show_abcd: Draw ABCD linear dynamics phase plane flow

In dtkaplan/Znotes:

Draw ABCD linear dynamics phase plane flow

Description

Draw ABCD linear dynamics phase plane flow

Usage

show_abcd(
  a,
  b,
  c,
  d,
  which = c("both", "x", "y"),
  show_sign = FALSE,
  pow = 0.3
)

Arguments

a,	b, c, d: Four components of the dynamics matrix.
which	Which variable(s) to show the positive side of the nullcline in color
show_sign	When TRUE, show the flow vectors all the same length
pow	Exponent to use for display length versus actual length of a flow vector

Details

pow can be used to make the very short flow vectors near the origin look bigger. Default is 0.3.

Examples

Znotes::show_abcd(-.5, -1, 1, .7)
