R functions dump and save can be used to save any R objects into files. Use ?dump and ?save to find out how to use them. Please list the similarity and difference of dump and save functions. Create a few R objects (more than one object) and dump (and save) them into (two separate) file. Find a way to rename dumped (saved) objects. Then use R function source (and load) to source (load) the file you just created. Again use ?source and ?load to find out how to use them. Check if you get the same R objects back (need to compare renamed R objects with ones sourced (loaded) from a file.
