Base implementation of mutate
This implementation of mutate is slightly faster than
mutate at the expense
of the graph only being updated in the end. This means that graph algorithms
will not take changes happening during the mutate call into account.
columns to mutate
The order of speed increase are rather small and in the ~1 millisecond per
mutateed column order, so for regular use this should not be a choice. The
operations not supported by
mutate_as_tbl are e.g.
gr %>% activate(nodes) %>% mutate(weights = runif(10), degree = centrality_degree(weights))
weights will only be made available in the graph at the end of the
