as.PHom: Convert to PHom Object

In rrrlw/ripserr: Calculate Persistent Homology with Ripser-Based Engines

Convert to PHom Object

Description

Converts valid objects to PHom instances.

Usage

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

Arguments

x	object being converted to 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

Value

PHom instance

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))

# convert to `PHom` instance and print
df_phom <- as.PHom(df)
df_phom

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