please do not use several commands in one line. This makes it difficult 
to decide which output belongs to which command.

Loading the library RSAGA and its dependencies seems to work.

Hmm, the problem could be, that RSAGA was build _before_ SAGA GIS 2.0.7 
was installed? In this case try to rebuild and reinstall RSAGA under R, 
please.

You also could try to work with SAGA GIS 2.0.8. If you decide to change 
to the newer version, please also reinstall RSAGA _after_ installing
