Plot a dsem as a graph of its arrows

One node per series, and a further node lag(series, k) for a source read k years back. A path is a solid edge, blue when its estimate is positive and red when negative; an sd line is a grey loop on its own node and a covariance a grey dashed line with no head. Nodes are laid out in layers, in base graphics.

Usage

plot_dsem_dag(
  x,
  sd_rep = NULL,
  edge_label = c("value_and_stars", "value", "name"),
  digits = 2,
  ...
)

Arguments

x

Output of read_dsem_arrows, or a fitted model whose data holds one (Setup_Mod_DSEM then fit_model).

sd_rep

Optional RTMB::sdreport of that fit, for the p values. Read from x$sd_rep when the fit has one.

edge_label

What to write on each edge: the estimate with stars for its p value (*** below 0.001, ** below 0.01, * below 0.05), the estimate alone, or the parameter name. A fixed arrow shows its value in every case, and a bare arrow set has no estimates, so it is labeled with names.

digits

Digits to show for an estimate.

...

Passed to igraph::plot.igraph, such as vertex.size.

Value

The igraph object, invisibly. Its edge attributes hold each arrow's lag, estimate, standard error and p value.
