[R-pkgs] SamplingStrata: new version on CRAN

[Giulio Barcaroli]

Dear all,

this is to announce that a new version of*SamplingStrata*  
       is available on CRAN.*SamplingStrata*  is a package for the
       optimization of stratified sample design. This new version (the
       1.5) contains a lot of news. In particular:

- there is now the possibility to cover also*spatial sampling*,
       whenever the units in sampling frame are geo-referenced (method =
       "spatial" in*optimStrata *function);

- the use of the function*optimStrata *(a wrapper that call different
	optimization functions) greatly simplifies the handling of*takeall *
	strata;

- when models are used in order to take into account the*anticipated variance*  of target variables, a new function (computeGamma)
       permits to evaluate*heteroscedasticity*  in order to
       correctly calculate the overall variance in strata.

A*cheatsheet*  is available in the /docs/inst directory.

You can find the whole documentation at

Giulio Barcaroli
