Graph visualization
Hello,
I am working with graph and adjacency matrix, the package 'graph' seems to be appropriate for this.
An example in the package
> mat <- rbind(c(0, 0, 1, 1),
+ c(0, 0, 1, 1),
+ c(1, 1, 0, 1),
+ c(1, 1, 1, 0))
> rownames(mat) <- colnames(mat) <- letters[1:4]
> graph1 <- new("graphAM", adjMat=mat)

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

knitr without R studio
Hello folks,
I`m using knitr on R studio, which make it easy to use, but a coworker of

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

Best way to select good points in a noisy signal ?
Hello,
When I plot y=f(x) from the file xy.txt (
http://www.nabble.com/file/p18773387/xy.txt xy.txt ), I can clearly see a
trend.
Is there a function or a package able to take the median value of y for an
interval of x (x +/- a defined value) to plot nice graph (at least a better
one) ?
Thanks in advance,
Have a nice week-end,
Ptit Bleu.

Must be easy, but haven't found the function (numerical integration)
Hi,
I have a data frame of 2 columns with the following types :
data$day char

And I plot my data with :

type="l")
And I'd just like to get the numerical value of the integration of this
graph.
I looked at ?integrate but, as far as I understood (that is, not very much,

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
suggestions on how you

Strage result with an append/strptime combination

I keep on trying to write some small scripts in order to learn R but even
with basic scripts I have problems ...

Friendly way to link R - MySQL and non-(R and Mysql) users ?
Thanks to your help, I managed to link R and a Mysql Database, send queries,

My co-workers find the job not bad but they would like to have a friendly
interface to send queries and see the graphs (the pdf document is not
necessary).
