difference_table: Difference Table

In mkoohafkan/RAStestR: Functions for testing RAS outputs

Description

Compute a difference table.

Usage

difference_table(d1, d2, relative = FALSE, partial = FALSE,
  difference.col = "Difference", time.col = "Time")

Arguments

d1	The first dataframe, considered the "base" result.
d2	The second dataframe, considered the "new" result.
relative	Logical: report differences as relative difference.
partial	If TRUE, only the overlapping times and columns will be processed.
difference.col	The name of the difference column to be created.
time.col	The time column name.

Value

A dataframe, with difference defined as d2- d1. if relative = TRUE, the difference is defined as (d2 - d1)/(0.5*(d2 + d1)).

Examples

simple.quasi = system.file("sample-data/SampleQuasiUnsteady.hdf",
  package = "RAStestR")
quasi.flow = read_standard(simple.quasi, "Flow")

difference_table(quasi.flow, quasi.flow)

quasi.double = operate_table(quasi.flow, fun = function(x) 2*x)
difference_table(quasi.flow, quasi.double)
difference_table(quasi.flow, quasi.double, relative = TRUE)
