Plot pathways on a time axis — plot.dynet

One row per route, drawn along real time: a point at each vertex placed at the moment the route reaches it, joined by a segment. The horizontal gap between two points is the waiting time at that vertex, so the drawing is time-respecting in the way a bar of a route string is not – a route that waits is visibly slower than one that does not, and where routes arrive relative to each other is read off the axis.

Usage

# S3 method for class 'dynet_pathways'
plot(x, top = 12L, labels = TRUE, base_size = 12, ...)

Arguments

x: A dynet_pathways result.
top: Number of routes to draw, most frequent first. Defaults to twelve, which keeps the vertex labels legible.
labels: Whether to name the vertex at each step. TRUE by default; turn it off for a dense figure where the shape is the point.
base_size: Base font size, as in ggplot2::theme_minimal(). Defaults to twelve.
...: Ignored.

Value

A ggplot object. A top, labels or base_size that is not one valid value raises dynet_bad_input.

Details

Routes are ordered by frequency, most used at the top, with the count and share to the right of each. Fill marks the endpoint, which the row already names, so colour never carries a distinction alone.

Examples

dn <- dynet(school_contacts)
routes <- pathways(dn, from = "Ana")
plot(routes)
