This function allows you to plot an alluvial/Sankey diagram

1 | ```
data(melt_df)
``` |

`df` |
A dataframe containing each variable as a column; must be in molted form (see reshape package for details) |

`x_axis` |
the column in df containing the x axis information |

`grouping` |
the column in df containing the group identity information |

`weights` |
the column containing the y axis information |

`plot_title` |
str; title of your plot |

`xlab` |
str; x-axis label |

`ylab` |
str; y-axis label |

`axis_breaks` |
vector of how the x axis should be partitioned |

`has_lines` |
if TRUE, includes vertical line breaks separating along the axis_breaks |

`line_breaks` |
a vector that contains the x-values for where the lines should be manually placed. Only functional if has_lines = TRUE |

`add_values` |
if TRUE, includes values of the weights corresponding to the alluvium strata |

An object of class `"dataframe"`

yearaxes <- seq(1990, 2010, 5)
yearbreaks <- c(1991.3,1993.7,1996.3,1998.7,2001.3,2003.7,2006.3,2008.7)
plot_alluvium(df = melt_df, x_axis = melt_df$year, grouping = melt_df$factors,
weights = melt_df$value, plot_title = "Risk Factors for Stroke in Blacks",
xlab = "Year", ylab = "Cumulative Proportion", axis_breaks = yearaxes)
