This is the first mention of R/Splus I've seen in this discussion --
for those who don't know, R is the free version of Splus, which is a
very popular language in the academic statistics community. Here's a
longer list of their operator choices from:
http://stat.ethz.ch/R-alpha/doc/html/function.html
%% Arithmetic Operators (base)
%*% Matrix Multiplication (base)
%/% Arithmetic Operators (base)
%in% Value Matching (base)
%o% Outer Product of Arrays (base)
%x% Kronecker Product of Arrays (base)
& Logical Operators (base)
&& Logical Operators (base)
