ggally_table {GGally}R Documentation

Display a table of the number of observations

Description

Plot the number of observations as a table. Other statistics computed by stat_cross could be used (see examples).

Usage

ggally_table(
  data,
  mapping,
  keep.zero.cells = FALSE,
  ...,
  geom_tile_args = NULL
)

ggally_tableDiag(
  data,
  mapping,
  keep.zero.cells = FALSE,
  ...,
  geom_tile_args = NULL
)

Arguments

data

data set using

mapping

aesthetics being used

keep.zero.cells

If TRUE, display cells with no observation.

...

other arguments passed to geom_text(...)

geom_tile_args

other arguments passed to geom_tile(...)

Note

The colour aesthetic is taken into account only if equal to x or y.

Examples

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

data(tips)
p_(ggally_table(tips, mapping = aes(x = smoker, y = sex)))
p_(ggally_table(tips, mapping = aes(x = day, y = time)))
p_(ggally_table(tips, mapping = aes(x = smoker, y = sex, colour = smoker)))

# colour is kept only if equal to x or y
p_(ggally_table(tips, mapping = aes(x = smoker, y = sex, colour = day)))

# diagonal version
p_(ggally_tableDiag(tips, mapping = aes(x = smoker)))

# custom label size and color
p_(ggally_table(tips, mapping = aes(x = smoker, y = sex), size = 16, color = "red"))

# display column proportions
p_(ggally_table(
  tips,
  mapping = aes(x = day, y = sex, label = scales::percent(after_stat(col.prop)))
))

# draw table cells
p_(ggally_table(
  tips,
  mapping = aes(x = smoker, y = sex),
  geom_tile_args = list(colour = "black", fill = "white")
))

# Use standardized residuals to fill table cells
p_(ggally_table(
  as.data.frame(Titanic),
  mapping = aes(
    x = Class, y = Survived, weight = Freq,
    fill = after_stat(std.resid),
    label = scales::percent(after_stat(col.prop), accuracy = .1)
  ),
  geom_tile_args = list(colour = "black")
) +
  scale_fill_steps2(breaks = c(-3, -2, 2, 3), show.limits = TRUE))
