[R-SIG-Finance] Trying to Extract Option Quotes with R

It looks like some of the dependencies don't load automatically. I was using
R x64 3.2.2:

1) Updated my R to the later version
2) I installed package jsonlite  ("package:"jsonlite"cannot be loaded.")
3) I installed package curl ("Error: Required package curl not found. Please
run: install.packages('curl')"
4) I updated to R x64 3.2.5 then R x64 3.3.3 re-installed the above.

I now get

" Error in data.frame(Strike = strike, Last = lastprice, Chg = change, Bid =
bid,  : 
  object 'contractsymbol' not found"

The complete output is now:

I executed the following commands in R:

     optData = getOptionChain( "XOM", Exp=NULL )

The last command returned NULL. What am I doing wrong?
