POT package

Perhaps you could tell us what function you are talking about.... npy
is not part of the POT package in the version on my machine and those
letters don't seem to show up anywhere consecutively at all on my
system, according to ??npy. Similarly, this trick produces no results:
sapply(ls("package:POT"), function(f) sum(grepl("20945",deparse(get(f)))))

Hi Sir It is requested to please tell the reason why the range of c(20945, 209547) is used in this function

I'm not particularly familiar with EVT but it seems that here the term exists to scale down the time base to that wherein extreme values were identified. Just a hunch though... If you want more accurate clarification you may wish to contact the package maintainer, but to be honest I wouldn't worry too much about it -- it seems very specific to the problem he was addressing in the vignette, not to the inner workings of the package.
