如何递归地将csv文件从一个目录复制到另一个目录中

Question

我可以使用下面的代码复制文件/子目录，但我只想复制csv文件。

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

Answer 1

这应该有效：

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

Answer 2

你试过这个吗？

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