Re: [R] Suggestions for vectorizing/double loop

Well, your second post is rather confusing too, as is your not reproducible code. If I understand correctly, you just want to change names of files in a directory according to some rules, which you did not clerly specify. First I am not sure if R is the best tool for it. Nevertheless, you do

Re: [R] separate mixture of gamma and normal (with mixtools or ??)

Dear Bert, thank you very much for your suggestion. You are right, ill-conditioning was sometimes a problem for 3 components, but not in the two-component case. The modes are well separated, and the sample size is high. My main problem is (1) the shape of the distributions and (2) the

Re: [R] Can R markdown do beamer palo alto theme?

Actually, I figured out that you can, but the syntax is different. You don't declare using \usedocument{beamer} \usetheme{PaloAlto}, instead, title and output are the correct syntax. Is there a full conversion list from Latex Beamer to Markdown Beamer? Thanks! On Mon, Jan 23, 2017 at 7:20 PM,

Re: [R] separate mixture of gamma and normal (with mixtools or ??)

Fitting multicomponent mixtures distributions -- and 3 is already a lot of components -- is inherently ill-conditioned. You may need to reassess your strategy. You might wish to post on stackexchange instead to discuss such statistical issues. Cheers, Bert Bert Gunter "The trouble with having an

[R] separate mixture of gamma and normal (with mixtools or ??)

Dear friends, I am trying to separate bi- (and sometimes tri-) modal univariate mixtures of biological data, where the first component is left bounded (e.g. exponential or gamma) and the other(s) approximately Gaussian. After checking several packages, I'm not really clear what to do. Here

Dear All. Apologies for posting a question regarding survival analysis, and not R, to the R-help list. In the past I received the best advices from the R community. The random censorship model (the censoring times independent of the failure times and vice versa) is one of the fundamental

Re: [R] R Graphics: Device 2 (Active)

You need to be clear in your own mind about the distinction between RStudio and R before you can communicate clearly about it. Specifically, we don't know how to debug problems with RStudio here, and what you describe sounds completely normal for the R Gui program that ships with R. It sounds

Dear T.Riedle, it is a 'combined' test, see ?causality for a formal description of the test statistic. If you would like results on an 'equation' by equation' approach, you could employ anova() on restricted and unrestricted lm-objects. Best wishes, Bernhard -Ursprüngliche

Re: [R] Suggestions for vectorizing/double loop

Hi In your case if you want to rename abot 600 items and your doble loop works it is not worth to vectorize it. However if you want to repeat such task often and you expect much bigger number of files vectorizing can speed things up and make them cleaner. Although I must admit that I do not

Dear T.Riedle, you cannot assign *all* variables as a cause at once. Incidentally, in your example, you missed a 'data(Canada)'. Having said this, you can loop over the variables names and extract the statistic/p-values. These are contained as named list elements 'statistic' and 'p.value' in
