Your problem might be the space in the file path below ...

>> Sys.setenv(R_GSCMD="C:/Program Files/gs/gs9.05/bin/gswin64c.exe")

... which you could fix as follows (add single quotes around the outside 
so that the file path it itself surrounded by double quotes) ...

Sys.setenv(R_GSCMD='"C:/Program Files/gs/gs9.05/bin/gswin64c.exe"')
