Hello Everyone! NULL replacement will change expression object into list:
>
> te <- expression(a=23*4, b=33-2)
> te
expression(a = 23 * 4, b = 33 - 2)
> te[["a"]] <- quote(blabla) #ok
> te
expression(a = blabla, b = 33 - 2)
> te[["a"]] <- NULL #change to list
> te
$b
33 - 2
I am on w32, version 2.11.1 (2010-05-31)

Vitally.
