#### 1.18 Saving and Loading R Data Objects
 In situations where a good deal of processing must be used on a raw dataset in order to prepare
 it for analysis, it may be prudent to save the R objects you create in their internal binary form.
 One attractive feature of this scheme is that the objects created can be read by R programs
 running on different computer architectures than the one on which they were created, making it
 very easy to move your data between different computers. Each time an R session is completed,
 you are prompted to save the workspace image, which is a binary file called .RData in the
 working directory.
 
<p>
 
 Whenever R encounters such a file in the working directory at the beginning of a session,
 it automatically loads it making all your saved objects available again. So one method for
 
 saving your work is to always save your workspace image at the end of an R session. If you
 would like to save your workspace image at some other time during your R session, you can use
 the save.image() function, which, when called with no arguments, will also save the current
 workspace to a file called .RData in the working directory.
