Check the orthogonality with field/topographic characteristics

Check the orthogonality of the trial input rates and observed characteristics provided by the user

Usage

check_ortho_with_chars(td, sp_data_list, vars_list)

Arguments

td: (tibble) trial design data created by make_exp_plots() and assign_rates()
sp_data_list: (list) list of spatial datasets as `sf` from the `sf` package or `SpatRaster` from the `terra` package
vars_list: (list) list of character vectors indicating the name of the variables to be used in the datasets specified in sp_data_list

Value

a list
