Cross-tabulated tables of discrete variables

ggtable is a variant of ggduo for quick cross-tabulated tables of discrete variables.

ggtable(
  data,
  columnsX = 1:ncol(data),
  columnsY = 1:ncol(data),
  cells = c("observed", "prop", "row.prop", "col.prop", "expected", "resid", "std.resid"),
  fill = c("none", "std.resid", "resid"),
  mapping = NULL,
  ...
)

Arguments

data: dataset to be used, can have both categorical and numerical variables
columnsX, columnsY: names or positions of which columns are used to make plots. Defaults to all columns.
cells: Which statistic should be displayed in table cells?
fill: Which statistic should be used for filling table cells?
mapping: additional aesthetic to be used, for example to indicate weights (see examples)
...: additional arguments passed to ggduo (see examples)

Examples

# small function to display plots only if it's interactive
p_ <- GGally::print_if_interactive

data(tips)
p_(ggtable(tips, "smoker", c("day", "time", "sex")))


# displaying row proportions
p_(ggtable(tips, "smoker", c("day", "time", "sex"), cells = "row.prop"))


# filling cells with standardized residuals
p_(ggtable(tips, "smoker", c("day", "time", "sex"), fill = "std.resid", legend = 1))


# if continuous variables are provided, just displaying some summary statistics
p_(ggtable(tips, c("smoker", "total_bill"), c("day", "time", "sex", "tip")))


# specifying weights
d <- as.data.frame(Titanic)
p_(ggtable(
  d,
  "Survived",
  c("Class", "Sex", "Age"),
  mapping = aes(weight = Freq),
  cells = "row.prop",
  fill = "std.resid"
))
