coords2df(coord_list)

coords2list(coord_df)

Arguments

coord_list

a named list of coordinates

coord_df

a data.frame with columns x, y, and name

Value

either a list or a data.frame with DAG node coordinates

Examples

library(dagitty) coords <- list( x = c(A = 1, B = 2, D = 3, C = 3, F = 3, E = 4, G = 5, H = 5, I = 5), y = c(A = 0, B = 0, D = 1, C = 0, F = -1, E = 0, G = 1, H = 0, I = -1) ) coord_df <- coords2df(coords) coords2list(coord_df)
#> $x #> A B D C F E G H I #> 1 2 3 3 3 4 5 5 5 #> #> $y #> A B D C F E G H I #> 0 0 1 0 -1 0 1 0 -1 #>
x <- dagitty('dag{ G <-> H <-> I <-> G D <- B -> C -> I <- F <- B <- A H <- E <- C -> G <- D }') coordinates(x) <- coords2list(coord_df)
