Random sampling while keeping distribution of nearest neighbor distances constant.
Dear All,
I cannot find a solution to the following problem although I imagine
that it is a classic, hence my email.
I have a vector V of X values comprised between 1 and N.
I would like to get random samples of X values also comprised between
1 and N, but the important point is:
* I would like to keep the same distribution of distances between the X values *
For example let's say N=10 and

Splitting a data frame into several completely separate data frames
Hello again,
How do I split a data frame into smaller, completely separate data frames
(rather than separate data frames comprising a single "list")? Consider the
following data, and my coding attempt:
x <- read.table(textConnection("id type number
indv.1 bagel 6
indv.2 bagel 1
indv.3 donuts 10
indv.4 donuts 9"), header = TRUE)
closeAllConnections()

Basic question on applying a function to each row of a dataframe
Hi,
I have a function foo(x,y) and a dataframe, DF, comprised of two vectors, x
& w, as follows :
x w
1 1 1
2 2 1
3 3 1
4 4 1
etc
I would like to apply the function foo to each 'pair' within DF e.g
foo(1,1), foo(2,1), foo(3,1) etc
I have tried
>apply(DF,foo)
>apply(DF[,],foo)
>apply(DF[DF$x,DF$w],foo)
However, none of the above worked. Can anyone help ?

How do I...
Only tangentially on topic, at best...
Given a pile of html files, comprising chapters of a book, with a single
html file that serves as a table of contents to the group, how would I
turn the entire book into a single PDF?
I can't think of a way to do that, all I can come up with would result
in a pile of PDFs, one per html. But there's gotta be a better way.
Suggestions welcome.

I need help making a data.fame comprised of selected columns of an original data frame.
I must have missed something simple, but still, i don't know what.
I obtained my basic data as follows:
x <- sprintf("SELECT m_id,sale_date,YEAR(sale_date) AS
sale_year,WEEK(sale_date) AS sale_week,return_type,0.0001 +
DATEDIFF(return_date,sale_date) AS elapsed_time FROM

NULL")

PDF too large, PNG bad quality
...ics{...}' and run the document through 'pdflatex'.
I tried both, creating PNG with 'png(...)' and converting from
PDF to PNG using 'convert' from ImageMagick.
So my questions are:
- Is there a way to produce sufficiently lean PDFs directly in R,
even when the plot comprises several million points?
- How to produce a PNG that still looks nice when included in a
LaTeX PDF document?
Any hints will be greatly appreciated.
Thank you
Lasse

nufa and missing files
We're using gluster-2.0.1 and a nufa volume comprised of thirteen
subvolumes across thirteen hosts.
We've found today that there are some files in the local filesystem
associated with the subvolume from one of the hosts that are not
being seen in the nufa volume on any gluster client.
I don't know how or when this happened, but now we have to do some
work to get this gluster volume

Stacked barplot: specifying individual bar hue/luminance
Hi all,
I'm trying to generate barplots from simple but long (~100000-row) data
files, in which each bar will comprise two stacked 'sub-bars'. All the
upper sub-bars will have the same hue, and all the lower bars will,
likewise, have another uniform hue. However, I wish to specify the
luminance (aka brightness) of each bar (i.e., each whole bar comprising two
sub-bars) separately,

deleting specified NA values
I have a data set of about 10000 records which was compiled from several smaller data sets using SPSS. During compilation 88 false records were accidentally introduced which comprise all NA values. I want to delete these records but not other missing data. The functions na.exclude and na.omit seem to remove all values of NA? How can I delete just the relevant NA's? . i.e. I want to delete

gsub for numeric characters in string
Dear all,
I have what is a bit of a confusing question, so I hope that I can explain
clearly. Thank you for your help in advance.
I would like to do a replacement procedure on several strings, but the way
that I am currently going about it is not working.
I have defined "len", which is a series comprising the lengths of different
items, all preceded by a colon.

Plot table of counts
I have a data set which is comprised of counts, that is, the number of times a mass spectrometer measured a particular mass at a particular time (the rows and columns of the table). Is there a way to make a plot so that it draws a square at the mass/time spot on the graphic if there is a count and leave it empty if it's empty?

selections of data by one variable
Dear R experts,
My problem is as follows:
Suppose I have a data frame d comprising two variable a<-c(1:10) &
b<-c(11:20).
I now want to select a subgroup according the values of b.
I know if I just want to select, say, b=17, I can use f<-d[d$b==17] and R
will give me
> f
a b
7 7 17
However, if now I want to select a subgroup according to b==e<-c(13,15,17),

Generic mixup?
...int
function (x, ...)
UseMethod("print")
<environment: namespace:base>
> showMethods("print")
Function "print":
<not a generic function>
Don''t the two results contradict each other? Or do I have a terrible
misunderstanding of what comprises a generic function?
Thx,

Binary Matrices
I'm wanting to perform analysis (e.g. using eigen()) of binary matrices - i.e. matrices comprising 0s and 1s.
For example:
n<-1000
test.mat<-matrix(round(runif(n^2)),n,n)
eigen(test.mat,only.values=T)
Is there a more efficient way of setting up test.mat, as each cell only requires a binary digit? I imagine R is setting up a structure which could contain n^2 floats.
Thanks in advance

How to comment out entire code parts in Sweave files
Hi,
I am wondering if there is any convenient way to comment out an entire region of
a Sweave file which comprises R and Latex code. Currently I'm doing it for the R
and Latex parts separately or transfer the unwanted part into a different file.
But both are not great solutions. (I am doing this when updating old files and
debugging)
Is there a way to do this with an equivalent of \iffalse \fi or is the...

[LLVMdev] Location of the x86 JIT compiler tool
Hi,
I'm mainly insterested on the x86 JIT compiler.
/lib/Target/X86/README.txt talks about 'Jello', the JIT compiler,
which should be on /tools/jello. I think that changed to /tools/lli
and now comprises a bytecode interpreter as well. Is that right?

An interface can reference multiple zones...
...#TYPE ZONE GATEWAY GATEWAY ZONE
openvpnserver:1194 net 0.0.0.0/0

We want the remote systems to have access to the local LAN - we do that
with an entry in /etc/shorewall/policy (assume that the local LAN
comprises the zone "loc").

Is this "legal"?
