Re: [R] Linux editor like WinEdt?
Le Fri, 10 Mar 2006 16:52:28 +, Ana Patricia Martins a écrit : I initiate in R - Linux and I've some problems to find an editor with R interface as like RWinEdt for WinEdt. This is not a strict equivalent to WinEdt, but TeXmacs is extremly intersting. TeXmacs is a free wysiwyw (what you see is what you want) editing platform with special features for scientists. See : http://www.texmacs.org/tmweb/home/welcome.en.html It supports binding with R [1] but also with several other useful softwares [2].

Re: [R] Optimization problem: selecting independent rows to maximizethe mean
Le Wed, 01 Mar 2006 13:07:07 -0800, Berton Gunter a écrit : 2) That the mean and sd can be simultaneously optimized as you describe-- what if the subset with maximum mean also has bigger than minimal sd? Then you have two choices : 1) balance the two objectives with weights, according to the importance you give to each one 2) get a list of non-dominated solutions (a Pareto front) Does R have packages for such multi-objectives optimization problems ? Moreover, does it have a package for difficult (i.e. NP-hard) problems ? -- nojhan __ R-help@stat.math.ethz.ch mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide! http://www.R-project.org/posting-guide.html
