igraph object.

- attr
edge attribute name that encodes positve ("P"), negative ("N") and ambivalent ("A") ties.

## Value

counts for all complex triangle types

## Examples

```
library(igraph)
g <- graph.full(4)
E(g)$type <- c("P","N","A","A","P","N")
count_complex_triangles(g,attr = "type")
#> PPP PPN PNN NNN PPA PNA NNA PAA NAA AAA
#> 0 0 0 0 1 2 1 0 0 0
