to_lower_simplex: move df to simplex representation

In skgallagher/EpiCompare: A Pipeline to Analyze and Compare Infectious Disease Epidemics

Description

This function takes a data.frame, moves it to unit simplex representation and then projects the points onto a lower representation space (using A).

Usage

to_lower_simplex(df, A = NULL)

Arguments

df	an n x p data.frame, all scalar columns
A	default is NULL, if so, we create A from simplex_project_mat

Value

updated dat.frame (n x k), where k should be p-1, but that's assuming A is made from simplex_project_mat

Examples

center <- data.frame(x = 1, y = 1, z = 1)
to_lower_simplex(center) # 0,0 # center

side <- data.frame(x = 1, y = 0, z =0)
to_lower_simplex(side) #(1,0)
