SEIR_to_SIR_E: Convert SEIR to XYZ coordinates fixed in a tetrahedron

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

Description

Convert SEIR to XYZ coordinates fixed in a tetrahedron

Usage

SEIR_to_SIR_E(data, ternary_vars = c("S", "I", "R"), group_var = "E")

Arguments

data	data frame with the following columns t time step S Number of people in S E Number of people in E I Number of people in I R Number of people in R
ternary_vars	named vector of the three variables to use as the sides of the ternary plot. Can be of the form c("t", "l", "r", "f") or c(t,l,r,f).
group_var	name of the variable to use as the color/feature/grouping vector. column name that is associated with the time step. Can either be a string or a promisary symbol

Value

data frame with the transformed variables SEIR -> s, i, r, group variables

Examples

seir <- data.frame(t = 0:3,
S = c(90, 80, 70, 60),
E = c(0, 10, 10, 10),
I = c(10, 10, 10, 10),
R = c(0, 0, 10, 20))
seir_xyz <- SEIR_to_XYZ(seir)
head(seir_xyz)
