Running R on read-only file system, without temporary directory
Dear All,
I would like to do run R without having write permissions to any
directory on the system. It seems that I need to modify the R source
code for this, to make R start without creating a temporary directory.
So far, so good. But should I expect any more complications? Does R
really need the temporary directory that much?
Thanks,
Gabor

snow and different R versions
Dear Luke and others,
I have many R versions on my machine and want to start a particular
one when snow builds its cluster. (The same version I start snow
from.) It seems that everything is set up correctly in
defaultClusterOptions:
> mget(ls(defaultClusterOptions), defaultClusterOptions)
$homogeneous
[1] TRUE
$manual
[1] FALSE
$master
nodename
"maya.unil.ch"

question about SNA in R, thanks!
Dear colleagues,
I'm trying to have a look at the Assortative and Disassortative (
http://en.wikipedia.org/wiki/Assortative_mixing) of the network I have.
But it seems that the igraph hasn't mentioned that yet.
I have to get the in/out degree of the vertices of each edge and calculate
the Pearson's Correlation coefficient which seems to be quite a huge task
for me. :(
So I wonder if

Curved arrows
I'm trying to draw an arrow with a curved shaft on the graph as a straight
one looks messy on a detailed graph. I've looked in arrows but it doesn't
seem to give an option. larrows doesn't look much more promising. I had a
look in the archive and couldn't find anything. Any thoughts?
Thanks

random numbers between 0 and 1
Hi,
To generate random numbers between 0 and 1, do you use rnorm followed by dnrom? for ex, for 10 variables
a = rnorm(10)

pickle in R
Hello all!
I was wondering if there is a way to pickle an R object into a file
like it is possible in python? Such as you have an complicated R
object(not a dataframe) , you use a function to write it to a file and
than you have a function where you can retrieve the object from that
file later on.
Thanks

Rd.sty question: LaTeX expert needed
The Rd.sty LaTeX package is used when building the R manuals, and by the
LaTeX pages produced from the man pages.
I have tracked down some problems G?bor Cs?rdi was having recently (see
"Re: [R] preformatted and '#' in manual pages" in R-help) to a LaTeX
problem, and am trying to work out how to fix it.
Specifically, the .Rd file he was using had a structure like

Conditional rows
Hi,
Given a simple example, test <- matrix(c(0.1, 0.2, 0.1, 0.2, 0.1, 0.1, 0.3,
0.1, 0.1), 3, 3)
How to generate row indexes for which their corresponding row values are
less than or equal to 0.2 ? For this example, row 2 and 3 are the correct
ones.

network
Hello
I am a relatively new user of R and am struggling to use the 'network' package. I have a correlation matrix (produced using 'cor'), and want to draw a network where each item showing correlation above a threshold (say 0.5) is joined by a green line, and each item showing correlation below a threshold (say -0.5) is joined by a red line. Does anyone have any hints of how to

Minimum Spanning Tree
Hi all, I'm very new to R and read a few tutorials, however I'm having
difficulty trying to figure out how to plot a minimum spanning tree. I have
a csv file that contains an n-by-n matrix of distances between strains of
bacteria called matrix.csv.
Looks like:
id,strain1, strain2,strain3
strain1,0,.2,.8
strain2,.3,0,.7
strain3,.4,.6,0

re placing values in a matrix
useR's,
Consider:
y <- c(20, 25, 30)
> m <- matrix(c(0.0,1,NA,0.5,1.25,0.75, 0.5, NA,
> NA),byrow=TRUE,nrow=3,ncol=3)
> m
[,1] [,2] [,3]
[1,] 0.0 1.00 NA
[2,] 0.5 1.25 0.75
[3,] 0.5 NA NA
For each numeric value, I want to replace them with their corresponding
y-value. The result should look like (here, each row represents a variable
rather than the columns):

I'm offering $300 for someone who know R-programming to do the assignments for me.
There are six assignments in total. It won't take you long if you were
familiar with R. For those who are interested, please send me an email
with your profile (your experience with R, how long and how often have
you been using it.) I will be paying through paypal. Thanks!

preformatted and '#' in manual pages

I have the following in a .Rd file:

human readable (not binary) format. The format itself is like
the following:

Here, the first vertex of an edge is preceded with a pound sign

Count unique rows/columns in a matrix
Dear List,
i know there are some solutions for this in the archive,
but they're not very good for numeric matrices, since they
usually convert rows/columns to character strings. Is there
an easy way to do $subject for numeric matrices properly,
or i need to do it by hand?
