Sorry, it's simple question: example : > data.test label value 1 one 21.35746 2 two 22.07592 3 three 20.74098 > I would like the return : label value 3 three 20.74098 1 one 21.35746 2 two 22.07592 Anyone can help it? Thanks, regards Unung Istopo

Sorry, to solve your question I had tried: data(faithful) kmeans(faithful[c(1:20),1],10) Error: empty cluster: try a better set of initial centers But when I run this a second time it will be ok. It seems, that kmeans has problems to initialize good starting points, because of the random choose of these starting initial points. With kmeans(data,k,centers=c(...) the problem can be solved.

Dear all I apologize for cross-posting, but first it is accepted custom to thank the repliers and give a summary, and second I have still the feeling that this problem might be a general statistical problem and not necessarily related to microarrays only, but I might be wrong. First, I want to thank Robert Gentleman, Mark Kimpel and Mark Reiners for their kind replies. Robert Gentleman kindly

On 16 Apr, Unung Istopo Hartanto asked about using R library 'foreign' to import SPSS Data Entry data files. SPSS Data Entry is an application that allows for the creation of formatted data entry forms (as does EpiInfo, Epidata and CSPro (all free downloads)). As such it creates the usual SPSS data files, but adds forms information, which the 'foreign' package does not know how

Hi John, why not try something newer than CentOS 6.8 ? Maybe not the latest 8.1 but 7.7 is quite recent and stable. Your (integrated) video card is : Intel?

Hi, I haven't seen recent information on wine and twain. I already sent a similar mail to wine-users and, in a second step to wine-devel, but without any information back until now. May be the trick "Wine and twain" to "Wayne and twin" will give me more chance to be listen. Or may be my question is really stupid? >From a recent mail that I got, the problem is of

Hello, I have an Intel NUC7PJYH running CentOS 6.8. This is a NUC with standard USB, 1GbE and 2*HDMI. Installation was no problem providing acpi=off. The problem is that by default the two displays are mirrored and I can?t seem to separate them. I can only see one HDMI port from CentOS. I need to see both HDMI ports discreetly. Can you please help. Regards, Mark Woolfson MW Consultancy Ltd

Dear R Users?? I woould like to generate mixture model data. I try two type method as followings two method, can anyone tell me which is right? or better? 1. generate two vectors data y1 and y2 from f1 and f2 seperately, and calculate y=alpha1*y1+alpha2*y2, 2. generate prob=unif(1), if prob <alpha1 y=y1, else y=y2. Can anyone give me some idea? Thanks so much! Goeland goeland at

Hi! I need to fit a data that shows up as two gaussians partially superimposed to the corresponding gaussian distributions, i.e. data=c(rnorm(100,5,2),rnorm(100,-6,1)) I figured it out how to do it with mle or fitdistr when only one gaussian is necessary, but not with two or more. Is there a function in R to do this? Thank you very much in advance, Luis

I have not followed the history of this thread, but I am quite flummoxed as to why the OP is rewriting code to estimate parameters from an univariate Gaussian mixture model when alternatives such as EMCluster (which generally appears to handle initialization better than MClust) exist. Or perhaps there is more to it in which case I apologize. But I thought that I would make the OP aware of the

Recently, I have been working with some data that look like two overlapping gaussian distributions. I would like to either 1) determine the mean and SD for each of the two distributions OR 2) get some (bayesian ?) statistic that estimates how likely an observation is to belong to the left-hand or right-hand distribution In case I'm using the wrong language, my data looks something like
