Compute E_max (maximum expected displacement) from pre‑computed vectors
Usage
compute_emax(mean_cos_turning, mean_step_length = NULL, dimensional = FALSE)
Arguments
- mean_cos_turning
Numeric vector of mean cosine of turning angles.
- mean_step_length
Numeric vector of mean step lengths (required if dimensional = TRUE).
- dimensional
Logical. If TRUE, returns E_max in spatial units;
otherwise returns the dimensionless ratio.
Value
Numeric vector of E_max values (same length as mean_cos_turning),
with NA for invalid inputs and Inf for perfectly straight paths.
Examples
compute_emax(mean_cos_turning = 0.8)
#> [1] 3
# The dimensional form also accounts for step length
compute_emax(0.8, mean_step_length = 1.2, dimensional = TRUE)
#> [1] 3.6
