strange sprintf() behaviour ?
This is quite strange behaviour - at least for R-novice as myself....
Consider this:
> testf <- function() { x <-2; sprintf("%s %f", "x =", x); return(x) }
> result <- testf()
> testf <- function() { x <-2; sprintf("%s %f", "x =", x) }
> result <- testf()
> testf()
[1] "x = 2.000000"

ordering levels
Hello!
I would like to know if there is a simple way to reorder levels of a given factor.Let's say that the vector
testf<-factor(c("red","red","red","blue","blue","white"))
levels(testf) : blue red white
should have reordered levels such as
levels(testf) : red blue white
(this is for presentation purposes)
I guess

problem accumulating array within a function over loops
Dear R helpers,
I am having trouble with an array inside a loop.
I wish to accumulate the results of a function in an array within
the function, over several loops of a program outside the function.
The problem is that the array seems to re-set at every entry to the
function. Here is an example, so you can see what I mean.

[LLVMdev] mixed bc file
I have a question with llvm-gcc and llvm-gfortran.
Is it possible that llvm-ld can combine different bc files compiled from C programme and Fortran Programme together?
For example:
Compile a c program into llvm bc file by the task:
# llvm-gcc -emit-llvm test.c -c -o test.bc
and then compile a fortran program into llvm bc file by the task:
# llvm-gfortran -emit-llvm testf.f -c -o testf.bc

Sorry, sorry....
of course
levels(testf)[c(2,1,3)]

parallel processing with multiple directories
Hello,
I would like to run some code in parallel with each cluster reading/writing to a different working directory. I've tried the following code without success. The error I get is: "Error in setwd(x) : cannot change working directory"

ordering levels: I was wrong
I was wrong about needing the Relevel from the Lexis package.
The default verson of relevel does the job of reshuffling levels
in any desired order, albeit with a warning (which comes from the
fact that apparently only a single number had been anticipated by
the designer):
> testf <- factor( sample( letters[1:4], 100, replace=T ) )
> table( testf, newf=relevel( testf, ref=c(3,2,1,4) )

combine_factor to empty level
ID: T8dfe471e360ac80264c6c
Dear,
I'm using R 2.8.1 with the package reshape version 0.8.2 .
It seems that the combine_factor function has problems with combining levels to
an empty level:
#EXAMPLE WORKING
test<-sample(c(1:10),1000,replace=T)
testf<-factor(test, c(1:10), LETTERS[1:10])
table(testf,exclude=NULL)
testc<-combine_factor(testf, c(1,1,1,1,1,2,2,2,2,2))

relevel expansion suggestion
To the R developers,
The discussion below reminded me that I think it might be a good idea
to take the Relevel function from the Lexis package and replace relevel
in stats with it. This is really nothing special for epidemiology.
It is fully compatible with the existing relevel (it actually contains
the
relevel code almost verbatim as a subset), but it has the extra
functionality
of combining

how to list clones for a snapshot
Hello,
Is there a way how to list all clones for given snapshot of a file-
system ?
e.g. I have the following snapshots:
local/testfs at sunday
local/testfs at monday
local/testfs at tuesday
and clone local/tuesday of local/testfs at tuesday. Now I''d like to get
local/tuesday using
local/testfs at tuesday as input.

cbind alternate
I have two one dimensional list of elements and want to perform cbind and
then write into a file. The number of entries are more than a million in
both lists. R is taking a lot of time performing this operation.
Is there any alternate way to perform cbind?
x = table1[1:1000000,1]
y = table2[1:1000000,5]
z = cbind(x,y) //hanging the machine
write.table(z,'out.txt)

access objects
hi,
say I have consecutively numbered objects obj1, obj2, ... in my R workspace.
I want to acces one of them inside a function, with the number given as an argument.
Where can I find help on how to do that? Somebody must have been trying to do this before...
Some keywords to start a search are appreciated as well.
Here's an example, I hope it clarifies what I'm trying to do:

features of save and save.image (unexpected file sizes)
Hi,
Today I came upon unexpected R behaviour. I did some modelling and the
result was R object, about 28MB size (nested list, with matrixes as
list elements). When I was saving the session with save.image, the
resulting .RData file was 300MB. There were no other large objects:

question: how to select a column from a dataframe in a function
Hi,
I am creating a function and ran into the problem of selecting a column
from a dataset. It seems as though the $ function (as in data$columnname)
does not apply in the function. In simplified version:
This works:
testf2<-function(data,columnnumber){print(data[,columnnumber])}
But this doesn't:
testf<-function(data,column){print(data$column)}
Even though the first solution works,

lustre quota problems
...a given value (e.g. the values which
are provided in the operations manual), I''m able to write exact the amount
which is set with setquota.
But when I delete the files(file) I''m not able to use this space again.
Here is what I''ve done in detail:
lfs checkquota -ug /mnt/testfs
lfs setquota -u winnie 307200 309200 10000 11000 /mnt/testfs
Now I wrote one single big file with dd.
dd if=/dev/zero of=/mnt/testfs/test
As expected it stops writing the file after it is ~300 MB large.
Removing this file and restarting dd leads to a zero-sized file, because

How to bypass failed OST without blocking?
Hi
I want my lustre do such things during OST failed: if some file
has stripe data on th failed OST, any operation on the file will
return IO error without blocking, and also at this moment I can
create and read/write new file or read/write files which have no stripe
data on the failed OST without blocking.
What should I do ? How to configure?
thanks!
