New feature results

Create a new FeatureResults object to store results for a solution.

new_feature_results(feature, held, id = uuid::UUIDgenerate())

Arguments

feature	Feature object.
held	numeric proportion of the feature held by the solution. (e.g. 0.1 = 10%).
id	character unique identifier. Defaults to a random identifier (uuid::UUIDgenerate()).

Value

A FeatureResults object.

Examples

# find data file paths
f1 <- system.file(
  "extdata", "projects", "sim_raster", "sim_raster_spatial.tif",
  package = "wheretowork"
)
f2 <- system.file(
  "extdata",  "projects", "sim_raster", "sim_raster_attribute.csv.gz",
  package = "wheretowork"
)
f3 <- system.file(
  "extdata",  "projects", "sim_raster", "sim_raster_boundary.csv.gz",
  package = "wheretowork"
)

# create new dataset
d <- new_dataset(f1, f2, f3)

# create new variable
v <- new_variable_from_auto(d, index = 1)

# create new feature
f <- new_feature(name = "Intact Alvar", variable = v)

# create a feature results object to store results for the feature
fr <- new_feature_results(f, held = 0.8)

# print object
print(fr)
