Cluster analysis question
Hello All,
I have data where each feature data point is a vector, and my distance
measurement is a weighted dot product between vectors.
I would like to use R to perform a cluster analysis on this data. Does
one of the R cluster analysis routines provide for a user provided
distance function?

Slightly OT: Generators & UPS
Hi,
Can anyone shed some light on this:
My PC's are on a separate power circuit. Each PC has its own UPS.
I have an old Honda generator. When the power goes out, I fire up the
generator. However, the UPS's still run on battery. If I connect the
PC directly to the socket and bypass the UPS, the PC works.
I was told by a UPS supplier, that the power output from the
generator was

mgcv, gam
Hola!
I have some problems with gam in mgcv. Firts a detail: it would
be nice igf gam would accept an na.action argument, but that not the
main point.
I want to have a smooth term for time over a year, the same pattern
repeating in succesive years. It would be natural then to impose
the condition s(0)=s(12). Is this possible within mgcv?
I tried to obtain this with trigonometric terms, aca:

(Fwd) Re: Slightly OT: Generators & UPS
Hi,
I'm the original poster on the subject.
Thanks for all the replies.
A few more points.
The generator outputs 7kw @ 220V.
The total PC's supplied is about 9.
I estimate power consumption to be
9 x 300w=2700w
4 halogens @ 400w each=1600w
10 Compact Flourescents @ 11w =110w
Therefore total power=4410w
Which leaves me with spare capacity of about 2590w (in theory).
I think its

interactive file choosing in Linux?
I am used to using the [R] function choose.files() for interactive file selection in MS-Windows.
What is the comparable function in Linux? I expected the function file.choose() to display similar behavior, i.e., a graphical interface diplaying a file listing, but all I seem to get is a "text input prompt". This does not seem correct.
> file.choose()

Time conversion from Win32 64bit FILETIME?
Windows-32 has a time structure called FILETIME, a 64-bit value
representing the number of 100-nanosecond intervals since January 1,
1601 (UTC). That is not a typo, the year is 1601.
Does anyone have a clue(or algorhithm)for how this is converted to
something a little more POSIX-like ?
Thank you,
Derek

To make it clear, this is EPEL-5. There was some still unresolved
problem with adding a dependency on KVM:

As a result, we have to depend on qemu (software

[PATCH v19 3/7] xbitmap: add more operations
This patch adds support to find next 1 or 0 bit in a xbmitmap range and
clear a range of bits.
More possible optimizations to add in the future:
1) xb_set_bit_range: set a range of bits.
2) when searching a bit, if the bit is not found in the slot, move on to
the next slot directly.
3) add tags to help searching.

Lattice / Trellis analog of axis(graphics) ?
My question is so basic that I am (almost too) embarrassed to admit that
I could not find an answer after an hour's worth of homework.
What is the Trellis / Lattice analog for the axis(graphics) function
that enables the creation of axes in locations other than the default
(i.e., bottom for X axis and right for Y axis) ?

Disabling Password authenitication with SSH
Hello everyone,
We are setting up a server at work, and we have run into something that
I am not sure how to resolve.
We have set up sshd (OpenSSH server) on the machine. We have placed ssh
keys into each user's home directory that needs to access the system
(and they work). We want to disable everyone from logging in, using a
password, utilizing ssh keys only to access the system.
