使用颜色列在R中复杂的堆积条形图

我正在尝试使用R制作堆叠的条形图 . 主要的关键点是使用图中颜色列的颜色 .

情节要求：

• 每个条形（x轴）应代表一个时间 .

• 每个物种应该是适当的颜色（由颜色栏给出），其在条形图上的空间反映丰度（y轴） .

• 在每个酒吧内，同一门的物种应该组合在一起 .

• 设置条的宽度真的很酷，但不是必需的 .

数据集的特征：

• 每个物种都有一种单独的颜色，物种的颜色由它们的门进行渐变 .

• 一段时间内物种的丰度总和为100 .

• 并非每个物种都在每一次

• 有7次，8门，132种

关于如何表示这些数据的其他想法是受欢迎的 .

代表数据：

先感谢您;我正用这个把头撞在墙上 .

#reshape the dataframes as matrices
