## Logical AND ("&&") has higher precedence than OR ("||"):
- 
 
 68 
TRUE || TRUE && FALSE   # is the same as
- 
 
 69 
TRUE || (TRUE && FALSE) # and different from
- 
 
 70 
(TRUE || TRUE) && FALSE

## Special operators have higher precedence than "!" (logical NOT).

 73 
## You can use this for \%in\% :
- 
 
 74 
! 1:10 \%in\% c(2, 3, 5, 7) # same as !(1:10 \%in\% c(2, 3, 5, 7))
- 
 
 75 
## but we strongly advise to use the "!( ... )" form in this case!

## '=' has lower precedence than '<-' ... so you should not mix them
- 
 
 79 
##     (and '<-' is considered better style anyway):
-

## Consequently, this gives an error

try( x <- y = 5 ) #->  Error in (x <- y) = 5 : ....
