ggradar: Create radar charts using ggplot2

Description

This package exports the functionality of ggplot2 to create radar charts.

Usage

ggradar(
  plot.data,
  base.size = 15,
  font.radar = "sans",
  values.radar = c("0%", "50%", "100%"),
  axis.labels = colnames(plot.data)[-1],
  grid.min = 0,
  grid.mid = 0.5,
  grid.max = 1,
  centre.y = grid.min - ((1/9) * (grid.max - grid.min)),
  plot.extent.x.sf = 1,
  plot.extent.y.sf = 1.2,
  x.centre.range = 0.02 * (grid.max - centre.y),
  label.centre.y = FALSE,
  grid.line.width = 0.5,
  gridline.min.linetype = "longdash",
  gridline.mid.linetype = "longdash",
  gridline.max.linetype = "longdash",
  gridline.min.colour = "grey",
  gridline.mid.colour = "#007A87",
  gridline.max.colour = "grey",
  grid.label.size = 6,
  gridline.label.offset = -0.1 * (grid.max - centre.y),
  label.gridline.min = TRUE,
  label.gridline.mid = TRUE,
  label.gridline.max = TRUE,
  axis.label.offset = 1.15,
  axis.label.size = 5,
  axis.line.colour = "grey",
  group.line.width = 1.5,
  group.point.size = 6,
  group.colours = NULL,
  background.circle.colour = "#D7D6D1",
  background.circle.transparency = 0.2,
  plot.legend = if (nrow(plot.data) > 1) TRUE else FALSE,
  legend.title = "",
  plot.title = "",
  legend.text.size = 14,
  legend.position = "left",
  fill = FALSE,
  fill.alpha = 0.5
)
