STRIPLOT {AgroR}

Analysis: DBC experiments in strip-plot

Description

Analysis of an experiment conducted in a block randomized design in a strit-plot scheme using fixed effects analysis of variance.

Usage

STRIPLOT(
  f1,
  f2,
  block,
  response,
  norm = "sw",
  alpha.f = 0.05,
  transf = 1,
  textsize = 12,
  labelsize = 4,
  constant = 0
)

Arguments

f1

Numeric or complex vector with plot levels

f2

Numeric or complex vector with subplot levels

block

Numeric or complex vector with blocks

response

Numeric vector with responses

norm

Error normality test (default is Shapiro-Wilk)

alpha.f

Level of significance of the F test (default is 0.05)

transf

Applies data transformation (default is 1; for log consider 0)

textsize

Font size (default is 12)

labelsize

Label size (default is 4)

constant

Add a constant for transformation (enter value)

Value

The table of analysis of variance, the test of normality of errors (Shapiro-Wilk, Lilliefors, Anderson-Darling, Cramer-von Mises, Pearson and Shapiro-Francia), the test of homogeneity of variances (Bartlett). The function also returns a standardized residual plot.
