| barplot-methods {flexclust} | R Documentation |
Barplot of cluster centers or other cluster statistics.
## S4 method for signature 'kcca':
barplot(height, bycluster = TRUE, oneplot = TRUE,
data = NULL, FUN=colMeans, main = deparse(substitute(height)),
which = 1:height@k, names.arg = NULL,
oma=par("oma"), col=NULL, mcol="darkred", srt=45, ...)
## S4 method for signature 'kcca':
barchart(x, data, xlab="", strip.prefix="Cluster ",
col=NULL, mcol="darkred", panel=NULL, which=NULL, ...)
height, x |
An object of class "kcca". |
bycluster |
If TRUE, then each barplot shows one
cluster. If FALSE, then each barplot compares all cluster for
one input variable. |
oneplot |
If TRUE, all barplots are plotted together on
one page, else each plot is on a seperate page. |
data |
If not NULL, cluster membership is predicted for
the new data and used for the plots. By default the
values from the traing data are used. Ignored by the barchart
method. |
FUN |
The function to be applied to each cluster for calculating the bar heights. |
which |
For barplot index number of clusters for the plot,
for barchart index numbers or names of variables to plot. |
names.arg |
A vector of names to be plotted below each bar. |
main, oma, xlab, ... |
Graphical parameters. |
col |
Vector of colors for the clusters. |
mcol |
If not NULL, the value of
FUN for the complete data set is plotted over each bar as a
line segment with color mcol. |
srt |
Number between 0 and 90, rotation of the x-axis labels. |
strip.prefix |
Prefix string for the strips of the Trellis display. |
panel |
Panel function for barchart. |
