hwPath.
It will generate either a single value for every ensemble member, if
city_specific is set to FALSE, or a value for every city, if
city_specific is set to TRUE.
apply_hw_projections(hwPath, FUN, city_specific = FALSE, ...)gen_hw_set. The file at the specified filepath must
conform exactly to the format of the extreme event files created by
gen_hw_set.hwPath.
This function must only take one argument, hw_datafr, which
identifies a dataframe as generated by gen_hw_set. The
function should output a single value (e.g., average heat wave length)
when applied to the full dataframe.FUN.
