Hadley asked about the Blue book; my shelf still has the earlier brown book
    Becker and Chambers, 1984, S: An interactive environment for data analysis and graphics.

The manual page for precedence is

$               component select
%x              special operator
-               unary minus
:               sequence operator
^ **            exponentiation
* /             mult/div
+ -             add/sub
< > <= >= == != logical
!               not
& |             and/or
<- ->           assignment
