[R-meta] using netmeta::netsplit()

I'm doing a network meta-analysis, using netmeta (v2.9-0). There are a
large number
of potential comparisons in my network.

My current plot displays all comparisons (too many) where
least one study contributes direct evidence.

ns1 <- netsplit(net1)
forest(ns1, show = "both")

My goal is to produce a forest plot showing only comparisons for which there
are at least 3 studies with direct evidence.

I think I want the 7 comparisons where k > 2

which(ns1$k > 2)

[1] 120 127 130 132 147 237 253

Thanks!
