create_delta_ball_structure: create the delta ball associated with points

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

Description

create the delta ball associated with points

Usage

create_delta_ball_structure(
  data_points,
  data_columns = NULL,
  .lower_simplex_project = TRUE
)

Arguments

data_points	points to create the delta ball structure from
data_columns	columns of data.frame that relate to the point's coordinates in euclidean space. This should be at least 3 columns (else it doesn't really make sense to use this function). The input should look like something like c(S,I,R) or c("S", "I", "R"). If the input is NULL this function will treat this like dplyr::everything().
.lower_simplex_project	boolean, if data points should be projected to a simplex and then to the lower dimensional simplex (for this package, this should always be done)

Value

a delta_ball_structure object, that is a data frame similar to data_points (but with out data_columns columns) and distinct points. This object also has an delta attribute which contains the delta defining the delta ball.

Examples

library(dplyr)
delta_ball_cb <- EpiCompare::pomp_df %>%
  filter(.id <= 10) %>%
  arrange(time) %>% # just to be safe
  select(-time, -H, -cases) %>%
  group_by(.id) %>%
  grab_top_depth_filaments(conf_level = .9) %>%
  create_delta_ball_structure() #data_columns = c(S,I,R)
