Hi to all,
I was investigating a way to write with Rcpp a function that removes all
the NA values in the input vector.
And before doing so, I was playing with Rcpp, writing this function:
library(inline)
cppFunction('
Vector<INTSXP> na_test(const Vector<INTSXP>& x) {
return setdiff(x, Vector<INTSXP>::create(::traits::get_na<INTSXP>()));
}
')
That works in this way:
na_test(c(1, NA, NA, 1, 2, NA))# [1] 1 2
How can I write a generalized version of this function, for example?
I've made an attempt (see stackoverflow related
question<http://stackoverflow.com/questions/15953768/templated-rcpp-function>).
It compiles but it doesn't work as expected.
Any suggest or example?
Thanks in advance,
Leonardo Di Donato
