What I'm trying to do is have plots and summary statistics of x (autocorrelations for example) where x refers to the data in using, and I thought decomposing would be the way to go about it. P.Dalgaard wrote: > > ethanhaas wrote: >> I simply called it information but I can also call it data if

[R] Hep on using GAM() in R

Dear friends, I met some problem on using GAM() function in R. Any help or suggestions are greatly appreciated. # My programs and problems are list below# library(splines) library(gam) point<-read.csv("d:/gam.csv",sep=",",header=TRUE) #read the data gam.opt<-gam(mark~lo(x,y,span=0.2)+lo(lst

Re: [R] Package compilation

The easiest way is to read (in the manual) If you have only a source package that is known to work with current R and just want a binary Windows build of it, you could make use of the building service offered at win-builder.r-project.org. Is that what was too hard for you? If so, you ar

Re: [R] how to obtain the CPU time of my program

Hi, first of all 'sorry' for my rather late post on this topic... Did you already came across the R command 'Rprof' ? This might help you to find answers to your problem in terms of CPU time/command. I use 'Rprof' like this: >Rprof() >source("yourCode.R") >Rprof(NULL) This produces a file calle

[R] Package compilation

Hello, Is there an easy way to compile a package so that it can be installed as a binary file under Windows? Now I have the source code. I am not used in compiling, and the documentation seems too hard for me, so an easy way would be great. Best regards, Dani -- Daniel Valverde Saubí Grup de

Re: [R] Getting error message using R: Please help (it's coursework due in on Friday)

I simply called it information but I can also call it data if you wish, it doesn't make a difference. The timeseries is simply the time series of this data between the two dates and using is the data up to 1990 as opposed to 1994. P.Dalgaard wrote: > > ethanhaas wrote: >> I've been trying for t

Re: [R] Matrix Inversion

Hello Wang matrix bb is symmetric positive semidefinite, so algebraically the eigenvalues are nonnegative. I would use bb <- crossprod(b) to calculate bb (faster and possibly more accurate) Look at eigen(bb,TRUE,TRUE)$values (see ?eigen for the meaning of the arguments) to see how many very s
