Functions pwd() and swd() now return a list with the following components: s, the samples stored in a matrix nrepl * n, and iterations, the number of iterations run by the algorithm.
Functions stprod() and stsum() now return a list with the following components: mat, the standardized matrix, iterations, the number of iterations run by the algorithm, and conv, the convergence reached by the algorithm.
Spbsampling 1.3.3
CRAN release: 2020-03-31
Fixed typos in some examples.
Spbsampling 1.3.2
CRAN release: 2020-03-04
Usage
In the functions pwd(), swd() and hpwd() changed the name of the parameter nsamp in n.
Under the hood
In the functions pwd() and swd() introduced stopping criterion.
Spbsampling 1.3.1
CRAN release: 2019-12-16
Usage
In the functions pwd(), swd() and hpwd() changed the name of the parameter bexp in beta.
In the functions stprod() and stsum() changed the name of the parameter vecin con.
Under the hood
In the functions pwd() and swd() replaced arma::sort_index() with arma::stable_sort_index().
In the functions pwd(), swd() and hpwd() fixed the sample size check.
Spbsampling 1.3.0
CRAN release: 2019-08-04
New features
In the functions pwd() and hpwd() a new parameter called bexp has been introduced, which regulates the amount of spread of the samples. Default value set to 10.
In the function swd() the parameter bexp is now set to double and with default equal to 10.
Minor improvements
Minor improvements of guides:
some updates to the examples;
removed some non-ASCII characters;
inserted links to reference websites.
Spbsampling 1.2.0
CRAN release: 2019-03-12
Changed output of functions pwd(), swd() and hpwd() from a matrix of dimension (nsamp * nrepl) * 2 to a matrix of dimension nrepl * nsamp.
Removed Rdpack from Imports.
Minor improvements of guides.
Changed name of file heurprod.cpp to hpwd.cpp
Spbsampling 1.1.0
CRAN release: 2019-01-21
New features
Added a new function sbi() for compute the spatial index of a sample, implemented in C++ through the Armadillo library, using Rcpp and RcppArmadillo.
In the functions pwd() and swd() the parameter nrepl is now set to default at 1.
In the functions pwd() and swd() the parameter niter is now set to default at 10.
In the functions stprod() and stsum() the parameter differ is now set to default at 1e-15.
In the functions stprod() and stsum() the parameter niter is now set to default at 1000.
In the functions stprod() and stsum() there is no print for each convergence step anymore.
Improvements under the hood
The functions pwd() and swd() now take advantages of the Armadillo library.
The function stprod() is now implemented in C++ through the Armadillo library, using Rcpp and RcppArmadillo.
The function stsum() is now implemented in C++ through the Armadillo library, using Rcpp and RcppArmadillo.
The function hpwd() is now implemented in C++ through the Armadillo library, using Rcpp and RcppArmadillo.
In all the functions there are now checks about the correct inputs.
Minor improvements
Correction of some typos along the guides.
Miscellaneous
Added a NEWS.md file to track changes to the package.
