createWorkbook(type = ext) 错误：R 中的未知格式数据

Question

我用 R 制作了一个由 9 列组成的数据集，其中 2 列是字符，其余是数字，为此我使用了命令 data.frame 我想将我计算机中的数据集保存在 excel 文件中，因此我使用以下代码：

write.xlsx(new_data, file)

其中文件是我要保存的目的地。我已经多次尝试过该命令并且它运行良好但是这次我收到一条错误消息：

Error in createWorkbook(type = ext) : Unknown format Data

我不知道如何解决这个问题。我已经下载了相应的包来使用那个命令，我也在使用这个库，所以这不是问题。

部分数据集如下所示：

structure(list(Year = c(2020, 2020, 2020, 2020, 2020, 2020, 2020, 
2020, 2020, 2020, 2020, 2020, 2021, 2021, 2021, 2020, 2020, 2020,

我使用的代码是

new_data <- data.frame("Year" = data1$Year, "Month"= data1$Month, "Country" = data1$Country, "Week" = data1$Weekly_Avg, "Monthly_Avg" = Monthly_Avg, "Yearly_Avg" = Yearly_Avh, "Price1" = data2$Price_1, "Price2" = data2$Price_2, "Price3" = data2$Price_3)

write.xlsx(new_data, "C:/Users/MK/Documents/Project/Data")

我从不同的数据集中获取这些数据，将它们放在一起后，其格式为 grouped_df。我试图将其设为如上所示的数据框，但我仍然无法将其保存在 excel 文件中。

非常感谢任何帮助。或者关于如何在我的计算机上保存该数据集的任何其他想法。

提前致谢！

Answer 1

问题出在输出名称上。需要扩展名“xlsx”。

write.xlsx(new_data, "C:/Users/MK/Documents/Project/Data.xlsx")

我遇到了同样的问题，然后就解决了。

Answer 2

如前所述，需要“.xlsx”扩展名。但是，如果您已经定义了路径，则无需在命令中将其写出来：

write.xlsx(new_data, "Data.xlsx")

如果您想将其放在自己的文件夹中，只需在名称（即文件夹名称“New Data”）前添加即可：

write.xlsx(new_data, "New Data/Data.xlsx")
