nat 1.8.0

This is tagged as a major release because of a change in behaviour that (by default) suppresses interactive rgl windows when running in batch (non-interactive) mode. See ?nat "rgl Package" section for details.

• nat will only activate an rgl display in interactive mode, otherwise defaulting to rgl's NULL mode display. This should help run nat in batch mode situations including knitr runs, the CRAN build server etc. (#272)
• Add summary.neuron(list) functions to calculate tree statistics such as number of nodes and cable length for neurons/neuronlists (#269)
• Automate progress bar in nlapply - this will always show in interactive mode when there are more than 10 neurons being processed. (#271)
• Fix bug in c.neuronlist when combining more than 2 neuronlists (#270)
• Fix bug in read.neuronlistfh on Windows (#268)
• Fix bug when constructing an ngraph with a single node (#267)
• Fix bug in [<-.neuronlist when assigning a whole data.frame using (#256)
• Fix bug in bounding box with input = "bounds" (#273)
• Documentation improvements (especiall package overview - see ?nat)
