Convert sample family data.frames to igraphlight objects

Connections among samples and their ancestors are recorded in sample_family data.frames. as_igraph() converts them to igraphlite objects.

Usage

# S3 method for class 'sample_family'
as_igraph(x, ...)

Arguments

x

A sample_family data.frame in the output of tekka().

...

Additional arguments passed to igraphlite::graph_from_data_frame().

Examples

set.seed(666)
result = tekka("-y25 -l2 --sa 2,2 --sj 2,2")
samples = result$sample_family[[1L]]
as_igraph(samples)
