set_var_bounds: Set bounds of fuzzy subsets

In ngort01/fuzzyMM: Map Matching Using Fuzzy Logic

Description

This function allows to set the bounds for the fuzzy subsets to adjust the membership functions to your needs. These bounds represent the x values at which the sigmoidal membership functions reach ~0 or ~1 respectivly(e.g. “speed is high” ranges from 3 to 6 m/s).

Usage

set_var_bounds(name = c("speed_high", "speed_low", "speed_zero", "HE_small",
  "HE_large", "PD_short", "PD_long", "HDOP_good", "HDOP_bad",
  "alpha_low, alpha_high", "beta_low", "beta_high", "delta_dist_neg",
  "delta_dist_pos", "HI_small", "HI_large", "HI_180", "connectivity_direct",
  "connectivity_indirect", "dist_err_small", "dist_err_large"),
  bounds = "numeric", default = FALSE)

Arguments

name	name of the variable which bounds should be changed.
bounds	numeric vector containing the lower and upper bound.
default	logical, restores the default bounds if true.
