pca_centralities {CINNA}R Documentation

Ranking centrality measure based on contributions

Description

This function demonstrates ranks of centrality measures in order of information levels.

Usage

pca_centralities(
  x,
  scale.unit = TRUE,
  cut.off = 80,
  ncp = 5,
  graph = FALSE,
  axes = c(1, 2)
)

Arguments

x

a list containg the computed centrality values

scale.unit

a boolean constant, whether data should be scaled to unit variance(default=TRUE)

cut.off

The intensity that must be exceeded in cumulative percentage of variance of eigen values.(default=80)

ncp

number of dimensions in final results (default=5)

graph

a boolean constant, whether the graph shoul be displayed

axes

a length 2 vector describing the number of components to plot(default=c(1,2))

Details

This function represents centralities in the ranking list based on variable contribution to make principal components. PCA is a method for drawing out important variables from a data set. It helps user to reduced the dimensions in high dimensional data. It is more common to use for more than 3 dimensional datasets.

Value

a plot illustrating significant centralities in the order of contribution
