# DistanceCheck: Check if Two Points Lie Within some Distance in All... In SimilarityMeasures: Trajectory Similarity Measures

## Description

A function to check whether two points lie within some distance in every dimension.

## Usage

 `1` ```DistanceCheck(point1, point2, dist, dimensions=length(point1)) ```

## Arguments

 `point1` An n dimensional vector representing point1. `point2` An n dimensional vector representing point2. `dist` A floating point number representing the maximum distance in each dimension allowed for points to be considered equivalent. `dimensions` An integer representing the number of dimensions being checked. This defaults to the length of the first vector.

## Value

A boolean value is returned. The value is true if the points are within the distance in every dimension and false if not.

## Examples

 ```1 2 3 4 5 6 7``` ```# Creating two points. point1 <- c(0, 2, 4, 6) point2 <- c(0, 1, 2, 3) # Running the check with distances 1 and 3 in 4 dimensions. DistanceCheck(point1, point2, 1, 4) DistanceCheck(point1, point2, 3, 4) ```
