Display a table of the number of observations

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

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.
