show_labels = "tophubs",

)
edgelist_int |
Data frame containing the edge list for the PPI network. First column is the protein 1 and second column is the protein 2. All other columns are interpreted as edge attributes. |
color_by |
How should nodes be colored? It must be either "community" or a 2-column data frame containing proteins in the first column and a custom annotation in the second column. If "community", a clustering algorithm will be applied. Default: "community". |
clustering_method |
igraph function to be used for community detection. Available functions are cluster_infomap, cluster_edge_betweenness, cluster_fast_greedy, cluster_walktrap, cluster_spinglass, cluster_leading_eigen, cluster_louvain, and cluster_label_prop. Default is cluster_infomap. |
show_labels |
Character indicating which nodes will be labeled. One of "all", "allhubs", "tophubs", or "none". |
top_n_hubs |
Number of top hubs to be labeled. It is only valid
if |
add_color_legend |
Logical indicating whether to add a color legend for nodes. Default: TRUE. |
curvature |
Numeric indicating the amount of curvature in edges. Negative values produce left-hand curves, positive values produce right-hand curves, and zero produces a straight line. Default: 0. |
interactive |
Logical indicating whether the network should be interactive or not. Default is FALSE. |
dim_interactive |
Numeric vector with width and height of window for interactive plotting. Default: c(600,600). |
A ggplot object.
