r - 将 slidify 发布到 Dropbox 时遇到问题

Question

我创建了一个slidify幻灯片，但是当我尝试将我的保管箱帐户放入公用文件夹时，我得到一个warning：

publish("Slides", host = "dropbox")

Creating slide directory at ~/Dropbox/Public/Slides
Copying files to ~/Dropbox/Public/Slides
[1] FALSE
Warning messages:
1: In file.copy(".", drop_dir, overwrite = F, recursive = TRUE) :
  'recursive' will be ignored as 'to' is not a single existing directory
2: In file.create(to[okay]) :
  cannot create file '~/Dropbox/Public/Slides', reason 'No such file or directory'

我尝试hard symbolic link按照http://thiagosilva.wordpress.com/2013/02/17/installing-slidify-on-a-windows-machine/的建议创建一个。

但是警告仍然存在...

有任何想法吗？

此致！
