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.

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
is the equivalent of the button "knit HTML" in RStudio in R. I tried

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

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

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

R: plotting multiple functions
Hi all
Another simple question.
I would like to plot three graphs one the same plot with different
colours. Say red, blue and black. Here are the functions.
r1<-1+5*cos(2*pi*seq(1:100)/20)+rnorm(100)
r2<-1+7*sin(2*pi*seq(1:100)/20)+rnorm(100)
r3<-1+7*sin(2*pi*seq(1:100)/20)+5*cos(2*pi*seq(1:100)/20)+rnorm(100)

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

+ c(0, 0, 1, 1),
+ c(1, 1, 0, 1),
+ c(1, 1, 1, 0))

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

prediction error in ROCR package when sampled y consists of only one class
Dear R users,
Hi. I am using prediction function in ROCR package.
y consists of two classes 0 and 1.
However, since I am using cross-validation, a sampled small number of
y may consist of only one class

In this case, prediction function gives an error:

set.seed and for loop
Dear All,
This is hard to describe so I made a simple example.
set.seed(1001)
total <- 0
data <- vector("list", 30)
for(i in 1:30) {
data[[i]] <- runif(50)
}
Let's call a data set runif(50).
While the for loop is running, 100 data sets are generated.
I want to restore 23th data set (the data set generated in 23th for
loop) without the loop.
I've tried set.seed(1023)

Multiple plots in one window
Dear All,
I made a function which gives 3 plots in one window(I used
par(mfrow=c(1,3)) in the function).
Using that function 3 times, I want to produce 9 plots in one window.
I tried par(mfrow=c(3,1)) or par(mfrow=c(3,3)) but it didn't work.
For example,
pf <- function(p) {
par(mfrow=c(1,3))
plot(c(p:(p+10)),c(1:11))
plot(c(p:(p+10)),c(2:12))
plot(c(p:(p+10)),c(3:13))
}
