Is this a Windows system behind a firewall?
Can you reach the CRAN mirrors directly from Internet Explorer?
If yes to both, then you need to use
setInternet2(TRUE)
before doing the package installations from the RConsole menu.
See the Windows FAQ and the ?setInternet2 for more details.

Hi,
We have some tight controls in our systems and I am having difficulty
downloading/upgrading R packages. The IT department will configure our
system to let me download packages from two or three R depositories.
How do I find out what the IP address of the R depositories are so that

Perhaps it would help to remember that dotted quad notation is
shorthand for an integer value. If an IP address is a.b.c.d, you can
also represent it as a*16777216 + b*65536 +c*256 +d.
If you can convert IP addresses to and from integers then it should be
trivially easy to find the bounds of the
Hi all,
Sorry, David has just told my that it was a mistake in my example (Thanks
David). I had a wrong idea.
The right idea is: make a ip range, when the number increament without an gap
(and with maximum number: 255, see example down).
In case my initial example would be:
> 162.131
Hi Peter,
I hope you could help. I am stuck with this. The last problem I have is:
I have table like:
id rank color status ip
138 29746 yellow yes 162.131.58.1
138 29746 yellow yes 162.131.58.2
138 29746 yellow yes 162.131.58.3
138 29746 yellow yes 162.131.58.4
138 29746 yellow yes 162.131.
Thank you Peter,
This solved the problem.

Suggest you be more specific. The solution I posted does handle missing values
sorting them to the beginning:
> Lines <- "id rank color status ip

A quick fix could be to substitute "..." or "0.0.0.0" for the "NA"
entries. (Use something like
ipch <- as.character(df$ip)
ipch[is.n
Hi,
Unfortunately, they can't handle NA. Any suggestion? Some row for Ip don't have
ip address. This cause an error/ wrong result.

Feel free to use my code however you want. If you put in a package I
prefer an LGPL license, but not required. See R documentation on how
to create a package.

Maybe you can make a package for something like this. (IP sort,etc). Like in
Perl, there is a module called Sort::Key::IPv4
I think, not only me has the same problem for sorting e.g IP?

Thank you guys. I will use the hb2 , because it is the fastest one.

Not really, just the old saying that any piece of code can be made
twice as fast (which often holds true recursively). /Henrik

i think peter's code is more r-elegant, though less generic. here's a
quick test, with not so surprising results. gsubfn is implemented in r,
not c, and it is p
Here is yet another way:

Hi VQ,
Thank you. It works like charm. But I think Peter's code is faster. What is the
difference?

Hi,
Is there any way to sort a tabel with a colum with IP-address?
table:
