Coerce a UMG to a data frame

Returns the vertices or the edges of a diagram as a tidy data frame, which is convenient for inspection, tabulation in a manuscript, and programmatic edits before re-assembling with umg_model().

Usage

# S3 method for class 'umg'
as.data.frame(
  x,
  row.names = NULL,
  optional = FALSE,
  what = c("edges", "vertices"),
  ...
)

Arguments

x

An object of class umg.

row.names

Unused; present for S3 consistency.

optional

Unused; present for S3 consistency.

what

"edges" (default) returns one row per edge with columns from, to, kind, label, and fixed; "vertices" returns one row per vertex with columns name, label, observed, support, role, dist, fill, and annot.

...

Ignored.

Value

A data frame.

Examples

as.data.frame(umg_factor("F", paste0("y", 1:3)))
#>   from to kind          label fixed
#> 1    F y1  dep                    1
#> 2    F y2  dep $\\lambda_{2}$    NA
#> 3    F y3  dep $\\lambda_{3}$    NA
as.data.frame(umg_factor("F", paste0("y", 1:3)), what = "vertices")
#>   name  label observed    support role      dist fill annot
#> 1    F  $F_i$    FALSE continuous   rv N(0, psi) <NA>  <NA>
#> 2   y1 $y1_i$     TRUE continuous   rv      <NA> <NA>  <NA>
#> 3   y2 $y2_i$     TRUE continuous   rv      <NA> <NA>  <NA>
