error in plot(table(c('a','a')))
Hi all,
there appears to be something strange with the plotting of tables of 1
dimension; if I attempt to make a plot of a table of characters with only
1 value I get an error (Error in xy.coords(x, y, xlabel, ylabel, log) :
'x' and 'y' lengths differ). With more than one value I don't get
errors, neither with integers (even if only 1 value):

Discriminant Analysis - Obtaining Classification Functions
Hello!
I need some help with the linear discriminant analysis in R.
I have some plant samples (divided into several groups) on which I
measured a few quantitative characteristics. Now, I need to infer some
classification rules usable for identifying new samples.
I have used the function lda from the MASS library in a usual fashion:
lda.1 <- lda(groups~char1+char2+char3, data=xxx)

How to write a Surv object to a csv-file?
Dear All,
trying to write a data.frame, containing Surv objects to a csv-file I get
"Error in dimnames(X) <- list(dn[[1L]], unlist(collabs, use.names = FALSE)) :
length of 'dimnames' [2] not equal to array extent".
See example below.
May be, I overlooked something, but I expected
that also data.frames containing Surv objects may be written to csv files.

Apropos sprintf behavior
If changes to sprintf behavior are being considered, would it
be possible to allow some of the other K&R conversion
specifiers?
xX - for integer to hex conversion, and
c - for ascii value to character conversion
would all be useful for me.
Thanks, Steve Dutky

readLines with space-delimiter?
Hi,
I am reading a large space-delimited text file into R (41 columns and many
rows) and need to do run each row's values through another R object and then
write to another text file. So, far using readLines and writeLines seems to
be the best bet. I've gotten the data exchange working except each row is
read in as one 'chunk', meaning the row has all values between two quotes

R (unix) command line editing for native speakers of vi
As an inveterate user of vi, I was pleased to stumble on how
to use it for editing R commands.
When an interactive R session is launched under unix, the
command line editor most likely defaults to emacs. Typing
<esc>,<ctrl>+j will switch this to vi editing mode (see below
for possible exceptions).
excerpted from readline(3) manpage:

Add support for vhost-user-scsi-pci/vhost-user-blk-pci
Hi Guys,
And I want to add the vhost-user-scsi-pci/vhost-user-blk-pci support
for libvirt.
The usage in qemu like this:
Vhost-SCSI
-chardev socket,id=char0,path=/var/tmp/vhost.0
-device vhost-user-scsi-pci,id=scsi0,chardev=char0
Vhost-BLK

Exclude option not working
Hi ,
Hope you are doing good.
I am Madhavan from India . I was trying to implement the wonderful rsync
concept in my project for file mirroring.
I implemented the functunality but the only problem I am facing is in the *

Though I am trying to exclude the directory by giving proper syntex for
exclude but I find once the whole
rsync is completed the directory still gets

standard naming for components of R data structures
@steve
Seek for online document named "writing R extensions" chapter 2. It tells
how to describe a list structure using item markup for R documentation
files, if indeed this matches your search, thing I am not sure. Something
that looks like...
value{
The \\code{list} owns following names
\\item{alpha}{double vector}
\\item{beta}{integer vector}
\\item{delta}{raw vector}
}

Re: [libvirt] Add support for vhost-user-scsi-pci/vhost-user-blk-pci
Hi Cole & Michal,
I'm sorry for my late response, I just end my journey today.
Thank your response, your suggestion is very helpful to me.
I have added Michal in this mail, Michal helps me review my initial patchset.

All concern about this feature is the XML design.

loop function and integrate?

I have to compute something and i don't know what i'm doing wrong. my code
is a bit complex, but imagine that is something like this:

ia = length(a)
x = seq(1,100,length=0.1)
ib = length(x)
int1 = numeric(ib)
b = numeric(ib)
for(j in 1:ia) {
H = function(x) {sin(x + a[j])}
