[R] generating phi using function()

[Daniel Nordlund]

The argument 'K' is missing since you are only passing four arguments to 
the phi() function, but you defined it with five formal parameters. It 
looks like the argument 'j' is not necessary in the function.  It is an 
unnecessary carry-over from the summation notation and it is never used 
in the function.
