Changes in version 0.0.4                        

New features

  - graphs are now using ggplot2

                        Changes in version 0.0.3                        

Bug fixes

  - fix issue #11 where the likelihood surface was incorrectly
    calculated. This unfortunately reverts the issue from #4

                        Changes in version 0.0.2

    in constant zeros when reverted back to the likelihood scale

                 Changes in version 0.0.1 (2017-12-06)                  

The main features of the package include:

  - get_R: a function to estimate R as well as the force of infection
    over time, from incidence data; output is an object of class earlyR

  - sample_R: a function to obtain a sample of likely R values

  - plot: a function to visualise earlyR objects (R or force of
    infection).

  - points: a function using earlyR objects to add the force of
    infection to an existing plot.
