## S3 method for class 'drifter}(x, subset, \dots)':
subsetundefined- x
{a drifter
object.}
- subset
{a condition to be applied to the data
portion of
x
. See Details .}
- ...
{ignored.}
This function is somewhat analogous to
subset.data.frame
, but only one independent variable may be
used in subset
in any call to the function, which means that
repeated calls will be necessary to, subset based on more than one
independent variable. Subsetting may be by time
, latitude
,
longitude
, or profile
.
A new drifter
object.
