在R中转换数据帧格式

我有一个如下所示的数据框：

Type    Availability   Count

DayTime   Cancelled       10
Morning   Cancelled       15
Night     Cancelled       13
DayTime   Trip Completed  14
Morning   Trip Completed  71
Night     Trip Completed  32
DayTime   Not-Present     13
Morning   Not-Present     43
Night     Not-Present     23

我想把这个数据帧转换成只有3行的格式，即白天、早上和晚上。和3列，即已取消、跳闸已完成和不存在，将有各自的计数。

---

我怎样才能在R中做到这一点？请帮忙

看看

tidyr:：spread

my_data <- tibble::tribble(
  ~Type,    ~Availability,   ~Count,

"DayTime",   "Cancelled",       10,
"Morning",   "Cancelled",       15,
"Night",     "Cancelled",       13,
"DayTime",   "Trip Completed",  14,
"Morning",   "Trip Completed",  71,
"Night",     "Trip Completed",  32,
"DayTime",   "Not-Present",     13,
"Morning",   "Not-Present",     43,
"Night",     "Not-Present",     23
)

my_data %>% tidyr::spread(key = Availability, value = Count)

my_数据%tidyr:：spread（键=可用性，值=计数）

试试

xtabs（Count~Type+Availability，data=dat）

。是的，我发现这是一个从长到宽格式的简单例子。是的，你明白了
