R创建一个数据透视表，计算多个组的百分比

这是我的样本数据集

sample <- structure(list(Week  = c(1, 1, 1, 1, 1, 1, 1, 1, 2, 2, 2, 2, 2, 2),
                         Project = c("A", "A", "A",  "A",  "B",  "B",  "B",  "B",  "C",  "C",  "C",  "A", "A",   "A" ), 
                    Status= c( "Active","Rescheduled","Active", "Cancelled", "Active", "Cancelled",  "Cancelled", 
                               "Rescheduled",  "Active",  "Active",   "Rescheduled", "Cancelled", "Cancelled", "Active")),
                    .Names = c("Week","Project","Status"),
                      class = "data.frame" , row.names = c(NA, -14L))

> sample
   Week Project      Status
1     1       A      Active
2     1       A Rescheduled
3     1       A      Active
4     1       A   Cancelled
5     1       B      Active
6     1       B   Cancelled
7     1       B   Cancelled
8     1       B Rescheduled
9     2       C      Active
10    2       C      Active
11    2       C Rescheduled
12    2       A   Cancelled
13    2       A   Cancelled
14    2       A      Active

我想创建一个数据框架，按周计算每个程序的有效率和1-有效率(=非有效率)，值为"NA"

所以桌子看起来是这样的

  Week A_active_rate A_Non_active_rate B_active_rate B_Non_active_rate C_active_rate C_Non_active_rate
1    1          0.50              0.50          0.25              0.75            NA                NA
2    2          0.33              0.67            NA                NA          0.67              0.33
