Approximate Entropy?
Dear guRus, is there a package that calculates the Approximate Entropy (ApEn) of a time series? RSiteSearch only gave me a similar question in 2004, which appears not to have been answered: http://finzi.psych.upenn.edu/R/Rhelp02a/archive/28830.html RSeek.org didn't yield any results at all. Happy holidays (where appropriate), Stephan

R Commander and FactoMineR
Dear Users, I helped to install R Commander and FactoMineR to one of my collegaues. He wanted to do an MCA. Selecting three variables and using the default settings results in only one graph, the variables representation, where he gets three points for the three variables (which is totally fine). Running the code (output of the point-and-click method) EuTop100.MCA<-EuTop100[,

Generate combination of strings
Hey all, I am trying to generate a number of vectors with string combinations. The below code solves my initial problem, however I would prefer not hardcoding the positions of the 'objects' as in the future the number of 'objects' could increase. Is there a way to loop over these objects and generate the same output? The same goes for the 'maxspacer'. Thanks a whole

Literature analysis
Dear all, i am new in R. I am writing a review paper about batteries. However, i am interested in analyzing all the papers by keywords, author, references and year. This could be done by "refviz" a software, which is only running on windows machines and which is not free. So my question to you is, is it somehow possible to write a script that can do all of this work? And if yes, with

Only 5 tests out of 376 currently failing!
Good news! SuperRedCloth is down to just five failing tests! I was down to 10 or so in mid-February but then I added test cases from "The official reference manual for Textile 2", which added 97 new tests, many of them failing. I''m happy to say, they''re almost all passing now. Four of these last five I just need to check with you on before I deviate from

Hi, I am trying to run the command "forward.sel.par," however I receive the error message: "Error: could not find function 'simpleRDA2'." I have the vegan library loaded. The documentation on "varpart" has not helped me to understand why I cannot call this function. Maybe I am missing something obvious because I am still an 'R' novice. Below is a

I just realised I hadn't updated the version of PHP Markdown and Extra on the dingus as I pretended I did in my two announcements. It is now fixed: PHP Markdown 1.0.2b7 and PHP Markdown Extra 1.1b1 can now be tested on the dingus. <http://www.michelf.com/projects/php-markdown/dingus/> Sorry for any inconvenience.
