These two variations without bquote and the third which just replaces
for with while all (that I had previously posted) do work:
# 1
junk<- vector("list",4)
for(i in 1:4) {
junk[[i]]<- eval(substitute(function(x) { 42 + i * x }, list(i = i)))
}
junk

Dang! I had tried using "substitute" before trying "bquote", but hadn't
at that time figured out that I needed to "eval()" the result in order to
get a function rather than a call. Twigged to the need to use "eval()"
while fiddling about with "bquote", and then never went back to
"substitute".
The fact that I don't really understand any of this stuff and am basically
groping around in the dark, hammering and hoping, doesn't make it
any easier! :-)
cheers,
