Hi I have estimated parameters of my data with mlogit and the following commands. I would like to know also the McFadden R^2 and the intercept, could soweone tell me how that can be done? library(RODBC) library(mlogit) library(foreign) z<-odbcConnectExcel("D:\\MALLI11ARVOT.xls") y<-sqlFetch(z,"Taul1") Mallidata=mlogit.data(y,choice="Voittaja",shape="long&quo...

Hi, I''ve run linux off an on for several years. Recently I''ve been using windows (simply for ease), but have gotten so fed up with stability and what not. I had read good things about xen, so I installed suse and was hoping to not give up the 10% of things that I need windows for. I''ve still got windows on a partition and was wondering if I could boot that, but wanted

Dear R Users I would like to use optim function to optimize a function. I read help but I couldn't find what I need: is it possible to get information after each iteration, for example as there is in MATLAB: Gradient's Iteration Func-count f(x) Step-size infinity-norm 0 24 388.976

Dear R Users, Is it possible to make file names dependent on a changing variable? For instance. I generate random numbers in a loop and at each iteration I want data to write to file (I do not want to write everything in one file using 'append'): for (i in 1:50){ x<-matrix(runif(100, min=0,max=1),nrow=5,ncol=20) Write(t(x),file="Data_i.txt",ncolumns=5,sep="\t") }

Dear R Users, I have a matrix A, and I want to change every value of this matrix if these values are greater than an assuming value. For a vector it is simple, e.g. a<-c(1:10); a[a>5]<-0. Of course, I can change matrix to vector, assign a value then change vector to matrix. But does there exist simpler way? Any suggestion are appreciate. Rob

Dear R Users, I hope that there is someone who has an experience with a problem that I describe below and will help me. I must buy new desktop computer and I'm wondering which processor to choose if my only aim is to speed up R. I would like to reduce a simulation time - sometimes it takes days. I consider buying one of them (I'm working under Win XP 32 bit): 1. Intel Core2 Duo E6700

...build seem to have the same name for both the dom0 and domU instances. I get one kernel named vmlnuz-2.16.6-xen Is this expected? Although the dom0 boots, I ma having a crappy time getting a virtualized OS to boot and am trying to see if this is the problem.
