r - R中的堆积柱形图

Question

我想知道（如果可能的话）如何在R中绘制这样的图。

例如 30 人（x 轴），工作将近 300-400 小时（y 轴），每个人在 6 个特定活动中分配的时间以彩色显示。

示例数据：

| People | Act 1 | Act 2 | Act 3 | Act 4 | Act 5 | Act 6 |
|Person 1|   18  |   20  |   32  |   75  |   64  |   18  |
|Person 1|   40  |   25  |   02  |   04  |   17  |   20  |
|Person 2|   58  |   45  |   32  |   75  |   64  |   18  |
|Person 3|   10  |   15  |   11  |   28  |   15  |   92  |
|Person 1|   11  |   11  |   02  |   05  |   04  |   08  |

我正在使用这段代码：

plot(table(data$worker),col=unique(data$worker))

（这段代码给了我每个条不同的颜色）

但我找不到根据我上面提到的标准为每个条着色的方法。

您需要一个堆积柱形图，它在 y 轴上显示每人工作时间的绝对值（总计），每种活动类型。

首先，像这样组织您的数据集：

person hours.worked activity
1      18           1
1      20           2
...
3      11           3
3      28           4
...
1      4            5
1      8            6

然后，执行以下操作：

#reproducible example (same as OP's data)
df = structure(list(person = c(1L, 1L, 1L, 1L, 1L, 1L, 1L, 1L, 1L, 1L, 1L, 1L, 2L, 2L, 2L, 2L, 2L, 2L, 3L, 3L, 3L, 3L, 3L, 3L, 1L, 1L, 1L, 1L, 1L, 1L),
                    hours.worked = c(18L, 20L, 32L, 75L, 64L,18L, 40L, 25L, 2L, 4L, 17L, 20L, 58L, 45L, 32L, 75L, 64L, 18L, 10L, 15L, 11L, 28L, 15L, 92L, 11L, 11L, 2L, 5L, 4L, 8L),
                    activity = c(1L, 2L, 3L, 4L, 5L, 6L, 1L, 2L, 3L, 4L, 5L, 6L, 1L, 2L, 3L, 4L, 5L, 6L, 1L, 2L, 3L, 4L, 5L, 6L, 1L, 2L, 3L, 4L, 5L, 6L)),
                   .Names = c("person", "hours.worked", "activity"), 
               class = "data.frame",
               row.names = c(NA, -30L))

df$person = factor(df$person,levels=c(1,2,3)) #control person order in x axis (left to right)
df$activity = factor(df$activity,levels=c(6,5,4,3,2,1)) #control order of stacks within column (top to base)

library(ggplot2)

ggplot(data=df, aes(x=person,y=hours.worked,fill=activity)) +
  geom_col(position="stack") +
  scale_fill_manual(breaks = c(1,2,3,4,5,6), #control order of legend keys (top to bottom)
                    values = c("#F564E3","#619CFF","#00BFC4","#00BA38","#B79F00","#F8766D")) #control fill of legend keys and columns stacks (surprisingly, this will honor the order of factor levels instead of order of 'breaks')
