Distribute the sample on the plate — spatial • experDesign

This function assumes that to process the batch the samples are distributed in a plate with a grid scheme.

Usage

spatial(
  index,
  pheno,
  omit = NULL,
  remove_positions = NULL,
  rows = LETTERS[1:5],
  columns = 1:10,
  iterations = 500
)

Arguments

index: A list with the samples on each subgroup, as provided from design() or replicates().
pheno: Data.frame with the sample information.
omit: Name of the columns of the pheno that will be omitted.
remove_positions: Character, name of positions to be avoided in the grid.
rows: Character, name of the rows to be used.
columns: Character, name of the rows to be used.
iterations: Numeric value of iterations that will be performed.

Value

The indices of which samples go with which batch.

Examples

data(survey, package = "MASS")
index <- design(survey[, c("Sex", "Smoke", "Age")], size_subset = 50,
                iterations = 10)
#> Warning: There might be some problems with the data use check_data().
index2 <- spatial(index, survey[, c("Sex", "Smoke", "Age")], iterations = 10)
head(index2)
