`f1` |
Numeric or complex vector with factor 1 levels |

`f2` |
Numeric or complex vector with factor 2 levels |

`block` |
Numerical or complex vector with blocks |

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

`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; 'angular' for angular transformation) |

`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'. |

`legend` |
Legend title name |

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

`angle` |
x-axis scale text rotation |

`textsize` |
font size |

`labelsize` |
label size |

`dec` |
number of cells |

`family` |
font family |

`point` |
if quali=FALSE, defines whether to plot all points ("all"), mean ("mean"), standard deviation ("mean_sd" - |

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

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

`CV` |
Plotting the coefficient of variation and p-value of Anova ( |

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

`color` |
Column chart color ( |

`posi` |
Legend position |

`ylim` |
y-axis scale |

`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 or Levene), the test of independence of Durbin-Watson errors, 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 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.

The function does not perform multiple regression in the case of two quantitative factors.

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.
