fun_secants: Add secants

In JohnCoene/funplot: A Powerful Library Built on Top of 'd3.js' Whose Purpose Is to Render Functions With Little Configuration

Description

Add secants to the previously added function.

Usage

fun_secants(p, x0, x1 = NULL, mouse = FALSE)

Arguments

p	Plot as initialised by funplot.
x0, x1	See details.
mouse	Update secant on mouse move.

Details

If a data object has a secants, then each object will be used to compute secant lines between two points belonging to the function, additionally if updateOnMouseMove is a property set to true in the object then (x_{0},f(x_{1})) will be used as an anchored point and (x_{0},f(x_{1})) will be computed dynamically based on the mouse abscissa.

Values for secants list:

• x0 the abscissa of the first point

• x1 (optional if updateOnMouseMove is set) the abscissa of the second point

• mouse (optional) if set to TRUE x1 will be computed dynamically based on the current position of the mouse.

Examples

funplot() %>%
  fun_add("x^2") %>%
  fun_secants(x0 = 5, mouse = TRUE) %>%
  fun_secants(x0 = 2, x1 = 3)
