Dear R users, the first 1.0 version of the rPref package is now on CRAN. rPref allows to select the Pareto-optimal tuples from a data set, also called Skylines in the database community. For example, optimal tuples from mtcars according to "high(mpg) * high(hp)" (where "*" is the Pareto operator) are those cars, for which no other dominating car exists. There, a car dominates another ca...

Buenas a todos, Lo primero agradecer todas las respuesta sque tuve en el tema de Bootstrap dataframe, que por estar de baja no he podido agradecer. De aquel tema salió una sugerencia que me parece muy interesante y que a dia de hoy no soy capaz de hacer de una manera optima. Lo que quiero hacer es coger un dia al azar de todo el periodo, y a partuir de ese dia, coger por ejemplo los 20 dias siguientes. Recuerdo que para cogerlos al azar hacia lo siguiente: set.seed(121) final<-0 nuevo<-0 for(i in 1:100000){ nuevo<-sample(datos$pedidos,replace=T) final[i]&...

I have had problems with the function optimize/optimise for maximising/minimising a function of one variable. It seems to get easily fooled by local optima. Obviously this can happen to any numerical optimiser but some of the examples I have a pretty disappointing. Any comments of suggestions of a better R-function? --------------------------------------------------- Chris Lloyd Associate Professor, Australian Graduate School of Management UNSW SYDN...

...wess line lines(lowess(y[x2==0]~x1[x2==0])) I can also avoid the problem by coercing x1 and x2 to be vectors. So, I don't need help to solve the problem. But, it seems an odd problem since it affects one plotting method, but not the other, and it actually causes R to crash.

Hi all, I am using the "svm" command in the e1071 package. Does it have an automatic way of setting the "cost" parameter? I changed a few values for the "cost" parameter but I hope there is a systematic way of obtaining the best "cost" value. I noticed that there is a "cross" (Cross validation) parameter in the "svm" function. But I
