My program deals with clustering. Apart from dataset user has to specify some details concerning clusters. There are two ways to approach that: you specify number of clusters or prepare list of clusters' descriptions.
args <- list(dataset=points, K=5)
args <- list(dataset=points, clusters=list(
list(type="spherical",radius=4),
list(type="covariance",covMat=matrix)
)
next you call proper function (my program) in R with args as the argument.
classification <- CEC(args)
I would like to prepare CEC like below
SEXP CEC(SEXP args) {
Rcpp::List list(args);
arma::mat dataset = Rcpp::as<arma::mat>(list["dataset"]);
if(list.contains("K")) {
//something
} else if(list.contains("clusters")) {
//something
}
}
I cannot find any API for List or example how to do that. Moreover, I study headers of Rcpp but definition of List which is typedef Vector<VECSXP> List ;
is hardly helpful.
Is there anything I can use instead of list.contains()
?
