Experimental design in CRD and RCBD

Description

Function to deploy field-book experiments for completely randomized designs (CRD/DCA) and randomized complete block designs (RCBD/DBCA).

Usage

design_repblock(
  nfactors = 1,
  factors,
  type = "crd",
  rep = 3,
  zigzag = FALSE,
  nrows = NA,
  serie = 1000,
  seed = NULL,
  project = "inkaverse",
  qrcode = "{project}{plots}"
)

Arguments

nfactors	Number of factors in the experiment ⁠[numeric: 1]⁠.
factors	Named list with the levels of each factor ⁠[list]⁠.
type	Type of experimental arrangement ⁠[character: "crd", "rcbd"]⁠. The aliases "dca" and "dbca" are also accepted. The former "lsd" branch is intentionally disabled because it did not generate a valid Latin square design.
rep	Number of replications or blocks in the experiment ⁠[numeric: 3]⁠.
zigzag	Arrange the physical layout in zigzag order ⁠[logical: FALSE]⁠.
nrows	Number of rows in the physical field layout. When missing, the number of replications or blocks is used.
serie	Base number used to generate plot identifiers ⁠[numeric: 1000]⁠.
seed	Seed used for reproducible randomization ⁠[numeric: NULL]⁠.
project	Barcode prefix for data collection ⁠[character: "inkaverse"]⁠.
qrcode	Template used to concatenate QR-code fields ⁠[character: "{project}{plots}"]⁠. The placeholder {factors} expands to all factor columns.

Value

A list with the field-book design and parameters.

Examples

## Not run: 

library(inti)

factores <- list(
  "geno" = c("A", "B", "C", "D", "D", 1, NA, NULL, "NA"),
  "salt stress" = c(0, 50, 200, 200, "T0", NA, NULL, "NULL"),
  "time" = c(30, 60, 90)
)

fb <- design_repblock(
  nfactors = 3,
  factors = factores,
  type = "rcbd",
  rep = 5,
  zigzag = TRUE,
  seed = 123,
  nrows = 5,
  qrcode = "{project}{plots}"
)

dsg <- fb$fieldbook

fb %>%
