PHom: Persistence Data Container

Description

PHom() creates instances of PHom objects, which are convenient containers for persistence data. Generally, data frame (or similar) objects are used to create PHom instances with users specifying which columns contain dimension, birth, and death details for each feature.

Usage

PHom(x, dim_col = 1, birth_col = 2, death_col = 3)

Value

PHom instance

Arguments

x

object used to create PHom instance

dim_col

either integer representing column index for feature dimension data or character representing column name

birth_col

either integer representing column index for feature birth data or character representing column name

death_col

either integer representing column index for feature death data or character representing column name

Examples

# construct data frame with valid persistence data
df <- data.frame(dimension = c(0, 0, 1, 1, 1, 2),
                 birth = rnorm(6),
                 death = rnorm(6, mean = 15))

# create `PHom` instance and print
df_phom <- PHom(df)
df_phom

# print feature details to confirm accuracy
print.data.frame(df_phom)
