An S4 class to store partial bootstrap correspondance analysis results.
# S4 method for BootCA
[[(x, i)# S4 method for BootCA
[(x, i, j)
A BootCA object from which to extract element(s).
Indices specifying elements to extract.
i is a character string matching to the name of a slot.
j can be missing or NULL,
a numeric or character vector.
Numeric values are coerced to integer as by
as.integer (and hence truncated towards zero).
Character vectors will be matched to the names of the object.
[[: Extracts informations from a slot selected by subscript
i.
[: Allows to select a slot thru j.
rowsA three columns data.frame giving the vertices
coordinates of the samples convex hull and a identifier to link each row to
a sample.
columnsA three columns data.frame giving the vertices
coordinates of the variables convex hull and a identifier to link each row
to a variable.
lengthsA two columns data.frame giving the convex hull
maximum dimension length of each sample and a identifier to link each row to
a sample.
cutoffA length-one numeric vector giving the cutoff
value for sample selection.
keepA named numeric vector giving the subscript of
the samples to be kept.
