Value

No return value, called for visualization

Arguments

df

dataset processed with data_preparation or in the designated form

pcol

color of the line of the polygon

pfcol

color to fill the area of the polygon, default is NULL.

axistype

type of axes. 0:no axis label. 1:center axis label only. 2:around-the-chart label only. 3:both center and around-the-chart labels. Default is 0.

seg

number of segments for each axis, default is 4.

pty

point symbol, default is 16. 32 means not printing the points.

plty

line types for plot data, default is 1:6

plwd

line widths for plot data, default is 1

pdensity

filling density of polygons, default is NULL

pangle

angles of lines used as filling polygons, default is 45

cglty

line type for radar grids, default is 1.4

cglwd

line width for radar grids, default is 0.1

cglcol

line color for radar grids, default is #000000

axislabcol

color of axis label and numbers, default is #808080

title

title of the chart, default is blank

na.itp

logical. If true, items with NA values are interpolated from nearest neighbor items and connect them. If false, items with NA are treated as the origin. Default is TRUE.

centerzero

logical. If true, this function draws charts with scaling originated from (0,0). If false, charts originated from (1/segments). Default is TRUE.

vlabels

character vector for the names for variables, default is NULL

vlcex

font size magnification for vlabels, default is 1

caxislabels

center axis labels, default is seq(0,1,by = 0.25)

calcex

font size magnification for caxislabels, default is NULL

paxislabels

around-the-chart labels, default is NULL

palcex

font size magnification for paxislabels, default is NULL

Details

This is the main function in the R package that takes a list of data frame(s) and constructs an origami plot. The function plots the main axes of the radar chart as solid lines and marks the score of each variable on these axes with a filled circle. Additionally, it plots auxiliary axes as dashed lines at equal distances between each neighboring pair of primary axes with auxiliary points generated from data_preparation. Finally, the function connects all the points in order and obtain a connected region that resembles an origami star. Through this method, we successfully address the challenge of axis order affecting the area of the connected region in radar plots. The plot generated using ‘origami_plot’ benefit in that the area of the connected region within the origami plot remains consistent regardless of axis sequence.

Examples

data(sucra)
df_list <- data_preparation(sucra, min_value = 0.15)
origami_plot(df=df_list[[1]], pcol = rgb(0.2,0.5,0.5,1),
pfcol = rgb(0.2,0.5,0.5,0.1),axistype=1, pty = 32)
