R help - Dec 2010 - increase or decrease variable by 1

many languages have shorthands for that operation like:

variable += 1
or
++variable

is there something like that in R ?

You can do this:
> x <- 3
> `+`(x) <- 1
> x
[1] 4

x+1 is not that complicated... Am I missing something here?

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!
