Probably not, actually.
Because they are the norm on Windows
That's why I hate them!
R is set up to cope
with them and I chose to have my Macs set up with the stanadard file
systems so I'm more likely to see problems if they occur.
The only time I have ever seen an issue was the no-segfault.R tests
creating a file PACKAGES and stopping a directory Packages being
created.
My little contretemps in respect of .RData and .Rdata
is somewhat related. And this was caused by my fumble-fingering
and then, when I discovered my fumble, wondering why an error
***didn't*** occur.
As I understand it Rolf was unaware that he had a case-insensitive
file system and so was surprised.
Yep. That is correct.
That's very understandable, and
I've seen it with some new Mac users here -- but they seem to get used
to it.
I guess I *can* get used to it. :-)
cheers,
Rolf
The problems I encounter are the other way around: users assuming
everything is case-insensitive and e.g. documenting 'R CMD install'
and 'R CMD CHECK' .I had assumed these were Windows users, but I now
realise that there may be Mac users who habitually ignore case.

I think you should check whether reformatting is really
necessary. My
understanding is that Disk Utility will allow repartitioning and
one can
choose a disk format at the time that a new partition is created.
Not clear to me what you're saying here. Are you suggesting that
I (could)
partition my
hard drive into a chunk containing the current file system and a
new chunk
(with
nothing --- yet --- written on it)? And that I could choose a
disk format
for
the new chunk such that the file system would be case-sensitive
there?
But then I'd get case sensitivity only when working with files
stored in the
new
chunk, is it not so?
Sounds dangerous to me, anyhow!
I don't have much of an understanding of file systems and
partitioning, I'm
afraid.
cheers,
Rolf
