There are three primitive functions included in FielDHub:
print(), summary(), and
plot().
Given an experiment simulation from FielDHub, we can use these functions to display different kinds of information about the experiment. In this example, we will use the following randomized complete block design:
experiment <- RCBD(
t = 12,
reps = 3,
l = 2,
plotNumber = c(1001, 2001),
locationNames = c("A", "B"),
seed = 123
)
print()
The print() function prints the design parameters of the
experiment and the first 10 rows of the field book. The first 10 rows of
the field book are saved if the output of this function is assigned to a
variable.
print(experiment)
Randomized Complete Block Design (RCBD):
Information on the design parameters:
List of 7
$ blocks : num 3
$ number.of.treatments: num 12
$ treatments : chr [1:12] "T1" "T2" "T3" "T4" ...
$ locations : num 2
$ plotNumber : num [1:6] 1001 1101 1201 2001 2101 ...
$ locationNames : chr [1:2] "A" "B"
$ seed : num 123
10 First observations of the data frame with the RCBD field book:

summary()
The summary() function outputs a list of the design
parameters and the layout randomization with plot numbers.

Randomized Complete Block Design (RCBD):
1. Information on the design parameters:
List of 8
$ blocks : num 3
$ number.of.treatments: num 12
$ treatments : chr [1:12] "T1" "T2" "T3" "T4" ...
$ locations : num 2

$ locationNames : chr [1:2] "A" "B"
$ seed : num 123
$ id_design : num 2
2. Layout randomization for each location:
$Loc_A

[2,] "2" "T11 T5 T3 T9 T4 T1 T7 T12 T10 T2 T6 T8"
[3,] "3" "T9 T3 T4 T1 T11 T7 T5 T10 T8 T2 T12 T6"
$Loc_B
Block --Treatments--
[1,] "1" "T9 T12 T10 T7 T3 T4 T5 T6 T8 T2 T1 T11"

[3,] "3" "T12 T4 T6 T8 T10 T9 T1 T2 T7 T5 T3 T11"
3. Plot numbers layout:
