getDistToCtr {shotGroups}

Distances to center for a set of points

Description

Calculates the distances of a set of points to their center.

Usage

getDistToCtr(xy)

## S3 method for class 'data.frame'
getDistToCtr(xy)

## Default S3 method:
getDistToCtr(xy)

Arguments

xy

either a numerical (n x p)-matrix with the coordinates of n points in p-dimensional space (1 row of coordinates per point), or a data frame with either the variables x, y or point.x, point.y.

Value

A numerical vector with the distances from each point to the center of the set.

Examples

# coordinates given by a suitable data frame
getDistToCtr(DFtalon)

# coordinates given by a matrix
## Not run: 
xy <- matrix(round(rnorm(20, 100, 15), 1), ncol=2)
getDistToCtr(xy)

## End(Not run)
