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.
- Add
if(require("asreml", quietly=TRUE)) to example
sections. This way we can allow people (or GitHub Actions) to force run
the dontrun sections, even if asreml is not
installed.
- cochran.eelworms - Fix a typo reported by U.Genschel, and added more
columns for grain yield, straw yield, weeds. Updates to
documentation.
- gartner.corn - Remove ‘rgdal’ package from example (Issue #11).

re-direct errors).
- Replaced use of
