Plot Frequencies of Level Combinations

Source: R/plot_level_frequencies.R

For combinations of columns c1 and c2 in data, ggplot-objects are generated each of which shows the number (relative = FALSE) or percentage (relative = TRUE) of the different possible combinations of values in c1, and c2. The combinations of column names are created from the permutation of column names given in vars_1 and vars_2, respectively.

plotLevelFrequencies(data, vars_1 = NULL, vars_2 = NULL,
  relative = TRUE)

Arguments

data

data frame
vars_1

first vector of column names
vars_2

second vector of column names
relative

if TRUE (default)

Value

list of objects of class "ggplot"

Examples

data <- data.frame(
  fruit = c("apple", "cherry", "apple", "banana", "cherry"),
  colour = c("green", "red", "red", "yellow", "green"),
  size = c("small", "small", "big", "small", "big")
)
