Now really added it.

+
+This package contains functions that create and manipulate vocalisation
+diagrams. Vocalisation diagrams date back to early work in psychiatry
+(Jaffe and Feldstein, 1970) and social psychology (Dabbs and Ruback,
+1987) but have only recently been employed as a data representation
+method for machine learning (Luz, 2013; Luz and Kane, 2009).
+
+This provides a number of functions for generating vocalisation
+diagrams (vocaldias) from data frames containing, minimally, a column
+for start time of a vocalisation event (speech, silence, group-talk
+etc), a column for end time, and a column for the event identifier. It
+also contains some basic functions for reading and processing files
+from DementiaBank (.cha transcripts and audio files). 
+
+Functions `getSampledVocalMatrix` and `getTurnTakingProbMatrix`
+generate alternative versions of adjacency matrices for
+vocaldias. `staticMatrix` generates steady state diagrams from a
+vocaldia. `printARFFfile` generates a 'flat' representation of
+vocaldias for classifier training and evaluation.
+
+## Installation
+
+You can install the released version of vocaldia from [CRAN](https://CRAN.R-project.org) with:
+
+``` r
+install.packages("vocaldia")
+```
+
+## Example
+
+The following examples illustrate the use of vocaldia to create and
+visualise vocalisation graphs and their properties. 
+
+
+``` r
+library(vocaldia)
+## load some data
+data(vocdia)
+
+## select a dialogue
+x <- subset(atddia, id=='Abbott_Maddock_01')
+
+## show a probability matrix 
+getTurnTakingProbMatrix(x)
+
+## if you have igraph installed, visualise a vocal matrix
+require('igraph')
+subset(atddia, id=='Abbott_Maddock_01') %>% 
+    getSampledVocalMatrix(individual=TRUE, nodecolumn='speaker') 
+    %>% igraph.vocaldia %>% plot
+
+## plot steady state of the Markov diagram
+plot(staticMatrix(vocmatrix$ttarray, digits=4, history=TRUE))
+```
