How to Break Axis in Lattice Plot
Dear All,
I have searched the following problem in the R help achives, and there did
not seem to be solutio for it.
The problem is how to break the axis in the xyplot (lattice plot). I read
the posts using the package plotrix, buy it doesn't work with the xyplot,
which is lattice based.
A simple example is attached below:
xyplot(c(1:10,100)~c(1:10,100))
What I would like to do is

Alignment and Labeling of a color key in a xyplot?
Happy New Year to all R users!
I have two short questions concerning a xyplot with a color key:
1) How do I properly place (align) the color key beside the xyplot?
As you can see from the code listed below, the placement of the color
key is not correct. I would like the upper and lower end point of the
color key to be perfectly aligned with the upper and lower line of
the xyplot. Adjusting

[PATCH] SCRAM-SHA-1 authentication
Hy,
over the last days I have implemented SCRAM-SHA-1 in Dovecot's 2.1
branch. It does not do SCRAM-SHA-1-PLUS, but should be extendable enough
to introduce it later.
There are some checks for the message format which (assuming the client
acts correclty) are not strictly necessary during parsing. This is
partially in the hope that it might aid client implementers, partially
because it (IMHO)

Hello there!
Perhaps this is a little off-topic, but I notice this only on the Centos

metafor and meta-analysis at arm-level
Hi,
I have been looking for an R package which allowed to do meta-analysis
(both pairwise and network/mixed-treatment) at arm-level rather than at
trial-level, the latter being the common way in which meta-analysis is
done.
By arm-level meta-analysis I mean one that accounts for data provided at
the level of the individual arms of each trial and that does not simply
derive the difference between

Lattice: combine the same strip?
Hello R helpers,
I am producing a figure with dual strips, i.e., x~y | S1 + S2, where S1 and
S2 are two strips. For example, in figure 2.1 at
http://lmdvr.r-forge.r-project.org/figures/figures.html.
In this case, I would like to combine the the top strip, since all three
pictures in the same row have the same level based on the first strip. In
other words, instead of
| -- S11 -- | -- S11 -- |

Networking issues with OpenSolaris/Dom0 or VMware Fusion

OpenSolaris (without dom0) the pcn0 interface works just fine but

PHP probes
Hi all,
I remember at OSCON 2005 there was talk of adding DTrace probes
to PHP (in fact, I have a photo of Bryan and Wes working on it!).
Did they ever get into the upstream branch, ''cause I don''t recall
seeing a --enable-dtrace (or similar) configuration option when
I recently built PHP 5.2.1. If not, is there an ETA?
TIA,

grey scale graphs
Hi everyone,
Does anyone know how to get "black and white theme" (grey scale,, I
would say) graphs using lattice or ggplot2, as it is shown in this
webpage: http://lmdvr.r-forge.r-project.org/figures/figures.html?
I am using Sweave, and I cannot get that color configuration.
I have added the following option: trellis.device(color=FALSE) but I got
a pdf file with color graphs.

Lattice: use levelplot as panel for wireframe
Hi,
I want to draw a figure similar to http://dsarkar.fhcrc.org/lattice/book/images/Figure_13_07_stdBW.png
from http://lmdvr.r-forge.r-project.org/figures/figures.html (figure
13.7) . However instead of using a contour plot as a panel for the
wireframe I want to use a levelplot. Can somebody help me with this?
Thanks in advance for any help,
Kind regards,

Non linear modeling
AFAIK most model fitting techniques will only deal with additive errors, not
multiplicative ones. You might want to try fitting:
log(y-x) = a*x + e
which is linear.
