Let P_i denote the true proportion in the ith study and p_i the corresponding

approximately normally distributed

That amount of overdispersion would make the use of a poisson model
very questionable, and will very likely result in estimated standard
errors that are too low, hence the change in statistical significance
when you switch to quasipoisson.

Is there any R plug-in available for Eclipse other than StatET?
StatET doesn't seem to work with the latest release of Eclipse properly,
i.e. syntax highlighting isn't enabled for R commands. I already contacted
the author some time ago, but have not yet received a response.

Here is a function that I have used to write the files on my Windows
machine. I put this function call after each graph that I produce and it
will write out a new file and tell me what the file name is. I can then go
back and copy the files into a document or a PowerPoint presentation.
f.plot
See FAQ for Windows 5.2 and the referenced README.
?win.metafile and ?replayPlot might allow you to replay the saved plot
history (by default in .SavedPlots) into a file in emf or wmf format, I
think, but I haven't actually tried this -- don't know if it will work for
multiple graphs.
Let us
See ?cut for continuous variables, and ?factor, ?levels for the others.

Dear all,
options(graphics.record=TRUE)
can be used to switch the recording on (MS Windows, not sure about other
platforms). See ?options
To set this option as default, use .Rprofile
It is however quite annoying to examine and save all the graphs
manually... You might find functions like postscript(),
The down side to R's factor solution:
The numerical values of factors are always 1 to number of levels. Thus, it
can be tough and requires great care to work with studies that have both
numerical values different from this and value labels. This situation is
currently not well-supported by R.
Dear R-help,
In performing cluster analysis (packages: hopach, cluster, boot, and
many others), I got these errors:

gene.acc)
Error: could not find function makeoutput

Hello,
I tried what you suggested (i.e. combine the separate plot creation
commands into one command from Perl to R), and it worked. The syntax is
as follows:
$R-send(qq (xVal - c(1,2,3,4,5,6)));
$R-send(qq (yVal - c(3,5,2,6,1,5)));
$R-send(qq (c(pdf(C:/Test Environment/R/perlPlotTest.pdf),
I am an R user trying to get around the 2Gig memory limit in Windows, so
here I am days later with a working Ubuntu, and R under Ubuntu. But - the
memory problems seem worse than ever. R code that worked under
windows fails, unable to allocate memory.
Searching around the web, it appears that

Dear all, Is there an R equivalent to SAS's proc format?

Fortunately not. SAS is one of the few large systems that does not
implicitly support value labels and that separates label information
from the database [I can't count the number of
