Plot assignment distributions

Description

Plot individual assignment probability distributions.

Usage

plotAssignments(
  probs,
  orig,
  type = NULL,
  ylab = NULL,
  freq.sep.line = TRUE,
  plot = TRUE
)

Arguments

probs	matrix or data.frame of individual assignment probabilities. Each column represents probability of assignment to that group and rows sum to one.
orig	vector of original group assignments
type	either area for stacked continuous area plot or bar for discrete stacked bar chart. The latter is prefered for small numbers of cases. If not specified, a bar chart will be used if all classes have <= 30 cases.
ylab	label for y-axis
freq.sep.line	put frequency of original group on second line in facet label? If FALSE, labels are single line. If NULL frequencies will not be included in labels.
plot	display the plot?

Value

the ggplot object is invisibly returned.

Examples

n <- 40
probs <- abs(c(rnorm(n, 80, 10), rnorm(n, 20, 10)))
probs <- (probs - min(probs)) / max(probs)
probs <- cbind(probs, 1 - probs)
colnames(probs) <- NULL
orig <- rep(c("Group.1", "Group.2"), each = n)

plotAssignments(probs, orig)

n <- 15
probs <- abs(c(rnorm(n, 80, 10), rnorm(n, 20, 10)))
probs <- (probs - min(probs)) / max(probs)
probs <- cbind(probs, 1 - probs)
colnames(probs) <- NULL
orig <- rep(c("Group.1", "Group.2"), each = n)

plotAssignments(probs, orig)
