data.tree (version 0.7.0)

Set: 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

# NOT RUN {
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")
 
# }
