I previously could not confirm that the code was misbehaving. but I
now can with on a R version that I installed yesterday with input
through the 64 bit GUI. I do notice that the one time that Dr Azzalini
got an error instead of a crash, the offending call appears similar to
that listed as the most proximate Traceback.
> ask <- function (message = "Type in datum")
+ eval(parse(prompt = paste(message, ": ", sep = "")))
> ask("input")
input: 3:6
[1] 3 4 5 6
> ask("input")
input: c(3,8)
*** caught segfault ***
address 0x0, cause 'memory not mapped'
Traceback:
1: parse(prompt = paste(message, ": ", sep = ""))
2: eval(parse(prompt = paste(message, ": ", sep = "")))
3: ask("input")
Possible actions:
1: abort (with core dump, if enabled)
2: normal R exit
3: exit R without saving workspace
4: exit R saving workspace

You say you are using OS X 10.5.6 but your R.version info says it
is a
Tiger 10.4.11.1 system. Looking at the CRAN package check page I see
that the CRAN build is done on an OS X 10.4.10 machine, which is only
off my one from the 8.11.1 designation, so maybe someone forgot to
update that entry when they updated that machine.
(Your version is even older than mine, so you might try updating.)
Thanks for the feedback and the suggestion. I have then downloaded
the most recent R version 2.8.1 from http://R.research.att.com/
R version 2.8.1 Patched (2009-02-26 r48012)
i386-apple-darwin8.11.1
but the problem with ask() is still there..
R> ask('x')
x: c(1, 3,4)
*** caught segfault ***
address 0x4628d484, cause 'memory not mapped'
In one case, I got instead, withou crash
Error in parse(prompt = paste(message, ": ", sep = "")) :
'getEncChar' must be called on a CHARSXP
Thanks again fro your advice.
Best wishes,
Adelchi Azzalini

If I run exactly the same on a Mac (OS X 10.5.6), it still works
provided R is run in a Terminal window.
The outcome changes if R is run in "its own window", started by
clicking
on its icon; the first two examples are still Ok, the third one
produces:
