From: Kjetil Halvorsen
Subject: as.list
I don't understand the behavior of "as.list"
(really as.list.default) on arguments which
are expressions. An artificial example:
> as.list(expression( x <- 1, y <- 2))
[[1]]
<-
[[2]]
<-
as.list.default contains the following code:
if (is.expression(x)) {
l <- vector("list")
for (sub in x) l <- c(l, sub[[1]])
--- why the sub[[1]] part?
eliminating the [[1]], I get:
> my.as.list(expression( x <- 1, y <- 2))
[[1]]
x <- 1
[[2]]
y <- 2
