In addition to the previous remarks, you would do yourself a favour by utilizing the implicit-none option of gfortran. That will force you to declare every variable (and its type) which will avoid many nasty bugs. In your case: x is a REAL single precision but with R you will preferably need double precision. So I would advise you to use gfortran -fimplicit-none ......
