`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 ( |

`homog` |
Homogeneity test of variances ( |

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

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

`quali` |
Defines whether the factor is quantitative or qualitative ( |

`mcomp` |
Multiple comparison test (Tukey ( |

`grau` |
Polynomial degree in case of quantitative factor ( |

`grau12` |
Polynomial degree in case of quantitative factor ( |

`grau21` |
Polynomial degree in case of quantitative factor ( |

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

`constant` |
Add a constant for transformation (enter value) |

`geom` |
Graph type (columns or segments (For simple effect only)) |

`theme` |
ggplot2 theme ( |

`ylab` |
Variable response name (Accepts the |

`xlab` |
Treatments name (Accepts the |

`xlab.factor` |
Provide a vector with two observations referring to the x-axis name of factors 1 and 2, respectively, when there is an isolated effect of the factors. This argument uses 'parse'. |

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

`angle` |
x-axis scale text rotation |

`family` |
Font family ( |

`color` |
When the columns are different colors (Set fill-in argument as "trat") |

`legend` |
Legend title name |

`errorbar` |
Plot the standard deviation bar on the graph (In the case of a segment and column graph) - |

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

`textsize` |
Font size ( |

`labelsize` |
Label size ( |

`dec` |
Number of cells ( |

`ylim` |
y-axis limit |

`posi` |
Legend position |

`point` |
Point type for regression ("mean_se","mean_sd","mean" or "all") |

`angle.label` |
Label angle |

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 test of multiple comparisons (Tukey, LSD, Scott-Knott or Duncan) or adjustment of regression models up to grade 3 polynomial, in the case of quantitative treatments. The column chart for qualitative treatments is also returned. The function also returns a standardized residual plot.

The order of the chart follows the alphabetical pattern. Please use 'scale_x_discrete' from package ggplot2, 'limits' argument to reorder x-axis. The bars of the column and segment graphs are standard deviation.

In the final output when transformation (transf argument) is different from 1, the columns resp and respo in the mean test are returned, indicating transformed and non-transformed mean, respectively.
