is.intensity

is.count

is.incidence

is.severity

Test if an object is of class <code>intensity</code> or one of its subclasses
(i.e. <code>count</code>, <code>incidence</code> or <code>severity</code>).

A toolbox to make it easy to analyze plant disease epidemics. It
provides a common framework for plant disease intensity data recorded over
time and/or space. Implemented statistical methods are currently mainly
focused on spatial pattern analysis (e.g., aggregation indices, Taylor and
binary power laws, distribution fitting, SADIE and 'mapcomp' methods). See
Laurence V. Madden, Gareth Hughes, Franck van den Bosch (2007)
<doi:10.1094/9780890545058> for further information on these methods.
Several data sets that were mainly published in plant disease epidemiology
literature are also included in this package.
