The NA comes from your max value and it's due to your seq(0, max(x),
by = 1) creating a sequence that will stop BEFORE your decimal max
(x)... Therefore the element of x which equals 1355.888 is not part of
the allowed outputs of cut().

Are you sure you would not rather use either round (x) or ceiling
(x)? Not sure however what you really want from this...
