using reorder in dotplot
Hi,
Please help to correct my error in the following. I want to plot the values
of 'x" in increasing order.
-----------------------------------
library(lattice)
Name<-c("A","B","C")
x<-c(15,20,10)
test<-data.frame(Name,x)
dotplot(Name~x,test)
dotplot(reorder(Name,x)~x,test)
"reorder" has no effect!
Thanks.

dotplot
Hi,I would like to fill the dots in this graph. I would appreciate help to
do that if possible. If fill is not possible, can I make it bright? I do NOT
want to increase the size.

two monitors
Hi, I have set up two monitors. I am using windows XP. I would like to keep
one window- command line in one monitor and the script and graphs in the
second monitor. How do I set it up?
It works for word documents simply by dragging the document. It does not
work if I drag and drop the scripts window. Is R not compatible for this?
Thanks.

Thanks.

cluster function to use with GLM
Hi,In SPlus, I use the function 'cluster' with GLM to adjust for correlated
errors within a cluster ( e.g. cluster(ID)) as a covariate. Is there a
similar function in R to use with GLM ? I am new to R. Thanks.

How to create a line and bar panel chart with two different axes?
I need to create a line and bar panel chart with two different axes. I tried

Statistical mode
One descriptive statistic that is conspicuously missing from core R is the
statistical mode - the most frequent value in a discrete distribution.
I would like to propose adding the attached 'statmode' (or a similar
function) to the 'stats' package.
Currently, it can be quite cumbersome to calculate the mode of a
distribution in R, both for experts and beginners. The lack of a

dotplot (lattice) with panel.segments and groups
Hi,
The following produces almost exactly what I needed. The problems are
that the 'panel.dotplot' call (commented) generates the error 'Error in
NextMethod("[") : argument "subscripts" is missing, with no default'. The
other problem is that the colors alternate between the levels of the 'site'
variable, rather than 'year'.

Dotplot (package Hmisc) with groups: colours and symbols
Hello all,
This question concerns the function Dotplot from the Hmisc package.
My aim is to compare values between groups in each panel of the
Dotplot, with the values of different groups clearly distinguishable
by different symbols. All lines and symbols should be coloured in
black.
Before adding the panel function to the Dotplot, the groups behaved as
desired and were marked by different
