Description

ggplot type barplots representing frequencies for each vars.cat by partition level.

Usage

plot_frequency(
  data,
  partition.name,
  vars.cat,
  vars.cat.names = NULL,
  binary.simplify = TRUE,
  unclass.name = "Unclassified",
  include.unclass = FALSE
)

Arguments

data	The dataset.
partition.name	string. Name of the partition (in data). The partition variable should be a factor.
vars.cat	vector of strings. variables to plot (categorical only).
vars.cat.names	Optional. Names for displaying the categorical variables. (given in the same order than vars.cat)
binary.simplify	boolean. Should only the 1st level be kept for binary variables in vars.cat?
unclass.name	If applicable, name for the unclassified observations in the partition.
include.unclass	boolean, should boxplot be displayed for the unclassified or should they be excluded from the plot.

Value

ggplot object.

Examples

data(cancer, package = "survival")
cancer$status <- factor(cancer$status)
plot_frequency(data = cancer, partition.name = "status",
                  vars.cat = c("sex", "ph.ecog"))

## With unclassifieds
cancer$status.2 <- as.character(cancer$status)
cancer$status.2[sample(1:nrow(cancer), 30)] <- "Unclassif."
cancer$status.2 <- factor(cancer$status.2)
plot_frequency(data = cancer, partition.name = "status.2",
               vars.cat = c("sex", "ph.ecog"),
               unclass.name = "Unclassif.", include.unclass = TRUE)

## With unclassifieds (as NA)
cancer$status.3 <- cancer$status
cancer$status.3[sample(1:nrow(cancer), 30)] <- NA
plot_frequency(data = cancer, partition.name = "status.3",
               vars.cat = c("sex", "ph.ecog"),
               unclass.name = NA, include.unclass = TRUE)

plot_frequency(data = cancer, partition.name = "status.3",
               vars.cat = c("sex", "ph.ecog", "ph.karno"),
               binary.simplify = FALSE,
               unclass.name = NA, include.unclass = FALSE)
