RCBD | R Documentation |
It randomly generates a randomized complete block design (RCBD) across locations.
RCBD(
t = NULL,
reps = NULL,
l = 1,
plotNumber = 101,
continuous = FALSE,
planter = "serpentine",
seed = NULL,
locationNames = NULL,
data = NULL
)
t |
An integer number with total number of treatments or a vector of dimension t with labels. |
reps |
Number of replicates (full blocks) of each treatment. |
l |
Number of locations. By default |
plotNumber |
Numeric vector with the starting plot number for each location. By default |
continuous |
Logical value for plot number continuous or not. By default |
planter |
Option for |
seed |
(optional) Real number that specifies the starting seed to obtain reproducible designs. |
locationNames |
(optional) Names for each location. |
data |
(optional) Data frame with the labels of treatments. |
A list with five elements.
infoDesign
is a list with information on the design parameters.
layoutRandom
is the RCBD layout randomization for each location.
plotNumber
is the plot number layout for each location.
fieldBook
is a data frame with the RCBD field book design.
