| hist,flowClust-method {flowClust} | R Documentation |
This method generates a one-dimensional density plot for the specified dimension (variable) based on the robust model-based clustering results. A histogram of the actual data or cluster assignment is optional for display.
## S4 method for signature 'flowClust':
hist(x, data=NULL, subset=1, include=1:(x@K), histogram=TRUE,
labels=TRUE, xlim=NULL, ylim=NULL, xlab=NULL, ylab="Density",
main=NULL, breaks=50, col=NULL, pch=20, cex=0.6, ...)
x |
Object returned from flowClust or from running filter on a flowFrame object. |
data |
A numeric vector, matrix, data frame of observations, or object of class flowFrame. This is the object on which flowClust or filter was performed. |
subset |
An integer indicating which variable is selected for the plot. Alternatively, a character string containing the name of the variable is allowed if x@varNames is not NULL. |
include |
A numeric vector specifying which clusters are shown on the plot. By default, all clusters are included. |
histogram |
A logical value indicating whether a histogram of the actual data is made in addition to the density plot or not. |
labels |
A logical value indicating whether information about cluster assignment is shown or not. |
xlim |
The range of x-values for the plot. If NULL, the data range will be used. |
ylim |
The range of y-values for the plot. If NULL, an optimal range will be determined automatically. |
xlab, ylab |
Labels for the x- and y-axes respectively. |
main |
Title of the plot. |
breaks |
Content to be passed to the breaks argument of the generic hist function, if histogram is TRUE. Default is 50, meaning that 50 vertical bars with equal binwidths will be drawn. |
col |
Colors of the plotting characters displaying the cluster assignment (if labels is TRUE). If NULL (default), it will be determined automatically. |
pch |
Plotting character used to show the cluster assignment. |
cex |
Size of the plotting character showing the cluster assignment. |
... |
Further arguments passed to curve (and also hist if histogram is TRUE). |
