Organize trait ranks in a ClimMob data

Description

This function helps in identifying the traits assessed in the tricot project and validates the data returning a list with logical vectors to support the transformation of tricot rankings into a PlackettLuce ranking

Usage

getTraitList(data, pattern, trait.labels = NULL, ...)

Arguments

data

data.frame, the ClimMob data

pattern

character, the tricot ranking pattern

trait.labels

an optional character with clean trait labels

Value

a list with trait validation data

Examples


require("gosset")

data("breadwheat", package = "gosset")

getTraitList(breadwheat, c("_best", "_worst"))

Set an experimental incomplete block design

Description

Generate an incomplete block A-optional design. The function is optimized for incomplete blocks of three, but it will also work with comparisons of any other number of options. The design strives for approximate A optimality, this means that it is robust to missing observations. It also strives for balance for positions of each option. Options are equally divided between first, second, third, etc. position. The strategy is to create a "pool" of combinations that does not repeat combinations and is A-optimal. Then this pool is ordered to make subsets of consecutive combinations also relatively balanced and A-optimal

Usage

randomize(
  npackages,
  itemnames,
  ncomp = 3,
  availability = NULL,
  props = NULL,
  ...
)

Arguments

npackages

an integer for the number of incomplete blocks to be generated

itemnames

a character for the name of items tested in the experiment

ncomp

an integer for the number of items to be assigned to each incomplete block

availability

optional, a vector with integers indicating the number of plots available for each itemnames

props

optional, a numeric vector with the desired proportions for each itemnames

...

additional arguments passed to methods

Value

A dataframe with the randomized design

  # pass the comparison with local item as an additional rankings, then
  # each of the 3 varieties are compared separately with the local item
  # and return an object of class grouped_rankings

Remove geographical identity

Description

Build a buffer around the a set of geographical coordinates and take a random point around the buffer. The function is used to omit the precise location of tricot participants but keeping a close distance to the trial environment.

Arguments

longlat

a data.frame or matrix with geographical coordinates long lat

dist

numeric, buffer distance for all lonlat

nQuadSegs

integer, number of segments per quadrant

...

further arguments passed to sf methods

Value

A data frame with the random coordinates long lat within the buffer

Examples


xy = matrix(c(11.097799, 60.801090,
               11.161298, 60.804199,
               11.254428, 60.822457),
             nrow = 3, ncol = 2, byrow = TRUE)

#' the function also handles NAs

xy2 = matrix(c(11.097799, 60.801090,
