pyrethrum_ray_blight

<p>An assessment of the incidence of ray blight disease of pyrethrum in 62
sampling units, containing 6 plants each.</p>

datasets

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
Madden LV, Hughes G, van den Bosch F (2007, ISBN: 978-089054-354-2) for
further information on these methods. Several data sets that were mainly
published in plant disease epidemiology literature are also included in this
package.
