Bind together two vectors of different length...
Dear everyone,
I've got difficulties in realizing the following
task:
I have two vectors:
A <- c(1:10)
B<- seq(1,10,2)
Now I want to make a table form vectors A and B as rows, and if a value of A
isn't present B, then I want to put a N/A symbol in it:
Output should look like this:
1 2 3 4 5 6 7 8 9 10
1 0 3 0 5 0 7 0 9 0
How can I do this in R?
Thank you.

Indexing vector with repeated values
Hi all,
I have a vector which contains many repeated values.
>Z <- c(1,2,3,4,5,1,2,3,4,5,1,2,3,5,5,2,3,4,5)
I need to know how many times each number in this vecetor is repeated.
I can use a command like this:
> table (cut(Z,seq(1,5,1)))
(1,2] (2,3] (3,4] (4,5]
4 4 3 5
But how can I find a break points for vector with random values and random
number sequence

R: "biplot" graphical options?
Thanks Andris, Michael and Petr for your prompt and kind feedbacks.
I will try generating my own biplot from low-level graph commands... I hope it will work.
Best regards,

Greek symbols in xtable rows
Dear R-helpers,
I am using xtable package to prepare a Latex code of some R tables.
Is this possible to have a greek symbols in xtable cells?
How can I get for example a string of : $\Delta$
> "$\Delta$"
[1] "$Delta$"
And string: > "$\\Delta$"
[1] "$\\Delta$"
Gives a latex aoutput like: \$$\backslash$Delta\$
Thank You in advance

Get "home" directory and simple I/O
Is there any generic function that gets the "home" directory? This
should return /home/<user> in Linux and
x:/Documents and Settings/<user> (or whatever) in Windows XP.
Another (unrelated) question: what is the _simplest_ way to
read and write R variables to/from files such that they are
stored in a human-readable but R-like form? For example, if
(say), x is a vector

For loop indicies
I would like to run a for loop with an index going from 0 to 499 but the following seems to miss out the first value:
C <- 499
for (i in 0:C)
The alternative is:
C <- 500
for (i in 1:C)
{
#Then every time I use i, I replace it with i-1
}
Is this a good way to do it or is tere a better way?
Thank you,

memory.size help
I keep getting the 'memory.size' error message when I run a program I have
been writing. It always it cannot allocate a vector of a certain size. I
believe the error comes in the code fragement below where I have multiple
arrays that could be taking up space. Does anyone know a good way around
this?
w1 <- outer(xk$xk1, data[,x1], function(y,z) abs(z-y))

Interactive plots with R

At this example i have a three samples and i want to zoom through x and y
axis to compare differences between samples. With my script below I can zoom
to some data region and add some other spetra to the plot, through text input

Fwd: dovecot bug report (64 bit file offsets)
I have found similar problem:
http://www.dovecot.org/list/dovecot/2007-January/018623.html
"After configure remove HAVE_PREAD from config.h, recompile and see
if it works."
I think I figured out where might be the problem. If the binary is
compiled in the 64bit environment and you want to use 64 bit file
offset you must use 64 bit equivalents of the function. Of course if

question about dataframe ("sensory") in PLS package
Dear all,
I am trying to my dataframe for the PLS analysis using the PLS package.
However I have some trouble generating the correct dataframe. The main
problem is how to use one name to represent several columns in the
dataframe.
The example dataframe in PLS package is called "sensory". I cannot
directly read the data file since it's a binary file. If I use

Clustering large data matrix
Hello,
I have a large data matrix (68x13112), each row corresponding to one
observation (patients) and each column corresponding to the variables
(points within an NMR spectrum). I would like to carry out some kind of
clustering on these data to see how many clusters are there. I have
tried the function clara() from the package cluster. If I use the matrix
as is, I can perform the clara

Start and Restart R over SSH
Hi,
I have some big calculations in R to be done.
Since I can use R on a server with ssh, i was wondering if I can reopen
a R Shell after exiting ssh.
I don't want to use the batch mode and nohup doesn't work.
I want to use something like
ssh user at server

close ssh but let R remain on the server, doing the calculation

FW: Kernel
Doug,
I remove ed config from rc.conf and system boots up without any error
messages. When I try to config interface manually (ifconfig ed0 ***) then
I saw it again. Is it ifconfig problem?

data structure for plsr
All,
I am working with NIR spectral data and it was great to find that the example in ?plsr also used spectral data. Unfortunately, I am having difficulty figuring out how the "yarn" dataset is structured to allow for the plsr model to read:
library(pls)
data(yard)
yarn.oscorespls <- mvr(density ~ NIR, 6, data = yarn, validation = "CV", method = "oscorespls")

Exporting objects plotted with plot3d() - rgl package
Dear all,
Can anybody tell me how to export a 3d figure made with the plot3d
function? I'm careless about whether it's still interactive or not in
another format, as long I can get it out of R.
Thanks!

Formatting numbers
I've been trough the R documentation for about half an hour and it's not
clear to me how to do this:
I need to format to character a series of integers from 1 to 1000, and I
like them to look like
"0001" "0002", "0059", "0123" and so on. Padded with zeroes to have four
digits.
Cheers!

unlicense
Unfortunately, our lawyers say that they can't give legal advice in
this context.
My question would be, what are people looking for that the MIT or
2-clause BSD license don't provide? They're short, clear, widely
accepted and very permissive. Another possibility might be to
dual-license packages with both an OSI-approved license and
whatever-else-you-like, e.g. 'MIT |
