...om their appearance, yet the str() lists them in date order, not alphabetical order. So if I execute library(quantmod) #in fairness, I did not include this last time and my example was therefore not reproducible. Apologies to Bert and everyone else #for not following the posting guidelines. aapl_total<-getOptionChain("AAPL", NULL) How could I then get the subset of the entire list which only has expiry dates in 2019, or more specifically, in Mar or Apr or May of 2019?

Hi R Helpers, Is it possible to interpret the top level of the list as a date after downloading all the option chain data for a ticker? For example, after I run aapl_total<-getOptionChain("AAPL", NULL) the top descriptor of the lists is a date (Mar.09.2018, Mar.23.2018, etc.). So if want to subset down to those parts of the list that correspond to say, (expiration) year=2019; or say, Mar or Apr or May of 2019, is this possible? Guidance would be ap...

You know options but you are confused about maturity dates, i.e. expiry? In information in that list (ie along the date dimension) is the expiry; at each date you have another list for both puts and calls, and inside each of those a grid given by the
