Minor Release

Version 0.3.3

• CHANGE: Renamed Find method to FindNode, in order to avoid masking from base
• FIX: upgrade to latest version of treemap package
• FIX: a few typos in documentation

Minor Release

Version 0.3.2

• ADD: FromListExplicit now interprets character vectors as a list of nodes (#58)

Minor Release

• IMPROVE: as.list.Node
  • now generates auto name if unique name is not available (#54)
  • now has warn arg, warning if source data contains reserved names
  • now also imports fiels with names equal to reserved names (e.g. count), they will be renamed (to e.g. count2)
• CHANGE: node$leaves now returns a list even when called on a leaf itself
• ADD: Find method to find a single Node in a (sub-)tree (#52)

Apple Tree

In Celtic mythology, the apple tree is a symbol for fruitfulness. May data.tree blossom and fructify!
In the Ulster Cycle, the soul of Cú Roí was confined in an apple that lay in the stomach of a salmon which appeared once every seven years. Let's hope that the next data.tree release will appear earlier!

Release Notes

• REMOVE: Removed the cacheAttribute parameter from Aggregate and Cumulate (they were confusing, even to me. Use Do instead to manually store aggregate values in the tree)
• ADD: plot function (see ?plot.Node)
• ADD: ToDataFrameTypeCol to export e.g. the path to columns by level in columns: ToDataFrameTypeCol(acme)
• ADD: Node$AddSibling
• ADD: Node$RemoveAttribute now contains a mandatory parameter so that it can be used if the node does not have the attribute to be removed.
• ADD: Get works on methods without args
• IMPROVE: FormatFixedDecimal and FormatPercent work for NULL values
• IMPROVE: Documentation
• FIX: Aggregate will not return attribute from callee anymore, but always aggregate children attributes
• FIX: Removed ... parameter from ToListExplicit and ToListSimple
• FIX: Clone was adding empty children list, which caused a series of problems (#44)
• FIX: Cloning a subtree does not keep reference to un-cloned parent anymore (#49)
• FIX: print with limit parameter ignored formatter (#43)
• FIX: cannot rename to int, e.g. acme$Do(function(x) x$name <- x$position) (#53)

Maintenance Release

• FIX: applications vignette, changed from http://htmlwidgets.org to http://www.htmlwidgets.org, as requested by CRAN

Maintenance Release

• FIX #33: applications vignette doesn't build because of DiagrammeR update
• FIX #32: Cannot subclass Node
• FIX #30: strange errors when using data.tree multiple times

Maintenance Release

• FIX: Get can now fetch vectors and matrices too
• ADD: Node$siblings

Elder

This is release 0.2.0-3 on CRAN

• ADD: ClimbByAttribute
• FIX: Aggregate and Cumulate now work always on attributes having a formatter
• ADD: as.igraph now has a 'directed' parameter
• ADD: print.Node now has a pruneMethod, allowing different methods to avoid that a huge tree is printed to the console
• REMOVE: FromDataFrameTaxonomy and ToDataFrameTaxonomy (replaced by FromDataFrameNetwork and ToDataFrameNetwork, but with some differences)
• ADD: FromDataFrameNetwork and ToDataFrameNetwork
• IMPROVE: make Traversal "level" much faster
• ADD: Node$RemoveChild
• ADD: Node$RemoveAttribute
• ADD: as.igraph.Node now supports different directions (climb and descend)
