Table themes

Additional theme constructors for use with geom_table.

Usage

ttheme_gtdefault(
  base_size = 10,
  base_colour = "black",
  base_family = "",
  parse = FALSE,
  padding = unit(c(0.8, 0.6), "char"),
  ...
)

ttheme_gtminimal(
  base_size = 10,
  base_colour = "black",
  base_family = "",
  parse = FALSE,
  padding = unit(c(0.5, 0.4), "char"),
  ...
)

ttheme_gtbw(
  base_size = 10,
  base_colour = "black",
  base_family = "",
  parse = FALSE,
  padding = unit(c(1, 0.6), "char"),
  ...
)

ttheme_gtplain(
  base_size = 10,
  base_colour = "black",
  base_family = "",
  parse = FALSE,
  padding = unit(c(0.8, 0.6), "char"),
  ...
)

ttheme_gtdark(
  base_size = 10,
  base_colour = "grey90",
  base_family = "",
  parse = FALSE,
  padding = unit(c(0.8, 0.6), "char"),
  ...
)

ttheme_gtlight(
  base_size = 10,
  base_colour = "grey10",
  base_family = "",
  parse = FALSE,
  padding = unit(c(0.8, 0.6), "char"),
  ...
)

ttheme_gtsimple(
  base_size = 10,
  base_colour = "grey10",
  base_family = "",
  parse = FALSE,
  padding = unit(c(0.5, 0.4), "char"),
  ...
)

ttheme_gtstripes(
  base_size = 10,
  base_colour = "grey10",
  base_family = "",
  parse = FALSE,
  padding = unit(c(0.8, 0.6), "char"),
  ...
)

Arguments

base_size

numeric, default font size.

base_colour

default font colour.

base_family

default font family.

parse

logical, default behaviour for parsing text as plotmath.

padding

length-2 unit vector specifying the horizontal and vertical padding of text within each cell.

...

further arguments to control the gtable.

Value

A list object that can be used as ttheme in the construction of tables with functions from package 'gridExtra'.

Details

Depending on the theme, the base_colour, which is mapped to the colour aesthetic if present, is applied to only the text elements, or to the text elements and rules. The difference is exemplified below.

Note

These theme constructors are wrappers on gridExtra::ttheme_default() and gridExtra::ttheme_minimal(). They can also be used with grid.table if desired.

Examples

library(dplyr)
library(tibble)

mtcars %>%
  group_by(cyl) %>%
  summarize(wt = mean(wt), mpg = mean(mpg)) %>%
  ungroup() %>%
  mutate(wt = sprintf("%.2f", wt),
         mpg = sprintf("%.1f", mpg)) -> tb

df <- tibble(x = 5.45, y = 34, tb = list(tb))

# Same as the default theme constructor

  geom_point() +
  geom_table(data = df, aes(x = x, y = y, label = tb),
             table.theme = ttheme_gtdefault) +
  theme_classic()


# Minimal theme constructor

# Default colour of theme superceded by aesthetic constant
