I'm a beginning R user. The data: Volume of nectar in flowers under 4 different treatments, nested for individual (measures were taken mutliple times from different flowers of the same individual- never the same flower).
Specs: 54% of the data = 0. Variance=3.89. Mean=1.03. Sample size per treatment varies, all are >20. I am trying to determine if treatment had any impact on nectar volume.
