PHom | R Documentation |
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.
PHom(x, dim_col = 1, birth_col = 2, death_col = 3)
