plot.remify

several plots that describe the network of relational events, both for directed and undirected relational events.

Usage

# S3 method for remify
plot(
  x,
  which = c(1:5),
  breaks = 15L,
  palette = "Purples",
  n_intervals = 4L,
  rev = TRUE,
  actors = attr(x, "dictionary")$actors$actorName,
  pch.degree = 20,
  igraph.edge.color = "#4daa89",
  igraph.vertex.color = "#5AAFC8",
  ...
)

Arguments

x

is a remify object.

which

one or more numbers between 1 and 5. Plots described in order: (1) distribution of the inter-event times (histogram), (2) tile plot titled 'activity plot', with in-degree and out-degree activity line plots on the sides (or total-degree on the top side if the network is undirected). Tiles' color is scaled based on the count of the directed (or undirected) dyad, (3) for directed networks two plots of normalized out-degree and in-degree (values ranging in [0,1]) over a set of n_intervals (evenly spaced). For undirected networks one plot of normalized total-degree over the n_intervals (also here values ranging in [0,1]). The normalization is calculated in each interval as the (degree-min(degree))/(max(degree)-min(degree))) for each actor considering minimum and maximum degree (in-, out- or total-) observed in the interval (opacity and size of the points is proportional to the normalized measure), (4) four plots: (i) number of events (# events) per time interval, (ii) proportion of observed dyads (# dyads / x$D) per time interval, (iii) and (iv) (for directed network only) proportion of active senders and receivers per time interval (calculated as # senders/ x$N and # receiver/x$N per interval), (5) two networks: (i) network of events where edges are considered undirected (edges' opacity is proportional to the counts of the undirected events, vertices' opacity is proportional to the total-degree of the actors), (ii) visualization of directed network (edges' opacity is proportional to the counts of the directed events, vertices' opacity is proportional to the in-degree of the actors).

breaks

default is 15L and it describes the number of cells of the histogram plot for the inter-event times. It can be specified in the same way as the argument used by the function graphics::hist() (see ?graphics::hist for more details).

palette

a palette from grDevices::hcl.pals() (default is the "Purples" palette).

n_intervals

number of time intervals for time plots (default is 10).

rev

default is TRUE (reverse order of the color specified in palette)

actors

default is the set of actors in the network (see attr(x,"dictionary")[["actors"]]). The user can specify a subset of actors on which to run the descriptive plots. If the set contains more than 50 actors, then the function will select the 50 most active actors from the set provided.

pch.degree

default is 20. Shape of the points for the degree plots (in-degree, out-degree, total-degree).

igraph.edge.color

color of the edges in visualization of the network with vertices and nodes. The user can specify the hex value of a color, the color name or use the functiongrDevices::rgb() which returns the hex value.

igraph.vertex.color

color of the vertices in visualization of the network with vertices and nodes. The user can specify the hex value of a color, the color name or use the function grDevices::rgb() which returns the hex value.

other graphical parameters

Value

no return value, called for plotting descriptives on the relational event history data.
