Check one-hot matrix

Description

These functions check whether the input is a one-hot matrix, i.e., a numeric matrix where each row contains exactly one entry equal to 1 and all other entries equal to 0.

Usage

check_one_hot_matrix(
  x,
  nrows = NULL,
  ncols = NULL,
  tolerance = sqrt(.Machine$double.eps)
)

assert_one_hot_matrix(
  x,
  nrows = NULL,
  ncols = NULL,
  tolerance = sqrt(.Machine$double.eps),
  .var.name = checkmate::vname(x),
  add = NULL
)

test_one_hot_matrix(
  x,
  nrows = NULL,
  ncols = NULL,
  tolerance = sqrt(.Machine$double.eps)
)

Arguments

x	[any] Object to check.
nrows	[integer(1)] Exact number of rows.
ncols	[integer(1)] Exact number of columns.
tolerance	[numeric(1)] A non-negative tolerance value.
.var.name	[character(1)] Name of the checked object to print in assertions. Defaults to the heuristic implemented in vname.
add	[AssertCollection] Collection to store assertion messages. See AssertCollection.

Value

Same as documented in check_matrix.
