In mousetRajectory: Mouse Trajectory Analyses for Behavioural Scientists

Number of times a point is crossed

Description

Checks how often a number (relevant_point) is being crossed by an number sequence (numeric_vector).

Usage

point_crosses(numeric_vector, relevant_point = 0)

Arguments

numeric_vector	Numbers, ordered by their time of appearance.
relevant_point	Number which has to be crossed.

Details

The supplied vectors are assumed to be ordered by time.

Value

Number of times that numeric_vector crosses the relevant_point (0 to +Inf).
