drawing the graph with many nodes
Good morning,
I'm trying to draw a graph, and I'm using the following code.
test.matrix<-read.table("~/Desktop/Results/testgephi.csv", header = T,
sep=",")
colnames(test.matrix) <- gsub("X", "", colnames(test.matrix))
#drop first column
drops <- c("")
test.matrix<-test.matrix[,!(names(test.matrix) %in% drops)]

Plotting with Rgraphviz
Hi All,
After a lengthy battle just to get the package installed, I am not able to
actually use Rgraphviz to generate any plots. I tried just using the sample
code in the documentation
(http://www2.warwick.ac.uk/fac/sci/moac/people/students/peter_cock/r/rgraphviz/)
and I get the following:
*> > library(Rgraphviz)
> test.matrix<-matrix(rep(c(0,1,0,0), 9), ncol=6, nrow=6)

Nodes & edges with similarity matrix
Hello,
I apologise if someone has already answered this but I searched and
googled but didn't find anything.
I have a matrix which gives me the similarity of each item to each
other. I would like to turn this matrix into something like what they
have in the graph package with the nodes and edges.

Concatenate xyplots
Dear R-community,
I created 5 different xyplots and graphed all of them with the print command on one page (e.g.
print(graph1, split=c(1,1,1,5), more = T)
... print(graph5, split=c(1,5,1,5), more =T)
Using the above commands separates each graph by a white space. However, since the graphs do share the same x-axis, I was wondering if there is a way to concatenate graph1 through 5 so

Graphics device history recording problem (Previous and Next utilities)
I use 1.7.0 version under Windows XP.
Problem:
When graphics device history recording function turned
on, suppose I source a file containing lines:
plot(graph1)
plot(graph2)
I see the graph2 in the graphic device, assuming
graph2 is the last plot in the file. Now using
"Previous" under history menu, I get graph1 as
expected. But after that, using "Next" does not show
graph2.

How to include CI in a grouped barplot?
Hello everyone!
I need to include the confidence interval bar in a grouped barplot. I've
found some options on the web, but none of them solved my problem.
The question is: my barplot was created using vectors for each pair of bar
and them combining them using cbind.
I mean:
a=c(10,15)
b=c(20,24)
c=c(21,23) ...
hei=cbind(a,b,c)
graph1=barplot(hei, beside=T,...)

frequency of labels in a barplot
I'm trying to control the number of labels in the x-axis of my plot. My code
is the following:
graph1<-barplot(total_skew)
axis(1,at = graph1,labels=raw_date[1:length(total_skew)], las=2)
however, the length of my "total_skew" parameter is a few thousand elements,
and all the labels on the x-axis are overlapping and cluttered. How do I
specify the frequency or number of labels

Problem between panel.abline and log scales (lattice)
Hello and Happy New Year to all R-Users !!!
I would like to plot a lattice graph with a logarthmic y axis and add two
reference lines that is :

knitr without R studio
Hello folks,
I`m using knitr on R studio, which make it easy to use, but a coworker of
mine would like to run it on "simple" R. So I was wondering if you know what

Clogit or LRM?
Hello
I believe that I'm getting very close in my modeling application.
I've come across a challenge that I am unable to solve and would really
appreciate the group's opinion.
I've been using the val.prob function from the Design library (Thanks
Frank!!) to both evaluate and visualize my model.
From the scores and graph, it appears as my model is very accurate in

help: trouble using lines()
Hi R experts,
I have been using ReML as follows...
model<-lmer(late.growth~mtf+year+treat+hatch.day+hatch.day:year+hatch.day:treat+

then I wanted to plot the results of the three way interaction using

Finding a path using the Graph package
Hello,
Does anyone know of a way of finding all the nodes that are between a pair
of specified nodes in the excellent graph package (R vers 2.5.0).
I have a class(graphAM) object and need to determine all possible pathways
in this object.
Here's an example: In the simple case of a--b--c (where -- denotes
"conected to") the list of all pathways would be: ab ba abc cba cb bc.

qplot and for loops
I have 4 columns and 56 rows of made up data that I want to plot as a series
of bar graphs. The idea is to create one bar graph for each of the 4 columns
using a for loop. I tried the following command in RStudio and when I type x
in the console I get just the 4th graph instead of all four graphs. I did
not define what x is before hand. I was not sure what it would be. Any

I represent a graph as an adjacency matrix of class "dgCMatrix" (from the Matrix package).

a fix for rotated PDF graphs
Hi,
I have found references for the following problem in the list
archives, but no nice solution. So I decided to post one I came up
with.
The problem is that graphs output as eps files, for example using
ps.options(onefile=FALSE, paper="special", width=8, height=8,
horizontal=FALSE, pointsize=12)
get rotated when I convert them to pdf using epstopdf. Both ghostview

Sweave: Avoiding recompilation of figures
Hello everybody out there using Sweave,
There are some complicated SQL queries and laborous calculations against large data included as R code chunks using Sweave in my LaTeX document.
These code chunks create graphs that do not change most of the time, but they are of course recompiled every time I run Sweave on my file for update of minor changes to the LaTeX text.
Is there an option

Combine R2HTML and Rcmd BATCH?
Hi All,
I have an R script that spawns output in the form of an HTML page. This

Now I want to run the same script using Rcmd BATCH. However, it seems
that it is not possible to use R2HTML in this case.
My script ends with this error message:

testing the contents of an environment
Suppose I want to delete everything in my working directory that is not
a function. It seems that
sapply(ls(),is.function)
always returns FALSE, because ls() returns objects of mode character.
How do I evaluate is.function(), not on a character string, but on the
object that character string represents?
Thanks,
