change in default behavior of ?functionname in R 2.10?
Hi everyone,
I just installed R 2.10 using the Windows binary. At some point in
the past using the Windows binary installation, the default behavior
of ?functionname changed from plain text to a nice html interface.
Now with R 2.10, the default behavior has changed back to the plain
text help. I assume this has some thing to do with these changes
listed for R 2.10, but I don't quite

I have a problem with read.affy.mixed function. I want to read in

ggplot2, building a simple formula interface
I?m trying to build a simple formula interface to work with a function using
ggplot2. The following scheme ?works? up until the plot(p) request, at which
point there are complaints about xlim?s and a blank graphics window.
Looking at str(p) I do see the limits are NULL, plus layer 1 claims to have

You are right and the problem is solved. Re: about the possible errors in Rgraphviz Package
Hi Martin,
It is really a 'PATH' problem. After adding C:\Program
Files\Graphviz2.20\bin to the 'PATH' environment variable, the
Rgraphviz package can be loaded without any error messages.

for R but not for Graphviz.
Thank you and Duncan so much for your great help.

Hi Gabor,
I just used your R code below and the code worked properly
without any error messages. Attached is the output graph, which
may be the one you expected.
library("Rgraphviz")
set.seed(123)
V <- letters[1:10]
M <- 1:4
g1 <- randomGraph(V, M, 0.2)
g1
plot(g1)
Thanks.
