)Arguments
- data
A data frame.
- x
A character string specifying the column name of the data frame to plot for the x-axis.
- y
A character string of the column name to plot on the y-axis. A numeric column is expected. If NULL, the count of each x column will be used.
- label
Which column to use as the label. NULL means no label.
- split_by
The column(s) to split data by and plot separately.
- split_by_sep
The separator for multiple split_by columns. See
split_by- clockwise
A logical value to draw the pie chart clockwise or not.
- facet_by
A character string specifying the column name of the data frame to facet the plot. Otherwise, the data will be split by
split_byand generate multiple plots and combine them into one usingpatchwork::wrap_plots- facet_scales
Whether to scale the axes of facets. Default is "fixed" Other options are "free", "free_x", "free_y". See
ggplot2::facet_wrap- facet_ncol
A numeric value specifying the number of columns in the facet. When facet_by is a single column and facet_wrap is used.
- facet_nrow
A numeric value specifying the number of rows in the facet. When facet_by is a single column and facet_wrap is used.
- facet_byrow
A logical value indicating whether to fill the plots by row. Default is TRUE.
- theme
A character string or a theme class (i.e. ggplot2::theme_classic) specifying the theme to use. Default is "theme_this".
- theme_args
A list of arguments to pass to the theme function.
- palette
A character string specifying the palette to use.
- palcolor
A character string specifying the color to use in the palette.
- alpha
A numeric value specifying the transparency of the plot.
- aspect.ratio
A numeric value specifying the aspect ratio of the plot.
- legend.position
A character string specifying the position of the legend. if
waiver(), for single groups, the legend will be "none", otherwise "right".- legend.direction
A character string specifying the direction of the legend.
- title
A character string specifying the title of the plot. A function can be used to generate the title based on the default title. This is useful when split_by is used and the title needs to be dynamic.
- subtitle
A character string specifying the subtitle of the plot.
- xlab
A character string specifying the x-axis label.
- ylab
A character string specifying the y-axis label.
- keep_empty
A logical value indicating whether to keep empty groups. If FALSE, empty groups will be removed.
- combine
Whether to combine the plots into one when facet is FALSE. Default is TRUE.
- nrow
A numeric value specifying the number of rows in the facet.
- ncol
A numeric value specifying the number of columns in the facet.
- byrow
A logical value indicating whether to fill the plots by row.
- seed
The random seed to use. Default is 8525.
- ...

Examples
data <- data.frame(
x = c("A", "B", "C", "D", "E", "F", "G", "H"),
y = c(10, 8, 16, 4, 6, 12, 14, 2),
group = c("G1", "G1", "G2", "G2", "G3", "G3", "G4", "G4"),
facet = c("F1", "F2", "F3", "F4", "F1", "F2", "F3", "F4")
)
PieChart(data, x = "x", y = "y")
PieChart(data, x = "x", y = "y", clockwise = FALSE)
PieChart(data, x = "x", y = "y", label = "group")
PieChart(data, x = "x", y = "y", facet_by = "facet")
PieChart(data, x = "x", y = "y", split_by = "group")
# y from count
PieChart(data, x = "group")
