Hi, I'm with data (https://drive.google.com/open?id=1JdgsnJn5VrkL8j1BsfWzqYW9fMGXND6U) from a completely randomized experiment, in which it was evaluated the growth of a fungus in response to application of different doses (0.25, 0.50, 0.75 and 1.00) of different fungicides (natural + 1 4 + chemical control with water). In total 24 treatments x 4 reps each.
As I have no experience of R, I would like to know what the appropriate script to perform the ANOVA, regression and generate the graphics already adjusted for each situation.
A little rusty on this, but with every combo of fungicides, it sounds like a 6X4 factorial design.
Here's a fairly detailed step by step by through a 2X3 factorial design.
However, I'd pair that with a textbook.
If you internet search for "Factorial Anova in R" and similar search terms, you'll find a ton more vignettes, guides, and videos, of varying quality.
