Multiplex siteswap

Creates a multiplex siteswap object from a sequence in which square brackets group simultaneous throws from the same hand. For example, "[43]1" means the juggler throws heights 4 and 3 simultaneously on the first beat, then a single 1 on the second beat. Any slot without brackets is a single throw exactly as in vanilla siteswap.

Usage

multiplexSiteswap(sequence = character(0))

Arguments

sequence

A single character string of multiplex siteswap notation, e.g. "[43]1" or "[33]".

Value

A multiplexSiteswap S7 object.

Additional properties

@type

Always "multiplex" (read-only).

@slots

List of integer vectors, one element per time slot. Single-throw slots are length-1 vectors; multiplex slots have length > 1 (read-only).

@throws

Integer vector of all individual throw heights (flattened across all slots) (read-only).

@period

Number of time slots per cycle (read-only).

@symmetry

"symmetrical" when period is odd; "asymmetrical" when period is even (read-only).

@n_props

Total of all throw heights divided by the period — the number of props required. (Note: sum(throws) / period, not mean(throws).) (read-only).

@can_throw

TRUE if for every slot the number of props thrown equals the number of props landing (no conservation violation) (read-only).

@satisfies_average_theorem

TRUE if n_props is a whole number (read-only).

@valid

TRUE if both can_throw and satisfies_average_theorem are TRUE (read-only).

Examples

multiplexSiteswap("[43]1")
#> ✔ '[43]1' is valid multiplex siteswap
#> ℹ It uses 4 props
#> ℹ It is asymmetrical with period 2
multiplexSiteswap("[33]")
#> ✔ '[33]' is valid multiplex siteswap
#> ℹ It uses 6 props
#> ℹ It is symmetrical with period 1

s <- multiplexSiteswap("[43]1")
s@n_props
#> [1] 4
s@valid
#> [1] TRUE
