NEW FEATURES
* intervals are now more useful and lubridate has more ways to manipulate
them. Intervals can be created with %--%; modified with int_shift(),
int_flip(), and int_standardize(); manipulated with intersect(), union(),
and setdiff(); and used in logical tests with int_aligns(), int_overlaps(),
and %within%. lubridate will no longer perform arithmetic between two
intervals because the correct results of such operations is no more obvious
than the correct result of adding two dates. Instead users are encouraged
to use the new set operations or to directly modify intervals with
int_start...

Buenas
tardes,
Tengo un
data frame denominado “trabajadores”, que cubre desde el 1 de
enero de 1997 hasta el 30 junio de 1999, con 3 columnas: Identificador (ID), la
fecha de entrada en la empresa (ENT) y la fecha de salida (SAL). Deseo localizar
aquellos trabajadores que, durante dicho periodo, NO han llegado a pasar un 31
de diciembre y un 1 de enero seguidos (cambio de año) como asalariados
