Apply a function along edges within a pfc object

Features of the returned pfc will be the output of the function applied to the original features. Therefore the functionm provided must return a vector the same length of the input.

Usage

pf_edge_apply(x, fun, ...)

Arguments

x

A pfc object

fun

A function to apply to the edge vectors, which will be passed as the first argument. Must return a vector the same length and type as the input.

...

Any additional arguments to pass to fun

Value

A pfc object with the same structure as x but with features replaced with the output of fun

Examples

## average features of descendents of each edge as a pfc:
pf_edge_apply(pf_desc(pf_indexes(rpfc(100))), function(x) rep(mean(x), length(x)))
