[R] Problem to create a matrix polynomial

Dear all R users, I was trying to create a polymonial using the polynom() of PolynomF package. My problem is, if I pass coefficients as simple numerical values, it is working, but for matrix coefficient it is not. Here is my try: library(PolynomF) z - polynom() ## following is working p1 - 1-

[R] Merging list object

Hi, I have created following list object : library(zoo) dat - vector(list) for (i in 1:4) dat[[i]] - zooreg(rnorm(i*10), start=as.Date(2000-01-01), frequency=1) dat[[1]] 2000-01-01 2000-01-02 2000-01-03 2000-01-04 2000-01-05 2000-01-06 2000-01-07 2000-01-08 2000-01-09 2000-01-10

[R] Need help on matrix manipulation

Dear all, Ket say I have 3 matrices : mat1 - matrix(rnorm(16), 4) mat2 - matrix(rnorm(16), 4) mat3 - matrix(rnorm(16), 4) Now I want to merge those three matrices to a single one with dimension 4*3=12 and 4 wherein on resulting matrix, row 1,4,7,10 will be row-1,2,3,4 of mat1, row 2,5,8,11

Re: [R] Simulation of VAR

Yes I looked into dse package. Here I have implemented two approach for simulation like following : library(dse) A1 - matrix(rnorm(16),4) A2 - matrix(rnorm(16),4) mu - rnorm(4) sigma - matrix(c(0.006594712, 0.006467731, -0.000254914, 0.005939934, 0.006467731, 0.006654184, -0.000384097,

[R] Simulation of VAR

Dear all, is there any package/function available which simulates a co-integrating VAR model once the model parameters are input over some arbitrary horizon? Please let me know anyone aware of that. Thanks -- View this message in context:

[R] Replacing elements of list

Dear all, I have following two list object, both are basically collection of matrices : dat1 - matrix(rnorm(25*6), ncol=6) dat1 - split(dat1, seq(5,25,by=5)) dat1 - lapply(dat1, matrix, ncol=6) dat2 - matrix(rnorm(25*4), ncol=4) dat2 - split(dat2, seq(5,25,by=5)) dat2 - lapply(dat2, matrix,

[R] A question

Hi all, I have a expression like that : rep(2,4) [1] 2 2 2 2 Now I want to write it as through some automated way. Is there is function for doing that? I have tested with paste(), but count not get any desired result. Thanks, -- View this message in context:

[R] RHTMLForms Package

Can anyone tell me from where to download the package RHTMLForms ? CRAN seems not holding this anymore. I am using Windows Vista OS. Thanks -- View this message in context: http://n4.nabble.com/RHTMLForms-Package-tp997672p997672.html Sent from the R help mailing list archive at Nabble.com.

[R] Matrix to list object

let consider following matrix : mat - matrix(rnorm(45), 15) Now I want to convert it to a list object mat_list, which will have 15 elements and each element will again be a matrix with 3 rows and 3 columns. How can I do that? Thanks, -- View this message in context:
