R examples in Agronomy

Khaled Ibrahimi
Dear all,
Are there good R stat examples in the field of agronomy (especially field
experiments)?
Thanks

Re: R examples in Agronomy

R help mailing list-2
Hello,

For introductory material there is--of course--Immer's Barley Data
(popularized by Bill Cleveland), and used extensively in R to
demonstrate lattice graphics:

>library(lattice)
>?barley

Note the example dotplot() at the bottom of the "barley" help page,
and also on the "barchart" help page. The citation is included, and
there is also other commentary online:

Immer, R. F., H. K. Hayes, and LeRoy Powers. (1934). Statistical
Determination of Barley Varietal Adaptation.  Journal of the American
Society of Agronomy, 26, 403–419.
Wright, Kevin (2013). Revisiting Immer's Barley Data. The American
Statistician, 67(3), 129–133.

For a more extensive collection of agronomic data, take a look at the
"agridat" package. There's a nice vignette as well.

https://CRAN.R-project.org/package=agridat
https://cran.r-project.org/web/packages/agridat/vignettes/agridat_examples.pdf

HTH,

Bill.
