如何让用户在writecsv中选择输出文件名 [英] How to let user choose output file name in writecsv

问题描述

有什么想法让用户选择使用此功能保存的文件名吗?

Any idea how to let the user choose the filename to save using this function ?

write.csv(tweets, file = "newfile.csv",
          row.names = TRUE, sep = ',', 
          col.names = TRUE)

类似于我们使用另存为功能然后显示浏览器选项的方式.

Something like how we use the save as function and then a browser option appears.

推荐答案

尝试

Try ?file.choose. That should bring up the window that lets you navigate to the folder you want, and enter the file name you want to save under. That is:

write.csv(tweets, file=file.choose(), row.names=TRUE, sep=',', 
          col.names=TRUE)
