to_widetable: Reformat As Wide Table

In mkoohafkan/RAStestR: Functions for testing RAS outputs

Description

Reformat RAS data from long table format (i.e. output of to_longtable) to wide table format (key values are mapped to individual columns).

Usage

to_widetable(d, key.col, value.col, key.prefix, key.attr = c("River",
  "Reach"))

Arguments

d	The data table, i.e. output from to_longtable.
key.col	The name of the column holding data keys.
value.col	The name of the column holding data values.
key.prefix	Text to prepend to the new columns created from keys in key.col.
key.attr	Columns to maintain as attributes in the resulting wide-format table. By default, columns "River" and "Reach" will be searched for and maintained as attributes in the output wide-format

Value

The original data table in wide format.

Examples

simple.quasi = system.file("sample-data/SampleQuasiUnsteady.hdf",
  package = "RAStestR")
quasi.volincum = read_sediment(simple.quasi, "Vol In Cum")
quasi.long = to_longtable(quasi.volincum, "VolIn")
to_widetable(quasi.long, "Station", "VolIn")
to_widetable(quasi.long, "GrainClass", "VolIn")
