Introduction

Below are two links to a mock dataset that we can use during the workshop series.

The Experiment

The mock data represents data from an experiment we conducted to evaluate the cumulative effects of drought and pathogen infeciton (disease) on an endemic and endangered species, the silver tree.

Silver Tree Trial

We measured the physiological response of the plants using some fancy equipment. At least 10 measurements were made on each plant 2-3 times a week for one month.

Physiological Measurements

Trees were split into trails and treatments and infected with one of two pathogen species. We also included controls that were not infected. Below is a quick summary of the experimental design.

The Data

Trial	Treatment	Species	Number of Plants
1	Drought	Control	9
1	Drought	Exotic Pathogen	9
1	Drought	Indigenous Pathogen	8
1	Wet	Control	9
1	Wet	Exotic Pathogen	8
1	Wet	Indigenous Pathogen	8
2	Drought	Control	8
2	Drought	Exotic Pathogen	7
2	Drought	Indigenous Pathogen	6
2	Wet	Control	8
2	Wet	Exotic Pathogen	7
2	Wet	Indigenous Pathogen	9

We will learn to produce summary tables like the one above in Session 3-Introduction to dplyr.
