.Of course My usual suspects for Time Series Readings are -
1) The seminal pdf (2008!!) by a certain Prof Hyndman
2) JSS Paper -Automatic Time Series Forecasting: The forecast
Package for R http://www.jstatsoft.org/v27/i03/paper
3) The CRAN View http://cran.r-project.org/web/views/TimeSeries.html
This is cluttered and getting more and more cluttered. Some help on helping recent converts to R, especially in the field of corporate forecasting or time series for business analytics would really help.
Avril does an awesome job with this curiously named ( ;) ) booklet at http://a-little-book-of-r-for-time-series.readthedocs.org/en/latest/src/timeseries.html
