Dear R experts,

I am learning the very useful XTS package, but cannot figure out the
purpose of some commands.

in particular, the .indexDate() command does not work as expected.

say:

x <- timeBasedSeq('2010-01-01/2010-01-02 12:00')
x <- xts(1:length(x), x)

then i can subset on date as follows:

x['2010-01-01']

however the .indexDate() command does not work as expected; in
particular the following does not return anything.

x[.indexDate(x) == '2010-01-01']


I am sure i am missing something - what is .indexDate() supposed to do?


thanks and best regards
