here.com isoline routing using R - df as result?

This is related to here.com and the developer side on a freemium account.

Problem: Is creating an empty dataframe or only ID instead of giving me a full data table with a polygon each row based in the isoline routing based in time.

Below piece could please guide anyone into a way to solve this? Code obtained through this example

1. My input centroids as df + my funcion
2. Bad result, but one by one it works perfectly

set_key(api_key = "12345") # not it
df <- structure(list(address = c("853, Boul. Albiny-Paquette", "790 Boul. Wilfrid-Lavigne",
