[R] holidays effect

[elisia]

Unfortunately, my aim is to identify outliers in a time series, and I would
like the holidays, which have in general a higher value and shall not affect
such research.
If I run the detection of outliers on the whole time series,  while
maintaining the real values of the holidays,  I get results just as the
values corresponding to the festivities.
How can I solve this problem, by maintaining the daily data?
