NAs in chamber_wp and auto_wp

[jessicaguo]

Why are there so many NAs for water_potential_mean in both tables?

[jessicaguo]

Two reasons:

1. Most datasets are only chamber or only auto. Therefore, for each chamber-only dataset, there is a single NA in water_potential_mean in the auto_wp, and vice versa for auto-only datasets.

2. Some values were provided as NA. Data contributors may have included rows that were ultimately deemed NA, perhaps due to access issues, tank ran out of N₂, etc. We did not pre-emptively remove these from the database.

Solution: Feel free to filter out the NA's in your analysis!
