NanotimeToNanotime: nanotime to nanotime round-trip demo

In RcppInt64: 'Rcpp'-Based Helper Functions to Pass 'Int64' and 'nanotime' Values Between 'R' and 'C++'

nanotime to nanotime round-trip demo

Description

This function takes an nanotime-valued input vector, converts it to the equivalent int64_t vector in C++, displays each element after first adding one, and returns the modified vector.

Usage

NanotimeToNanotime(vec)

Arguments

vec	A nanotime-classed vector from R

Value

A modified nanotime vector where each element increased by one

Examples

# generate all powers of 10 fro 0 .. 18
if (requireNamespace("nanotime", quietly=TRUE)) {
    v <- nanotime::as.nanotime(10^seq(0,18))
    # pass them to function which will add one to each, print  and return
    NanotimeToNanotime(v)
}
