YEAR

<p>YEAR is a user provided vector of the years in the TMAX and TMIN data used with calc_si.
YEAR is not used in the calc_si (or any internal functions), but it is used for
plotting the results in the example code.
Example of YEAR is available if one calls data("BatonRouge")</p>

Computes the extended spring indices (SI-x) and false spring
exposure indices (FSEI). The SI-x indices are standard indices used for
analysis in spring phenology studies. In addition, the FSEI is also from
research on the climatology of false springs and adjusted to include an
early and late false spring exposure index. The indices  include the
first leaf index, first bloom index, and false spring exposure indices,
along with all calculations for all functions needed to calculate
each index. The main function returns all indices, but each function can
also be run separately.
