推荐答案

未找到"zip"问题是ff软件包所独有的问题.这是一个简单的解决方案.

The 'zip' not found issue is a problem not unique to the ff package. Here is a simple solution.

1. 下载Rtools https://cran.r-project.org/bin/windows/Rtools/
2. 打开Rtools并导航到bin文件夹. Rtools> bin
3. 在另一个窗口中，打开您的r路径.例如，我的是C:\ Program Files \ R \ R-2.15.2 \ bin \ x64(

1. Download Rtools https://cran.r-project.org/bin/windows/Rtools/
2. Open Rtools and navigate to the bin folder. Rtools > bin
3. In a separate window, open your r path. For example, mine is C:\Program Files\R\R-2.15.2\bin\x64 (more details at CRAN R for windows FAQ)
4. Copy the the Rtools Application "zip" (from 2) into the r path folder (from 3)

现在，您应该可以保存文件了.如果要加载文件，则还需要将解压缩复制到r路径文件夹中.

Now you should be able to save your file. If you want to load your file you'll need to copy unzip into your r path folder as well.
