## Other notes

* baker.strawberry.uniformity: inserted 3 columns into the layout of the field to more closely align with the experiment layout.
* garber.multi.uniformity: The data has been reshaped from wide to tall and additional years added.
* minnesota.barley.yield: Added 10+ more years of data.
* odland.soyhay.uniformity: Yields have been divided by 10 so that the yield values are now in units of "tons" instead of "0.1 tons".
* shafi.tomato.uniformity: Had incorrect yield scale, now divided by 1000.
* Documentation pages now created via Github Actions. (Issue #12). Thanks to E.Tanaka.


# agridat 1.23 (2024-01-30)

## New datasets

## Other notes

* Removed suggested use of sf/terra packages in examples.

* cochran.eelworms - Fix a typo reported by U.Genschel, and added more columns for grain yield, straw yield, weeds. Updates to documentation.
