DQLT {AgroR} | R Documentation |

Function of the AgroR package for the analysis of experiments conducted in a balanced qualitative single-square Latin design with multiple assessments over time, however without considering time as a factor.

DQLT( trat, line, column, tempo, response, alpha.f = 0.05, alpha.t = 0.05, mcomp = "tukey", error = TRUE, xlab = "Independent", ylab = "Response", textsize = 12, labelsize = 5, family = "sans", sup = 0, addmean = F, posi = c(0.1, 0.8), geom = "bar", fill = "gray", legend = "Legend", ylim = NA, dec = 3, theme = theme_classic(), xnumeric = FALSE )

`trat` |
Numerical or complex vector with treatments |

`line` |
Numerical or complex vector with line |

`column` |
Numerical or complex vector with column |

`tempo` |
Numerical or complex vector with times |

`response` |
Numerical vector containing the response of the experiment. |

`alpha.f` |
Level of significance of the F test ( |

`alpha.t` |
Significance level of the multiple comparison test ( |

`mcomp` |
Multiple comparison test (Tukey ( |

`error` |
Add error bar |

`xlab` |
Treatments name (Accepts the |

`ylab` |
Variable response name (Accepts the |

`textsize` |
Font size of the texts and titles of the axes |

`labelsize` |
Font size of the labels |

`family` |
Font family |

`sup` |
Number of units above the standard deviation or average bar on the graph |

`addmean` |
Plot the average value on the graph ( |

`posi` |
Legend position |

`geom` |
Graph type (columns - "bar" or segments "point") |

`fill` |
Defines chart color (to generate different colors for different treatments, define fill = "trat") |

`legend` |
Legend title |

`ylim` |
y-axis scale |

`dec` |
Number of cells |

`theme` |

`xnumeric` |
Declare x as numeric ( |

The p-value of the analysis of variance, the normality test for Shapiro-Wilk errors, the Bartlett homogeneity test of variances, the independence of Durbin-Watson errors and the multiple comparison test ( Tukey, Scott-Knott, LSD or Duncan).

The function returns the p-value of Anova, the assumptions of normality of errors, homogeneity of variances and independence of errors, multiple comparison test, as well as a line graph

The ordering of the graph is according to the sequence in which the factor levels are arranged in the data sheet. The bars of the column and segment graphs are standard deviation.
