subset_table: Subset table

In ECCC-MSC/Basin-Delineation: Finds upstream area and upstream stations

Description

Subset table

Usage

subset_table(table, pattern, stn_list)

Arguments

table	a data table created from initialize_matrix_from_stations. An (n x n+1) data.table with first column named "ID" and all other columns named according to station number. Row i and column i+1 should correspond to the same station.
pattern	regular expression to match station names.
stn_list	a list of stations to include in the subset. Ignored if pattern is provided

Details

to return only stations within a particular drainage area (e.g. stations beginning with '02'), use pattern='^xx' where xx is the drainage basin number. So "^01" would return stations from NS & NB and "^08" would return stations from BC

Value

a data.table containing a subset of rows and columns from the input table
