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
.
rows
A three columns data.frame
giving the vertices
coordinates of the samples convex hull and a identifier to link each row to
a sample.
columns
A three columns data.frame
giving the vertices
coordinates of the variables convex hull and a identifier to link each row
to a variable.
lengths
A two columns data.frame
giving the convex hull
maximum dimension length of each sample and a identifier to link each row to
a sample.
cutoff
A length-one numeric
vector giving the cutoff
value for sample selection.
keep
A named numeric
vector giving the subscript of
the samples to be kept.
