R help - Jan 2008 - is it safe to replace every "<-" by "=" in R code?

hi;

When I first started looking at R code, I thought that the <- notation for 
assignment made the code less readable (and I still do).  Then I found that 
now one can use "=" in place of "<-" for assignment (I
understand this
started since version 1.4). Anyway, I think using "=" makes the code
much
more readable.

I was wondering, would it be safe if I replace all the occurrences of
"<-"
by "=" in any function of R? Or do you think this will break things?

I like to look at a pretty code, and I just can't stand looking at those 
"<-" any more :)

I am using latest version of R on windoz platform.

thanks
Nasser

No.

but if you only replace it in the context:

x <- ...

then it should be ok.

.. and don't forget that 6 -> x works but 6 = x won't ...
