eccentricity_filter {mappeR} | R Documentation |
Compute eccentricity of data points
Description
Compute eccentricity of data points
Usage
eccentricity_filter(dists)
Arguments
dists |
A distance matrix associated to a data frame. |
Value
A vector of centrality measures, calcuated per data point as the sum of its distances to every other data point, divided by the number of points.
Examples
num_points = 5000
P.data = data.frame(
x = sapply(1:num_points, function(x)
sin(x) * 10) + rnorm(num_points, 0, 0.1),
y = sapply(1:num_points, function(x)
cos(x) ^ 2 * sin(x) * 10) + rnorm(num_points, 0, 0.1),
z = sapply(1:num_points, function(x)
10 * sin(x) ^ 2 * cos(x)) + rnorm(num_points, 0, 0.1)
)
P.dist = dist(P.data)
eccentricity = eccentricity_filter(P.dist)
