如何將csv文件從R中的一個目錄複製到另一個目錄中

Question

我能夠使用下面的代碼複製文件/子目錄，但我只想複製csv文件。

dir.create(new_directory) 
file.copy(from = old_directory, to = new_directory, recursive = TRUE) 

Answer 1

你試過這個嗎？

file.copy(from = "old_path/*.csv", to ="new_path/", recursive = TRUE) 

Answer 2

這應該工作：

fls <- list.files(pattern='*.csv') 
file.copy(fls, 
      to = "new_directory", recursive = TRUE, 
      overwrite = TRUE, copy.mode = TRUE, copy.date = FALSE)
