holidayNYSE missing some

The correct behavior is to shift the holiday to Friday (from Sat) or to Monday (from Sun).  I'm not actually using this for NYSE holidays but for power industry holidays and made a version to handle those changes as well as some other idiosyncracies.  Thanks for the suggestion though.

This is deliberate behavior.  If you check the code, the third-to-last
line is as follows:
    ans = ans[!(as.POSIXlt(ans at Data)$wday == 0 |
as.POSIXlt(ans at Data)$wday== 6)]


You could make an alternate version of holidayNYSE that omits this line,
if you like.

Hello,

I'm not sure if this is the correct list to email this too, but it
appears that at least in R 2.5.0 that the holidayNYSE function in
fCalendar does not include holidays that occur on Saturday.  E.g.
holidayNYSE(2004) does not list Christmas.

Thanks, John.

John,

I wrote this function for the NERC holidays you might have some interest 
in trying.  I also made some suggestions in a previous post in this list 
about this holidayNYSE problem, but did not hear from anyone on the 
feasibility of the suggestions.  This is also a problem with other US 
holidays, not just NYSE.  I would like to correct this for all the 
holiday functions but I do not want to have to overload the fCalendar 
functions every time I load fCalendar.

here is my holidayNERC()
