I have made a list in which each element is a function. If I print

hidden?
Hi Mik. I see the same behaviour as Bert, not what you see.
Generally the comments will be shown if the "srcref" attribute is
attached to the function, and it is a valid one. That shouldn't change
between looking at flist[[3]] and flist[3]. If it's not there or not
valid, you'll see a deparsed version of the function; that's what your
flist[3]$btv looks like.
It's possible this is R 3.3.2-specific; that's a relatively old version
now, but I don't know of any change that would cause this. Can you show
us the code that you used to create flist, or enough of it to show this
behaviour? Showing us (or me privately) dput(flist) might be enough to
see what's going on.

flist[[3]]
function(y,brackets,rates){
# Calculates before-tax income required to realized value y
ints<-c(0,cumsum(diff(brackets)*rates[1:(length(rates)-1)]))-brackets*rates
x<-(y+ints)/(1-rates)
x[sum(x>brackets)]
}
flist[3]
$btv
function (y, brackets, rates)
{
ints <- c(0, cumsum(diff(brackets) * rates[1:(length(rates) -
1)])) - brackets * rates
x <- (y + ints)/(1 - rates)
x[sum(x > brackets)]
}
I am running R 3.3.2 on Mac OS X 10.10.5
