[R] Small Area Estimation with R

["Gómez Rubio, Virgilio"]

Dear R users,

First of all, excuse for the cross posting. I am working on Small Area 
Estimation and I was
wondering if someone knows about software to compute GREG, syntehtic and/or
(E)BLUP estimators with R.  I know that it should be posible to compute 
those
estimators using package nlme (for example), but I  thought that perhaps 
someone had already
written  some code to include spatial and/or spatio-temporal random effects.

Thanks in advance. Best regards,

Virgilio
