If I use the "open in editor" or "Open recent", R will hang. If I use load(file.choose()), it shows this error:

You shouldn't try to load() a .R file.  It is a source file; you would 
use source() to read and execute it.  load() is for binary images of 
workspaces, typically called something like .RData.
