Rev's Icon & Similarities to the "R" language???

[Richmond Mathewson]

Just had a look at the "R" language manual - and it looks quite
different from xTalk: all one has to do is look at the class of
objects:
I quote:

NULL Null 
symbol a variable name 
pairlist a pairlist object 
closure a function 
environment an environment 
promise  an object used to implement lazy evaluation 
language an R language construct 
special  a built-in function that does not evaluate its arguments 
builtin a built-in function that evaluates its arguments    
logical a vector containing logical values 
integer a vector containing integer values 
double  a vector containing real values 
complex a vector containing complex values 
character a vector containing character values 
... the special variable length argument *** 
any a special type that matches all types *** 
expression an expression object 
list a list    
externalptr an external pointer object 
weakref a weak reference object 
raw a vector containing bytes         
they made my hair go all cute and curly! Not at all like the language "we know and love
so well" [sorry, I grew up on Asterix the Gaul].

further to this:

> e3 <- quote(plot(x = age, y = weight))
     > e3$x
     age
     > e3$y

does not look like any type of xTalk I know:
in fact it looks a lot like the type of computer language
I have spent my level best avoiding.
