getSymbols( src="yahoo") will let you set any time as the from parameter.

getSymbols("^GSPC", from="1900-01-01") should do what you want.  The
'to' is always today's date.


P.S. The data editor issue is one you should ask on R-help, as that
would have nothing to do with the quantmod/finance side of things.
