Adding normalized data to a metric graph.

[leninrafaelrierasegura]

Hello, I hope someone finds the following useful.

Assume below that graph is a metric graph and df is a data frame with normalized data (meaning df contains edge_number and distance_on_edge columns).

graph$add_observations(data = df, clear_obs = TRUE, normalized = FALSE)  #normalized = FALSE is the default option
a = graph$get_data()

graph$add_observations(data = df, clear_obs = TRUE, normalized = TRUE)
b = graph$get_data()

plot(a$.distance_on_edge)
lines(b$.distance_on_edge, col = "red")

Note that failing to specify normalized = TRUE changes the distance_on_edge column values.
