Delete an edge from a network edges data frame

Removes the row(s) from an edges data frame that match the given source, target, and interaction values. This is the programmatic counterpart of the interactive Ctrl+click / right-click edge deletion available in cytoscapeNetwork.

Usage

deleteEdgeFromNetwork(edges, source, target, interaction)

Arguments

edges

Data frame with at minimum columns source, target, and interaction.

source

Character. The source node identifier of the edge to remove.

target

Character. The target node identifier of the edge to remove.

interaction

Character. The interaction type of the edge to remove.

Value

The edges data frame with the matching row(s) removed.

Examples

edges <- data.frame(
  source      = c("TP53",  "MDM2",  "CDKN1A"),
  target      = c("MDM2",  "TP53",  "TP53"),
  interaction = c("Activation", "Inhibition", "Activation"),
  stringsAsFactors = FALSE
)
deleteEdgeFromNetwork(edges, "MDM2", "TP53", "Inhibition")
#>   source target interaction
#> 1   TP53   MDM2  Activation
#> 3 CDKN1A   TP53  Activation
