slswFlexclust: Segment Level Stability Within Solution.
Description
Assess segment level stability within solution.
Usage
slswFlexclust(x, object, ...)
# S4 method for resampleFlexclust,missing
plot(x, y, ...)
# S4 method for resampleFlexclust
boxplot(x, which=1, ylab=NULL, ...)
# S4 method for resampleFlexclust
densityplot(x, data, which=1, ...)
# S4 method for resampleFlexclust
summary(object)
Arguments
x
A numeric matrix of data, or an object that can be coerced to
such a matrix (such as a numeric vector or a data frame with all
numeric columns) passed to stepFlexclust.
object
Object of class "kcca" for slwsFlexclust
and "resampleFlexclust" for the summary method.
y
Missing.
which
Integer or character indicating which validation measure
is used for plotting.
ylab
Axis label.
data
Not used.
…
Additional arguments; for details see below.
Value
An object of class "resampleFlexclust".
Details
Additional arguments in slswFlexclust are argument nsamp
which is by default equal to 100 and allows to change the number of
bootstrap pairs drawn. Argument seed allows to set a random
seed and argument multicore is by default TRUE and
indicates if bootstrap samples should be drawn in parallel. Argument
verbose is by default equal to FALSE and if TRUE
progress information is shown during computations.
There are plotting as well as printing and summary methods implemented
for objects of class "resampleFlexclust". In addition to a
standard plot method also methods for densityplot and
boxplot are provided.

al. (2018).
