Build a network from odds ratio data. — build_or

Construct a tidygraph network from pairwise odds ratio or ROR data. Each node is a position (or isodecoder) and each edge represents a significant co-occurrence relationship. Requires the tidygraph and igraph packages.

Usage

build_or_network(data, value_col = "ror", min_weight = 0)

Arguments

data: A tibble with columns pos1, pos2, and a value column specified by value_col. Optionally includes p_adj.
value_col: Column name (string) for edge values. Default "ror".
min_weight: Minimum absolute value of value_col for an edge to be included. Default 0.

Value

A tbl_graph object with node metrics degree and betweenness, or NULL if no edges remain after filtering.

Examples

if (FALSE) { # \dontrun{
df <- tibble::tibble(
  pos1 = c("20", "34", "20"),
  pos2 = c("34", "58", "58"),
  ror = c(1.5, -0.8, 0.3)
)
build_or_network(df)
} # }
