Dear members,

AND:

           HINDUNILVR.NS.Open HINDUNILVR.NS.High HINDUNILVR.NS.Low HINDUNILVR.NS.Close
2007-01-09              210.1              214.2             208.7              209.85

2007-01-09              5474633               150.3468

BUT:

> head(testOHLC[-"2007-01-09"])
 Error in -"2007-01-09" : invalid argument to unary operator

How do remove rows with certain dates in an xts object? This doesn't work:

x[-dates] (however, this does: x[dates])

Many thanks in advance......

Yours sincreley
