LDAP binds
I am using 2.0.8. Anonymous binds are no longer supported in the
environment I am using. I need to change my userdb ldap setup to bind. I
believe the ldap server does Kerberos (or can) authentication. My users
are authenticating using Kerberos or Kerberos/PAM. This needs to stay in
place.
Can anyone suggest how I might go about changing my setup to work?
My current ldap setup is as follows (the

Lines between panels in lattice
Hello,
I have a multi-page display each consisting of two-panels above each
other.
I need to draw a line from the top panel to bottom panel. Using
current.vpTree()
i find that "plot1.panel.1.2.vp" and "plot1.panel.1.1.vp" are the top
and bottom ones respectively.
I am using the following code(inspired by Paul Murrell's R Graphics)
to draw a line.

Substituting functions in package - Lattice
Hi,
I'm trying to learn how a package works but substituting a
parituclart function with my own (basically the original one with
some debug statements).
The package is lattice and the method is "print.trellis" which is a
S3 method and is not visible.
To replace this, i sourced a file with the rewritten print.trellis,
and the old one was replaced.
However, i get this error

Crash due to extreme example
Hello,
I was trying this bit of code (i know it is an extreme case)
g=function(r){
if(r==1)
return(list(x=1))
else
return(list(x=g(r-1)))
}
For z=g(500), the code runs but when I print z i.e

I get

Writing a Long across the network?
Hello,
I have to write single Long to a server written in java. The server
passes the input as
in.readLong() // it expects to receive 8 bytes
In Python, i can do it by sending struct.pack( "!q", value)
However, I have tried this
writeBin(length(x),con=conn,endian="big") #conn opened in binary
But the response on the server side is wrong, eg. 1 is received as

Lattice and Axis height
Hello,
My plots consist of 2 rows, 1 column, many pages
I've managed to selectively turn of strips for the bottom panel and
roll my own strip for the top
par.strip.text = list(lines = c(0,3),cex=0.6)
I have my own custom prepanel function too.
What i'd like to do is turn off the x-axis for the top panel (since on

Multidimensional Integration over arbitrary sets
Hi,
I need to integrate a 2D function over range where the limits depend
on the other e.g integrate f(x,y)=x*y over {x,0,1} and {y,x,1}.
i.e \int_0^1 \int_x^1 xy dydx
I checked adapt but it doesn't seem to help here. Are they any
packages for this sort of thing?
I tried RSitesearch but couldn't find the answer to this.
Many thanks for you help.

Waiting for Key input
Hi,
I have another question. Is there any command that waits for key input?
I am running R on OS X, so getGraphicsEvents doesn't work.
I have put some debug print messages in a function and would like to
pause the code every time the message is printed and continue on a
keypress.
Thank you

A question regarding cex and pch="." in lattice
Hello,
I'm using lattice and opened an X11 device with the following call
X11(width=5,height=5,pointsize=1)
I then ran the following code
library(lattice)
x<-rnorm(30,sd=2)
y<-runif(30)
xyplot(y~x,pch=".",col="black",cex=1)
If i remove "cex=1", not all the points are plotted. From ?X11, i

Splitting a lattice stripplot across several pages
Hello,
I have a stripplot with 200+ labels i.e i have network connections.
The y-axis are the server port numbers and am graphing the number of
packets in a connection. Roughly
stripplot(totpacks~portnum,data=network)
Due to the large number of server ports in my dataset, the y-axis
labels overlap so I would like to split it across several panels(1
panel per page) with about 25-50 per

Question on spacing around plot and box in lattice

How can i increase the padding between the axis and the data

An example:

x <- seq(-1,1,length.out=100)
y <- sapply(x,new)

Conditioning variables in lattice - not all combinations
Hello,
I have a shingle A and B. A has 5 levels and B has 4 levels.
Also, I have 8
levels of a factor C. I wish to xyplot( x ~ y | C *A *B,data=data),
I think this is how the lattice conditioning works:
If i'm not mistaken, all possible combinations of C,A,B
, a subset of the data is accordingly taken and x~y is plotted.
However, I
have empty sets for some levels and these are

Set length of axes in lattice
Hello,
It is possible to set the aspect ratio of the Y-axis to the X-axis
in xyplot
(a) xyplot(y~x,aspect=1.8)
Suppose I have only 1 panel and i wish to set the length of the X-
axis to 2" keeping the same aspect ratio as in (a). I would also like
to keep the same scales.
I suppose i need to do something in prepanel but what?
Is there any function i can call to set the actual
