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.

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)

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.

More than one series in a coplot
Hi!
I would like to know, how do you plot more than one data series when
using "coplot"?
I think I know the answer if "plot" is being used:
x <- 1:10
y <- 1:10
y2 <- 1:10* 1.1
plot ( y ~ x, type="n" )
points( y ~ x, type = "b", col = "red" ) # plot the points and lines
for the first series

coplot and par
R 1.9.1 on Win2000 or Win98SE.
I am using coplot as follows:
coplot(AVG~LRPI| REGION)
the output seems normal but I get:
"Warning message:
calling par(new=) with no plot"
This is the only explanation that I have for being unable to use par() with
coplot for changing the way the xlab and ylab appears. From within coplot I
can change the text itself but not the font, fontsize, etc,
