Draw multiple curves

Description

Draw multiple curves

Usage

draw_multiple_curves(
  ...,
  list = NULL,
  nrow = NULL,
  ncol = NULL,
  extend = TRUE,
  title = FALSE,
  closed = FALSE,
  padding = unit(0, "pt"),
  lwd = 4,
  col = NULL
)

Arguments

...	A list of 'sfc_sequence' objects or objects in its child classes, a list of ['grid::grob'] objects or a list of two-column coordinate matrices, i.e., all the forms that can represent curves in this package.
list	The list of curve object can also be directly specified as a "list" object.
nrow	Number of rows in the layout.
ncol	Number of columns in the layout.
extend	Whether to draw the entry and exit segments? It is only used when input is a list of 'sfc_sequence' objects.
title	Whether to add titles on each panel? The title is constructed in the form of 'initial_seed|expansion_codes', e.g. 'I|111'. The value can be a vector of user-defined strings.
closed	Whether the curves are closed? The value should be a logical vector. If it is 'TRUE', the last point is connected to the first point in the curve to form a closed curve. Length of 'closed' can be 1 or the number of curves.
padding	Space around each curve. The value should be a ['grid::unit'] object with length 1.
lwd	Line width with length 1.
col	Color for the segments with length 1. If the value is 'NULL', it uses the "Spectral" color palettes from the **RColorBrewer** package.

Details

This function is used for quick comparison on curves.

Value

No value is returned.

Examples

# for all forms of curves initialized by base pattern 'R', with rotation 0, and on level 3
draw_multiple_curves(
    sfc_2x2("R", "111"),
    sfc_2x2("R", "112"),
    sfc_2x2("R", "121"),
    sfc_2x2("R", "122"),
    sfc_2x2("R", "211"),
    sfc_2x2("R", "212"),
    sfc_2x2("R", "221"),
    sfc_2x2("R", "222"),
    nrow = 2, title = TRUE)

# simply a list of sequences
# note they only contain I/R/L, so the base patterns I/R/L are internally used
draw_multiple_curves(
    sfc_sequence("IIII"),
    sfc_sequence("RRRR"),
    sfc_sequence("RRLL"),
    nrow = 1
)
