Checks whether theta belongs to space.
A count vector belongs when its entries are non-negative whole
numbers summing to n_trials; tol is unused.
Arguments
- space
A space.
- theta
A point of the space.
- tol
Tolerance.
Examples
s <- simplex_region(vertices = diag(3))
contains(s, c(1 / 3, 1 / 3, 1 / 3))
#> [1] TRUE
contains(s, c(2, -1, 0))
#> [1] FALSE
# A count space is a space too, and answers the same question.
contains(count_space(n_trials = 4L, k = 3L), c(2L, 1L, 1L))
#> [1] TRUE
contains(count_space(n_trials = 4L, k = 3L), c(2L, 1L, 0L))
#> [1] FALSE
