Arguments

df: A data frame containing the data to plot. For a single trace, provide columns for categories (theta) and values (r). For multiple traces, include a grouping column. The function automatically closes the radar polygon by adding the first point to the end.
theta: Character, name of the column to use for the angular categories (axes).
r: Character, name of the column to use for the radial values.
group: Optional character, name of the column to use for grouping multiple traces. If NULL, a single trace is plotted. Default: NULL.
colors: Optional character vector of hex colors for the traces. If named, values are matched to the group values; otherwise colours are recycled.
palette: Optional character vector of fallback colors used when colors is not supplied or missing values are present.
fill: Logical or character, whether to fill the area under each trace. Use "toself" to fill to the first point, or FALSE for no fill. Default: "toself".
line.width: Numeric, width of the trace lines in pixels. Default: 2.
line.dash: Character, line dash style. Options: "solid", "dot", "dash", "longdash", "dashdot", "longdashdot". Default: "solid".
marker.size: Numeric, size of the markers on the trace. Default: 5.
marker.symbol: Character, marker symbol. Options: "circle", "square", "diamond", "cross", "x", "triangle-up", etc. Default: "circle".
opacity: Numeric, opacity of the traces (0-1). Default: 0.6.
radial.visible: Logical, whether to show the radial axis. Default: TRUE.
radial.range: Optional numeric vector of length 2 specifying the range of the radial axis (e.g., c(0, 100)). If NULL, automatically determined. Default: NULL.
radial.showline: Logical, whether to show the radial axis line. Default: TRUE.
radial.linecolor: Character, hex color for the radial axis line. Default: "#444444".
radial.gridcolor: Character, hex color for the radial grid lines. Default: "#EEEEEE".
angular.direction: Character, direction of angular axis. Options: "clockwise" or "counterclockwise". Default: "clockwise".
angular.rotation: Numeric, rotation angle for the angular axis in degrees. Default: 90.
angular.gridcolor: Character, hex color for the angular grid lines. Default: "#EEEEEE".
show.legend: Logical, whether to display the legend. Default: TRUE.
legend.orientation: Character, legend orientation. Options: "h" (horizontal) or "v" (vertical). Default: "h".
legend.x: Numeric, horizontal legend position offset (0-1). Default: 0.5.
legend.y: Numeric, vertical legend position offset (-1 to 1). Default: -0.1.
legend.font.family: Character, font family for the legend text. Default: "Arial".
legend.font.size: Numeric, font size for the legend text. Default: 12.
legend.font.color: Character, hex color for the legend text. Default: "#000000".
title.text: Character, main plot title text. Default: "".
title.font.family: Character, font family for the title text. Default: "Arial".
title.font.size: Numeric, font size for the title text. Default: 18.
title.font.color: Character, hex color for the title text. Default: "#000000".
title.x: Numeric, horizontal position for the plot title (0-1). Default: 0.5.
bgcolor: Character, hex color for the plot background. Default: "#FFFFFF".
polar.bgcolor: Character, hex color for the polar area background. Default: "#FFFFFF".

# Single trace radar chart
# Note: Polygon is automatically closed by the function
skills <- data.frame(
    category = c("Speed", "Strength", "Defense", "Stamina"),
    value = c(8, 6, 7, 9)
)

radarPlot(
    df = skills,
    theta = "category",
    r = "value",
    title.text = "Player Stats"
)


# Multiple trace radar chart
# Note: Polygon is automatically closed for each trace
team_stats <- data.frame(
    category = rep(c("Speed", "Strength", "Defense", "Stamina"), 2),
    value = c(8, 6, 7, 9, 5, 9, 8, 6),
    player = rep(c("Player A", "Player B"), each = 4)
)

radarPlot(
    df = team_stats,
    theta = "category",
    r = "value",
    group = "player",
    title.text = "Team Comparison"
