An S4 class to store partial bootstrap correspondence analysis results.
idA character string specifying the unique
identifier of the corresponding matrix (UUID v4).
rowsA list of length three giving the vertices coordinates
(x, y) of the samples convex hull and a identifier
(id) to link each row to a sample.
columnsA list of length three giving the vertices coordinates
(x, y) of the variables convex hull and a identifier
(id) to link each row to a variable.
lengthsA list of two named numeric vectors giving the
convex hull maximum dimension length of samples and variables, respectively.
cutoffA length-two numeric vector giving the cutoff
value for samples and variables selection, respectively.
keepA list of two integer vectors giving the subscript
of the samples and variables to be kept, respectively.
In the code snippets below, x is a BootCA object.
x[i, j, drop]Extracts informations from a slot selected by
subscript i thru j (see examples). i should be one of
"rows" or "columns". Any unambiguous substring can be
given. j is a numeric, integer or
character vector or empty (missing) or NULL.
Numeric values are coerced to integer as by
as.integer (and hence truncated towards zero). Character
vectors will be matched to the name of the elements. An empty index
(a comma separated blank) indicates that all entries in that dimension are
selected.
x[[i]]Extracts informations from a slot selected by
subscript i. i should be one of "id",
"rows", "columns", "lengths", "cutoff" or
"keep". Any unambiguous substring can be given.
