subset_plot_df(x, sub_var, sub_val, keep_edges = c("all", "within", "none"))

Arguments

x: list of data.tables to subset (generated by igraph_plot_prep)
sub_var: variable to subset on; either a logical vector or a character string
sub_val: value to subset on
keep_edges: what edges to keep

if sub_var is a logical vector, it has to be of the same length as the number of rows in x$vertices. If sub_var is a string, it has to be equal a column in x$vertices.
