How to set the root of result file? #74
Description
I find plyrmr very convenient when I deal with matrix on R and Hadoop. However, I have a question. For example, when we merge 2 pipes, like res = merge(a,b), the function will store the result in a temp file like /tmp/file0987987098 and link the res with this file. Can we set the root of file, or know the root of file through any function?(I mean, not through the text information output when we run the merge() ) Thanks a lot!
