[R] increase or decrease variable by 1

[(Ted Harding)]

Indeed!

  x <- x + 1

(and being generous with unnecessary spaces) uses 10 characters.

  `+`(x)<-1

(being mean with them) uses 9. The "mean" version of the first
uses only 6: x<-x+1

However, I suppose there is merit in the spiritual exercise
of contemplating how `+`(x)<-1 gets worked out!
