One thing that comes to mind immediately is the 'blotter' package
which I believe is designed to handle and track multiple instruments.
A sloppy temporary solution I guess would be to do some type of lookup
or a flag that denotes which instrument is an option and apply the VaR
methodology
What kind of time series data? Finance? Econometrics?
The 'quantmod' package allows for downloading of stock and FRED data
online for analysis. I believe PerformanceAnalytics also has some
datasets as well.

I think it depends on your particular domain, mine is in finance:
Quantmod
PerformanceAnalytics
