Simple Line-Splitting Function

Description

'rcl.s' is used to find the input values under which a user-supplied function outputs a specified value by searching on a user-specified interval

Usage

rcl.s(FNS, ..., y_goal = .Machine$double.neg.eps^0.5, 
      x_lo = .Machine$double.neg.eps^0.25, 
      x_up = 1 - .Machine$double.neg.eps^0.25, 
      s_tol = .Machine$double.neg.eps^0.5, 
      s_mit = 1e2, trace_plot = FALSE)

Arguments

FNS	user-supplied function. Must input only a single number and output only a single number.
...	arguments passed to the user-supplied function.
y_goal	the goal output value.
x_lo	the lower endpoint of the interval for the input value.
x_up	the upper endpoint of the interval for the input value.
s_tol	tolerance value for convergence diagnostic. If the absolute value of the difference between the output value at the current iteration and the goal output value is less than this tolerance value the algorithm terminates successfully.
s_mit	maximum number of iterations.
trace_plot	logical: return also a traceplot?

Value

A dataframe with the following columns:

pi	input values.
lr	output values.

If trace_plot = TRUE also a plot.
