Set: Traverse a Tree and Assign Values

In data.tree: General Purpose Hierarchical Data Structure

Traverse a Tree and Assign Values

Description

The method takes one or more vectors as an argument. It traverses the tree, whereby the values are picked from the vector. Also available as OO-style method on Node.

Usage

#OO-style:
# node$Set(..., 
#          traversal = c("pre-order", "post-order", "in-order", "level", "ancestor"),  
#          pruneFun = NULL, 
#          filterFun = NULL)
#traditional:
Set(nodes, ...)

Arguments

nodes	The nodes on which to perform the Get (typically obtained via Traverse)
...	each argument can be a vector of values to be assigned. Recycled.

Value

invisibly returns the nodes (useful for chaining)

Examples

data(acme)
acme$Set(departmentId = 1:acme$totalCount, openingHours = NULL, traversal = "post-order")
acme$Set(head = c("Jack Brown", 
                  "Mona Moneyhead", 
                  "Dr. Frank N. Stein", 
                  "Eric Nerdahl"
                  ),
         filterFun = function(x) !x$isLeaf
        )
print(acme, "departmentId", "head")
