animate_cluster | R Documentation |
Generates an animation of a data stream clustering process.
animate_cluster( dsc, dsd, measure = NULL, horizon = 100, n = 1000, type = c("auto", "micro", "macro"), assign = "micro", assignmentMethod = c("auto", "model", "nn"), excludeNoise = FALSE, wait = 0.1, plot.args = NULL, ... )
dsc |
a DSC |
dsd |
a DSD |
measure |
the evaluation measure that should be graphed below the
animation (see |
horizon |
the number of points displayed at once/used for evaluation. |
n |
the number of points to be plotted |
type, assign, assignmentMethod, excludeNoise |
are passed on to |
wait |
the time interval between each frame |
plot.args |
a list with plotting parameters for the clusters. |
... |
extra arguments are added to |
Animations are recorded using the library animation and can be replayed (which gives a smoother experience since the is no more computation done) and saved in various formats (see Examples section below).
Note: You need to install package animation and its system requirements.
