| tagconnect {FaultTree} | R Documentation |
Interpretation of Node ID by tag Name
Description
Enables tree building improvement by allowing reference to nodes by tag.
Usage
tagconnect(DF, at, source=FALSE)
Arguments
DF |
A fault tree dataframe such as returned from ftree.make or related add... functions. |
at |
An ID value or tag name for reference to a node. |
source |
A logical indicating whether to evaluate multiple occurences of the tag to identify the source of duplication. Default of FALSE will cause the function to fail in case of multiple occurence of tag provided as 'at'. |
Value
Returns the ID value for the node whether it is a tag string or the actual ID value.
