passing arguments via "..."
I would like to do something like the following:
Fancyhist<-function(x,...) {
# first, process x into xprocess somehow, then ...
if (is.null(breaks)) { # yes, I know this is wrong
# define the histogram breaks somehow, then call hist:
hist(xprocess,breaks=breaks,...)
} else {
# use breaks give in calling argument
hist(xprocess,...)
}
}

How to overlay a global map on a filled contour?
I would like to plot some lat-lon data in a filled contour, and then
overlay a map of the globe on top. I am trying something like this:
filled.contour(lons, lats, glb.data,
plot.axes={axis(1);axis(2);map(projection='rectangular',parameters=0,add
=T)}
)
The filled contour plots fine, and the map shows up, but only as a very
tiny little black rectangle in a small area of the

vectors on top of contours, and lattice
OK, I needed to plot a set of vectors on top of a contour plot. I
figured out a way to do this. I create a panel function that calls
"larrows()" with arguments constructed from my vector data. Then, when
I go to do the contour plot, I call contourplot() with the "panel"
argument set to point to my newly created panel function.
So far, so good.
Now, I need to do a

FW: fairly simple file I/O
OK, my apologies. I am sure this is a question that has been answered
before. But I have looked all over the web and can't find an answer for
it. I promise, wasting your time and bandwidth is my last resort.
So here goes:
I have an ASCII file formatted like so:

Label 1.2
Array of data from time 1

need help with ordering of plots
I want to do a series of contour plots, 4 in all. The data is coming
from a data frame named "nd.frame", which has elements "xdf", "ydf",
"zdf", and "pndt". I am treating "pndt" as a factor, and it has four
levels. I make a call to the lattice graphics routine "contourplot"
like so:

(hopefully) simple array op
I have a multidimensional array "a", for example,
> a
, , 1
[,1] [,2]
[1,] 1 3
[2,] 2 4
, , 2
[,1] [,2]
[1,] 5 7
[2,] 6 8
So a is 2x2x2.
I have another array "b", for example,
> b
[,1] [,2]
[1,] 9 11
[2,] 10 12
So b is 2x2.
I want to "tack" b onto a so that b becomes a new "plane", so to speak,

weird error with contourplot
Sorry if I am cluttering up this list with too many rank beginner
questions. But I *am* a rank beginner, and I am at my wit's end with
this one:
I have a data frame df, with components x,y,z. This command to make a
contour plot with lattice graphics works just fine:
> contourplot(z~x*y,data=df,cuts=20)
Then I try
> contourplot(z~x*y,data=df,cuts=20,region=T)
And it dies on me with

adding blocks to arrays
I have a four-dimensional array. I have a three-dimensional array I
want to add to it. My particular problem is conceptually very simple
because the new array is just going to go into the end of the 4D array;
i.e. will be added into the final index. I think I have seen an R
command that can do this in one shot, but for the life of me, I can't
find it again. Am I making this up, or is there

JavaGD package
Am trying to install package JGR and, by necessity, JavaGD on a few
Linux platforms. R rev. 2.14.0. Had some success on one platform, but
am running into a problem on a new platform. I installed rJava, JavaGD,
iplots, and JGR. Things went - I thought - without a hitch. Now, when
I try to use JGR, I start R and issue the command "library(JGR)" and get

configure can't find readline -- but it's there!
Am trying to install 2.14.0 on a CentOS system. The configure script
apparently can't find something to do with the readline library:
Configure: error: --with-readline=yes (default) and headers/libs are not
available
Yes, I know I need readline 4.2 or later. "yum" assures me that rev 5.1
is already installed.

integrating multi-dimensional dat along one dimension
I just want to integrate a 3D data set along one dimension to obtain a
2D data set. Something like:
(given array "d" with dim nx,ny,nz ...)
data_int<-array(dim=c(nx,ny))
for (n in 1:ny) {
for (m in 1:nx) {
data_int[m,n]<-sum(d[m,n,])
}
}
The thing is, given R's facility with integers, it seems that I should
be able to obtain data_int without the

troubles installing R
I am trying to install R on a pretty up-to-date CentOS system. I have
tried installing 2.14.0 and 2.13.2. In both cases, the configure step
fails, and does not produce a Makefile. So, of course, I can't issue
"make".
The errors that I can find in config.log are, first, several missing
files: ac_nonexistent.h, minix/config.h., readline/history.h, and
readline/readline.h.

adding variable to netCDF file
I would like to open an existing netCDF file and add a variable to it.
I am using the ncdf package. This test code gives the idea of what I am
trying to do:
library(ncdf)
print('here we go')
print('first, construct netCDF file')
t<-dim.def.ncdf('t','',1:1,unlim=T,create_dimvar=F)

file input with readLines
I am using readLines to read a fairly large ASCII file. readLines reads
a fixed number of lines, then other R code processes the data, then
readLines reads the same number of lines again, then other R code
processes the data, then ....
Sort of like:
conn<-file('filename','r')
for (chunk in 1:100000) {
Lines<-readLines(conn,n=25)
# process "Lines"
}

We have serveral RHEL 3.0 Update 2 servers running Samba.
These have been working flawlessly for several months..
Recently, the base upgraded all the Windows 2000 servers

NOTE: we don't have admin rights to the Domain Controllers.. (wish we did..)
Previous to the Domain (and kdc) controllers to 2003 we had

SAMBA and SMB Signing
Hello,
We're working on setting up a SAMBA server, but it is not working.
There is a standard configuration for our Windows Vista machines. With
the previous configuration of Windows Vista ("Alice") it connects to the
SAMBA fine. However, the latest Windows Vista configuration ("Bob")
will contact the SAMBA server, send the required password then just stop
communicating.

Need Help Getting Windows XP To Use Samba Properly
Hi everyone, new to the list.
My apologies if this issue has already been covered, but I am having the
following problem with Samba:
Using Windows XP as a client, I am trying to see a Solaris system as a
server. Solaris is running Samba 2.4.2, and Windows 2000 sees it as a
server without any problems.
Windows XP, however, generates the error "The network name is no longer

Tripplite_usb
He everyone,
I have a Tripplite SMART700DVa using the tripplite_usb from NUT 2.5 (rev
2217) driver running in Solaris 10x86. My driver hangs when trying to
connect. Once the driver sends the watchdog command ("W\0"), it can no
longer receive any signals and eventually exits. The UPS responds to
other watchdog commands ("W5" for example), but there doesn't seem to be

SUN_LIBUSB
Hi all,
I've been trying to get a TrippLite 700DV communicating with nut in
Solaris. The problem was that I would successfully send a message to the
ups, but wouldn't be able to receive anything. After some snooping
around I found this bit of code in libusb.c libusb_get_interrupt().
