Plot the Component CDF using plotly

Description

Plot the components' CDF via the posterior probabilities using plotly.

Usage

plotly_compCDF(data, weights, x=seq(min(data, na.rm=TRUE), max(data, na.rm=TRUE), 
               len=250), comp=1:NCOL(weights), makeplot=TRUE,
               cex = 3, width = 3,
               legend.text = "Composition", legend.text.size = 15, legend.size = 15,
               title = "Empirical CDF", title.x = 0.5, title.y = 0.95, title.size = 15,
               xlab = "Data", xlab.size = 15, xtick.size = 15,
               ylab = "Probability", ylab.size = 15, ytick.size = 15,
               col.comp = NULL) 

Arguments

data	A matrix containing the raw data. Rows are subjects and columns are repeated measurements.
weights	The weights to compute the empirical CDF; however, most of time they are the posterior probabilities.
x	The points at which the CDFs are to be evaluated.
comp	The mixture components for which CDFs are desired.
makeplot	Logical: Should a plot be produced as a side effect?
cex	Size of markers.
width	Line width.
title	Text of the main title.
title.size	Size of the main title.
title.x	Horsizontal position of the main title.
title.y	Vertical posotion of the main title.
xlab	Label of X-axis.
xlab.size	Size of the lable of X-axis.
xtick.size	Size of tick lables of X-axis.
ylab	Label of Y-axis.
ylab.size	Size of the lable of Y-axis.
ytick.size	Size of tick lables of Y-axis.
legend.text	Title of legend.
legend.text.size	Size of the legend title.
legend.size	Size of legend.
col.comp	Color of compositions. Number of color specified needs to be consistent with number of compositions.

Details

When makeplot is TRUE, a line plot is produced of the CDFs evaluated at x. The plot is not a step function plot; the points (x, CDF(x)) are simply joined by line segments.

Value

A matrix with length(comp) rows and length(x) columns in which each row gives the CDF evaluated at each point of x.

Examples

## The sulfur content of the coal seams in Texas
set.seed(100)
A <- c(1.51, 1.92, 1.08, 2.04, 2.14, 1.76, 1.17)
B <- c(1.69, 0.64, .9, 1.41, 1.01, .84, 1.28, 1.59)
C <- c(1.56, 1.22, 1.32, 1.39, 1.33, 1.54, 1.04, 2.25, 1.49)
D <- c(1.3, .75, 1.26, .69, .62, .9, 1.2, .32)
E <- c(.73, .8, .9, 1.24, .82, .72, .57, 1.18, .54, 1.3)
dis.coal <- makemultdata(A, B, C, D, E,
                         cuts = median(c(A, B, C, D, E)))
temp <- multmixEM(dis.coal)
## Now plot the components' CDF via the posterior probabilities
plotly_compCDF(dis.coal$x, temp$posterior, xlab="Sulfur")
