What's the best object browser? Dear all, I have tried all the popular R IDE or editors like Eclipse, Komodo, JGR, Revolution... They all have fancy fucntions like auto completion, syntax highlight.... BUT, I JUST WANT A OBJECT BROWSER! The easiest way to view objects in R console is fix(), but you have no global view of all the objects in the workspace. Revolution has the best object

This is copy & paste from my session: > xyz<-as.vector(c(ls(),as.matrix(lapply(ls(),class)))) > dim(xyz)<-c(length(xyz)/2,2) > > allobj<-function(){ + xyz<-as.vector(c(ls(),as.matrix(lapply(ls(),class)))); + dim(xyz)<-c(length(xyz)/2,2); + return(xyz) + } > xyz       [,1]              [,2]        [1,] "a"               "character"  [2,]

Hi I'm writing a function that uses four parameters (scalars) and I need to run it in an iterative process (the parameters vary to find the minimum RSS). I don't want to use loops and so tried the do.call function. However it didn't work. My understanding is that the do.call simple runs the function replacing the arguments (scalars by vectors), instead of runing the function for

Hi there, Given 2 lists of integer vectors, i.e.: > lista1 $"1" [1] 1 34 5 $"2" [1] 2 1 $"3" [1] 3 10 15 > lista2 $"1" [1] 1 5 $"2" [1] 2 1 $"3" [1] 3 10 29 I want to obtain the union of both, defined as the union of the vectors, that is lista.union[[1]] <- union(lista1[[1]],lista2[[1]]): > lista.union

Dear all, may be somebody have ideas to my following problem: I have to multiplicate each element of a vector with his position in the sorted vector. This isn't a problem ;-) But now i have a weighting vector with the weight of each observation, and my problem starts. A little example (due to my bad english) maybe helps to understand: x<-c(10,40,50,100) # income vector for instance
