"Apparently, R does not understand my Year-Month-Day "
I think, rather, you need to learn how R handles dates and times.
See here to begin, perhaps:
There are many R resources for dealing with data over time, many of which
are listed here, and others might be found by online searching.
There are also many tutorials on dealing with time data in R. Even a
cursory web search should find many.
... and of course someone may respond directly to your query here (but not
me, as I'm not that knowledgeable).
