scale_fill_selection

ggplot2 helpers

Description

Add scale_fill_selection() or scale_color_selection to a ggplot to customize the scale for fill or color, respectively, for linked brushing. Use selection_factor to turn logical vectors representing selection, to a factor with the levels ordered for use with ggplot2 bar stacking.

Usage

scale_fill_selection(color_false, color_true)

scale_color_selection(color_false, color_true)

selection_factor(
  x,
  na.replace = c(FALSE, NA, TRUE),
  reverse = packageVersion("ggplot2") < "2.2.0"
)

Arguments

`color_false`	The color that should be mapped to unselected rows
`color_true`	The color that should be mapped to selected rows
`x`	Either a data frame with a `selected_` column, or, a logical vector indicating which rows are selected
`na.replace`	The value to use to replace `NA` values; choose either `FALSE`, `NA`, or `TRUE` based on how you want values to be treated when no selection is active
`reverse`	Whether the factor level order should be `c(FALSE, TRUE)` (normal) or `c(TRUE, FALSE)` (reverse). The former is required for ggplot2 2.2.0+, the latter for earlier versions.

Examples

## Not run: 
sd <- SharedData$new(iris)
renderPlot({
  df <- sd$data(withSelection = TRUE, withFilter = TRUE)
  ggplot(df, aes(Sepal.Length, Sepal.Width,
    color = selection_factor(df))) +
    geom_point() +
    scale_color_selection("#444444", "skyblue1")
})
