Manual classification object.

An S3 class for handling manual classification.

manual_classification(
  assignments = factor(),
  cutoff = NA_real_,
  transform = identity
)

Arguments

assignments	A factor vector of cluster assignments.
cutoff	The value used for the manual classification.
transform	A callable (function) to transform the data before applying the cutoff classification.

Value

A manual classification that behaves like a factor.

Examples

# An empty classification.
manual_classification()
#> factor(0)
#> Levels: 

# The numeric assignments will be turned into a factor.
manual_classification(c(1, 2, 1, 2, 1, 1), cutoff = 4000)
#> [1] 1 2 1 2 1 1
#> attr(,"cutoff")
#> [1] 4000
#> attr(,"transform")
#> function (x) 
#> x
#> <bytecode: 0x7fd9048bf380>
#> <environment: namespace:base>
#> Levels: 1 2

# Provide a different function used to transform the data before
# applying the cutoff.
manual_classification(
  c("a", "a", "b", "a", "b"),
  cutoff = 2.5,
  transform = log10
)
#> [1] a a b a b
#> attr(,"cutoff")
#> [1] 2.5
#> attr(,"transform")
#> function (x)  .Primitive("log10")
#> Levels: a b
