`gplotTwoWay`

produces box-and-whisker, violin plots, and error bars for two-way layout.

```
gplotTwoWay(formula, data, type = c("errorbar", "violin", "boxplot"),
color_manual = NULL, back_color = FALSE, xlab = NULL, ylab = NULL,
title = NULL, legend.title = NULL, width = NULL, option = c("sd", "se"),
na.rm = TRUE)
```

`formula` |
a formula of the form |

`data` |
a data frame containing the variables in |

`type` |
a character string to select one of the plots. "errorbar": error bar, "violin": violin plot, and "boxplot": box-and-whisker plot. |

`color_manual` |
a vector of colors. A palette can also be defined with |

`back_color` |
a logical to make background grey or white. |

`xlab` |
a label for the x axis, defaults to a description of x. |

`ylab` |
a label for the y axis, defaults to a description of y. |

`title` |
a main title for the plot. |

`legend.title` |
a legend title for the plot. |

`width` |
a numeric giving the width of the little lines at the tops and bottoms of the error bars (defaults to 0.35) and the width of the boxes for box-and-whisker plots (defaults to 0.75). |

`option` |
a character string to select one of the options to draw error bars with standard error or standard deviation. "se": standard error, "sd": standard deviation. Defaults to "se". |

`na.rm` |
a logical indicating whether NA values should be stripped before the computation proceeds. |

The upper whisker of box-and-whisker plots extends from the hinge to the highest value that is within 1.5 * IQR of the hinge, where IQR is the inter-quartile range. The lower whisker extends from the hinge to the lowest value within 1.5 * IQR of the hinge. Data out of the ends of the whiskers are outliers and plotted as points.
