plotDistances {clst} | R Documentation |
link{findThreshold}
The functions plotDistances
and plotMutinfo
are used to
visualize the distance threshold calculated by
findThreshold
in the context of pairwise distances among
objects in the reference set.
plotDistances(distances, D = NA, interval = NA, ylab = "distances", ...) plotMutinfo(breaks, D = NA, interval = NA, xlab = "distance", ylab = "mutual information", ...)
distances |
The |
breaks |
The |
D |
The distance threshold |
interval |
The range of values over which candidiate values of PMMI are evaluated. |
xlab |
Label the x axis of the plot. |
ylab |
Label the y axis of the plot. |

Additional arguments are passed to |
(plotMutinfo
)
plotDistances
produces a box-and-whisker plot contrasting within-
and between-group distances. plotMutinfo
produces a plot of
cutpoints vs mutual information scores.
Returns a lattice grid object.
