[R] frequency of items

[Jim Lemon]

Hi sri,
Maybe something like this?

has_values<-function(x,values) {
 if(is.list(x)) {
  return(sum(unlist(lapply(svlist,
   function(x,values) return(all(values %in% x)),c(11,12)))))
 }
}

svlist<-list(a=c(11,15,12,25),
 b=c(11,12),
 c=c(15,25),
 d=c(134,45,56),
 e=46,
 f=c(45,56),
 g=c(15,12),
 h=c(66,45,56,24,14,11,25,12,134))

has_values(svlist,c(11,12))
