getnetwork | R Documentation |
Easily extract a network from one of the nodes in a networktree object
getnetwork(tree, id = 1L, transform = "detect", verbose = FALSE, ...)
tree |
a networktree object |
id |
the node in the tree to extract. Use summary(tree) to see id numbers for each split |
transform |
should stored correlation matrices be transformed to partial correlations or graphical lasso? Can be set to "cor", "pcor", or "glasso". Defaults to automatic detection |
verbose |
should warnings and messages from transformation functions (qgraph) be printed? |
... |
arguments passed to qgraph (e.g., "tuning", "threshold") |
