Hi Everyone, I want to generate some random numbers according to some empirical distribution. Therefore I am looking for the inverse of an empirical cumulative distribution function. I haven't found any in R. Can anyone give a pointer? Thanks...

Hi all, When I write a script, I'd like to create a main() function so that I only need to type main() t re-run it. However, I'd like all the variables in main() to be global so...

Hi Benilton, I tried this. It sort of works, but the results are not very satisfactionary. The 3rd moment and higher do not match those of the original by a large difference. Do you have any better way to do...

Hi, I am really new at R. Does anyone know what is the real difference of vector and array, except that many operations that expect an array does not work on a vector? Thanks, Geoffrey _______________________________________________________=0A= =0A= =0A= The information...

Hi All, I am having great trouble doing something pretty simple. Here is what I did: > x <- read.table("clipboard") > dim (x) [1] 126 10 > typeof(x) [1] "list" > w <- array(x) > typeof(w) "list" Q1: How come after constructing...

Hi All, I'd like to know what is the best way to organize R code in multiple modules= and files. The R code we are writing is too much for a single file. Besides= , there are a lot of...

Hi Everyone, I am stuck with a simple problem. Suppose I have a vector x, and I want to calculate y[i]=3Dx[i+1]-x[i], it is very easy. I just need to write y<-x[2:length...

Hi Richard, 3D is automatically generated by the mailing list software, probably because I had ] followed by =3D without a space in the original post. What I meant was to calculate x[i] =3D x[i-1] + y[i-1...

I meant x[i] <- x[i-1] + y[i-1] and Y[i] <- y[i-1] + x[i] below. The mailing list software just keep adding 3D's. Sorry. -----Original Message----- From: r-help-bounces at stat.math.ethz.ch...

Yes, this solves my problem. Thanks for your help. -----Original Message----- From: Christos Hatzis [mailto:christos at nuverabio.com] Sent: Tuesday, December 26, 2006 10:58 AM To: Geoffrey Zhu; r-help at stat.math.ethz.ch Subject: RE: [R...
