Dear Uwe and Spencer,

Thanks for replying so soon. The R version I wrote is indeed R 1.9.1, and the package is stats. Sorry I didn't wrote it in my first email. I've have tried to use the comments you gave, and simplified my function.
It is changed to:

> Kalm = function(x){

+ t=array(c(-1.4248, 2.5, .1250, 20, -19.3183, .6667, .1, .0667, 1.7945), dim=c(3,3)) + h=0.5; + r=array(c(1,0,0,0,1,0,0,0,1),dim=c(3,3)); + q=1; + v=r*q*t(r); + a=10.14286; + z=array(c(.3574, 0, 0, 0, 0, 0, 0, 0, .2), dim=c(3,3)) + p=array(c(1,0,0,0,1,0,0,0,1),dim=c(3,3)); + pn=array(c(1,0,0,0,1,0,0,0,1),dim=c(3,3)); + kal=KalmanSmooth(x,list(T=t,Z=z,h=h,V=v,a=a,P=p,Pn=pn),nit=0) + kal}

>Kalm(deb)

Wonderfully it is running quite well now. Thank you for your spare time.
Best regards,

Pieter Hazenberg

Uhhhh .... thanks, Spencer. My apologies to Pieter. Indeed, looks like I forgot to upgrade my R version on the machine at home. I only did so in my office and on my laptop. Uwe
