Replace feature with edge index in a pfc

This is similar to base R's col() function, it returns a pfc with features that are just the index of the edge. Useful for complex indexing procedures

Usage

pf_indexes(x)

Arguments

x

A pfc object

Value

A new pfc with the same structure as x, but with the features of each edge equal to the edge index (the column number in the sparse matrix representation)

Examples

pf_indexes(rpfc(100))
