Ordering variables in a parallel coordinates plot
Hello all,
I am searching for a way in R to re-order variables before presenting them
in a parallel coordinates plot.
So far I didn't find anything within a R related context on how to do this.
I did find some texts talking about how it should be done in general, here
is such example:

Is it possible to "right align" text in R graphics?
Hello all,
The following line of code includes a right-to-left language text, yet the
R graphics engine displays it from left to right. One problem this causes
is when there are parenthesis in the test, here is a basic example?
plot(1:10, main = "שלום (טקסט)")
Is there a way to make sure the text is displayed from right to left?
Many thanks for any suggestions,

changing the dimensions of a matrix in a real specific way
Hi again,
I'd like to ask you a question again.
I have a matrix like this:
a <-matrix(c(1,2,3,4,5,6,7,8,9,10,11,12))
a
[,1]
[1,] 1
[2,] 2
[3,] 3
[4,] 4
[5,] 5
[6,] 6
[7,] 7
[8,] 8
[9,] 9
[10,] 10
[11,] 11
[12,] 12
Is there a proper way to change the dimensions of this matrix so that I'll get this as a result:

Capturing R console output into a file (sink+savehistory ??)
After reading more, I understand I didn't formulate my last question
correctly, so please allow me to rephrase:
What I am looking for is a way to save the R console session output.
That is, a command that would combine the results of using:
?sink # And
?savehistory
My motivation for this is that doing it will allow someone who is a blind
user of R to be able to easily export his results to

Combining several plots besides a dendrogram?
Hello all,
I would like to recreate the plot shown here (from a useR 2009
presentation):

I downloaded the code for that image, and discovered that it relies on
external web services, and also having PERL installed on the computer.
I believe this could be done "locally" using the "seqLogo"

Windows 7, update.packages problem: "unable to move temporary installation"?

I am using R 2.13.0 with windows 7, after giving my user full privileges to
the R folder (as described

This allows me to install new packages just fine.
However, when using update.packages(), to update existing packages, I keep

Is there a way to have 'comment' keep a list?
Hello all,
I recently discovered the "comment" command.
I see it can only hold a vector of characters.
Is there a way (or an alternative), to make it possible to have it keep a
list?
(for example, to keep different pieces of information like date of creation,
information of each variable and so on)
The closest solution I can think of is using 'names' on the vector, like

bootstrap resampling question
Hello there,
I have a problem concerning bootstrapping in R - especially focusing on the resampling part of it. I try to sum it up in a simplified way so that I would not confuse anybody.
I have a small database consisting of 20 observations (basically numbers from 1 to 20, I mean: 1, 2, 3, 4, 5, ... 18, 19, 20).
I would like to resample this database many times for the bootstrap process with

Why is vector assignment in R recreates the entire vector ?
Hello all,
A friend recently brought to my attention that vector assignment actually
recreates the entire vector on which the assignment is performed.
So for example, the code:
x[10]<- NA # The original call (short version)
Is really doing this:
x<- replace(x, list=10, values=NA) # The original call (long version)
# assigning a whole new vector to x
Which is actually doing this:
x<-
