10/05/2017 J6C1D6I6Z5W9S9H9K9Y9B9R9L9U3M9E9Q9X9V2N9O9 

每一行表示的座位在特定日期（例如，船的可用性：如果我們採取第一行的座位情況列，則J艙有有6個座位，C具有5等上..）

我必須檢查如何根據時間更改可用性。我們如何做到這一點？

我不確定以下輸出是否是您正在尋找的任何完整答案。我試圖將Seat Availability拆分成不同的columns（例如column name是seat row）。您現在可以使用plot這些數據或根據需要使用。

df <- data.frame(Dates=c("01/05/2017","02/05/2017","03/05/2017","04/05/2017","05/05/2017", 
         "06/05/2017","07/05/2017","08/05/2017","09/05/2017","10/05/2017"), 
       SeatAvailability=c("J6C5D6I6Z5W9S9H9K9Y9B9R9L9U9M9E9Q9X9V9N9O9","J7C6D6I6Z5W9S9H9K8Y9B9R9L9U9M9E9Q9X9V9N7O9", 
            "J6C1D6I6Z5W9S9H9K9Y9B9R9L9U3M9E9Q9X9V2N9O9","J6C6D6I6Z5W9S9H9K6Y9B9R9L4U9M9E9Q9X9V9N9O9", 
            "J6C6D8I6Z5W2S9H9K9Y9B9R9L9U9M9E9Q9X9V9N8O9","J6C6D6I6Z5W9S9H9K9Y9B9R9L9U9M9E9Q9X9V9N9O9", 
            "J6C6D6I6Z5W9S9H9K9Y9B9R7L9U9M9E9Q7X9V9N7O9","J6C6D6I6Z5W9S9H9K9Y9B9R9L9U9M9E9Q9X9V9N9O9", 
            "J8C6D6I6Z5W9S9H8K9Y9B9R9L9U9M9E9Q9X9V9N9O9","J6C1D6I6Z5W9S9H9K9Y9B9R9L9U3M9E9Q9X9V2N9O9")) 

df$Dates <- as.character(df$Dates) 
df$SeatAvailability <- as.character(df$SeatAvailability) 
df$SeatAvailability <- gsub("[^0-9]","",df$SeatAvailability) 
df <- data.frame(cbind(df$Dates, do.call('rbind', strsplit(as.character(df$SeatAvailability),"",fixed=TRUE)))) 

colnames(df) <- c("Dates","J","C","D","I","Z","W","S","H","K","Y","B","R","L","U","M","E","Q","X","V","N","O")
