argo_filter: Select rows of Argo tables
In ArgoCanada/argodata: Locate, Download, and Read Argo Ocean Float Data

Description Usage Arguments Value Examples

These functions are intended to be applied to argo_global_meta() and other global index tables in the argo_global_*() family.

argo_filter_radius(tbl, latitude, longitude, radius_km)

argo_filter_rect(tbl, latitude_min, latitude_max, longitude_min, longitude_max)

argo_filter_date(tbl, date_min, date_max = Sys.time())

argo_filter_updated(tbl, date_update_min, date_update_max = Sys.time())

argo_filter_float(tbl, float)

argo_filter_parameter(tbl, parameter)

argo_filter_data_mode(tbl, data_mode)

argo_filter_parameter_data_mode(tbl, parameter, data_mode)

argo_filter_direction(tbl, direction)

`tbl`	A data.frame, ideally derived from `argo_global_meta()` and family. The column conventions used by the global indexes is assumed (e.g., columns `latitude` and `longitude` exist).
`latitude, longitude`	A location.
`radius_km`	A radius from the point described by `latitude` and `longitude`.
`latitude_max, latitude_min, longitude_max, longitude_min`	A rectangle describing the desired bounds. A rectangle where `longitude_min` is greater than `longitude_max` are interpreted as wrapping across the international date line.
`date_min, date_max, date_update_min, date_update_max`	A range of datetimes. Users are responsible for setting the timezone for these objects and are encouraged to used UTC.
`float`	A float identifier.
`parameter`	One or more (case insensitive) parameter names in which to search the `parameters` column of the bio-prof and synthetic-prof index files.
`data_mode`	One of "realtime" or "delayed".
`direction`	One of "ascending" or "descending"

tbl with rows that match the search criteria.
