principal components'. However, when I calculate the principal components for the USArrests data set, I don't find this to be the case: Here is how I

Hello, I am wondering whether there is a way to test whether two non-independent correlation coefficients are significantly different, in R? I have an experimentally measure variable Y, and two different variables X1, and X2, which are predictions of Y that were predicted using two different computational models. I would like to see whether the correlation of Y and X1, and Y and X2 is

Hello, I'm a newcomer to R so please forgive me if this is a silly question. It's that I have a linear regression: fm <- lm (x ~ y) and I want to test whether the slope of the regression is significantly less than 1. How can I do this in R? I'm also interested in comparing the slopes of two regressions: fm1 <- lm (x ~ y) fm2 <- lm (a ~ b) and asking if the slope of fm1 is

Dear R help list, I am trying to do a logistic regression where I have a categorical response variable Y and two numerical predictors X1 and X2. There are quite a lot of missing values for predictor X2. eg., Y X1 X2 red 0.6 0.2 * red 0.5 0.2 * red 0.5 NA red 0.5 NA green 0.2 0.1 * green 0.1 NA green 0.1 NA green 0.05 0.05 * I am wondering can I combine X1 and

Hello, I have a question about using extreme value distribution in R. I have two variables, X and Y, and have pairs of points (X1,Y1),(X2,Y2), (X3,Y3) etc. When I plot X against Y, it looks like the maximum value of Y (for a particular X) is correlated with X. Indeed, when I bin the data by X-value into equally sized bins, and test whether the maximum value of Y for a bin is correlated with

Hi there, I am planning to write a small booklet on WxRuby2. The approach will be to "Document while you learn". I will be adding contents as and when I explore WxRuby2. I have just added a content skeleton. Please take a look at http://wiki.sagework.com/BooksWxRuby and let me know if you have any suggestions. I will keep the list updated about the progress. Cheers, Ganesh

Hi everyone Has anybody ever come across this, I want it to join automatically the recording files for me but it creates the wav files as I expect but it doesn't join them sadly, so eg: ls 1250623104.10-in.wav 1250628672.23-in.wav 1250630411.30-in.wav 1250623104.10-out.wav 1250628672.23-out.wav 1250630411.30-out.wav Here is my queues.conf snippet [testQ]

Hi All, I am having problems with a kickstart install of CentOS 8 When I try to do a completely automated install using PXE/UEFI it get to the point where it reads the kickstart config file.

Hi All, What I would like to do is the following: a) fit a probability function to a measured data set. This would be user specified, e.g., normal, lognormal, etc. and then b) take the probability function and plot it with the histogram of the measured data set. This function would be displayed as a smooth curve. This would involve "re-sizing" the probability function to match

Hi, I have been using some of the functions in r for classification purposes, chiefly lda, qda, knn and nnet. My problem is that the only one I can figure out how to represenent graphically is lda (using plot.lda). I have tried 'fooling' this function into accepting qda input for plotting but to no avail. I wonder if you have any suggestions? Thanks alot, Anne Marie Power Marine lab.

Hi Carlos " Agentcallbacklogin was deprecated in Asterisk 1.4 and eliminated from 1.6 so you now need to use Dynamic Agents. Although they claim that is is simple enough to replace that functionality with dial plan code I have yet to see a one line example that replaces everything the agentcallbacklogin command did.| I totally agree, I have never seen any example that makes it work.
