Sliding a Window in R
Dear all,
I am having a vector of around 300.000 elements and I Want to slide fast a window from the first element until the last-Windowsize
what I have so far is the following for statement:
for (i in 1:(length(data[,1]) - windowSize)) {
out[i] <- mean(data[i:(i + windowSize - 1), ])
elements[i]<-length(i:(i + windowSize - 1))
}
but this of course takes ages to

GPS handling libraries or (String manipulation)
Dear all,
I would like to ask you if R has a library that can work with different GPS formats
For example
I have a string of this format
N50° 47.513 E006° 03.985
and I would like to convert to GPS decimal format.
that means for example converting the part N50° 47.513
to 50 + 47/60 + 513/3600.
Is it possible to do that with R?
What is the name of such a library?
I would like to thank you in

Sum two Vectors of different length
Dear all,
in one part of my code I want to sum two vectors element-wise
the problem is that either the 1st vector or the 2nd vector always have one or two less elements
example of my problem

ist kein Vielfaches der Länge des kürzeren Objektes

Plot Many Data to same plot
Dear all,
I have a function that for a variable number of inputs plots them to the same plot
I am doing this quite simply by

How to call a function defined within another function
Dear R-users,
I would need some advices on the proper way to call a particular function.
This function is called scope.char and it is embedded in the step.gam
function from the gam package. I am trying to call scope.char directly in a
script but I did not find the proper way to do so. Is this even possible? If
so, what is the proper syntax?
Thank you for your time and help.

Powerful PC to run R
Dear all,
I'm currently running R on my laptop -- a Lenovo Thinkpad X201 (Intel Core
i7 CPU, M620, 2.67 Ghz, 8 GB RAM). The problem is that some of my
calculations run for several days sometimes even weeks (mainly simulations
over a large parameter space). Depending on the external conditions, my
laptop sometimes shuts down due to overheating.
I'm now thinking about buying a more

NAMESPACE file generation issue R 2.14.0 on Debian Squeeze
When I did install.packages("sqldf") on Windows and Mac OSX, it installed
fine.
However, when I did it on my Debian Squeeze box under R 2.14.0, it failed.
I discovered that three of the dependent packages, chron, proto, and
gsubfn, do not include a NAMESPACE file in their distribution tar.gz files.
I contacted the developer, who told me that, for packages without a

Reading multiple .csv-files and assigning them to variable names
Hi all,
I've been trying to find a solution for the problem of reading
multiple files and storing them in a variable that contains the names
by which I want to call the datasets later on.
For example (5 filenames):
- The filenames are stored in one variable:
filenames = paste(paste('name', '_', 1:5, sep = ''), '.csv', sep = '')
- Subsequently I have

Time unit in ts() and arima() functions
This question is surely trivial, sorry. I'm afraid I'm misunterpreting
the information I got with the documentation, and I'm a little bit
confused. I'm just an engineer with some little skills in statistics.
Well, I have a time series - 600 days long - with some weekly
periodicity inside. So far, so good.
Well, if I define the time series with, say :

Missing objects using dump.frames for post-mortem debugging of crashed batch jobs. Bug or gap in documentation?
Dear R friends,
to allow post-mortem debugging In my Rscript based batch jobs I use
tryCatch( <R expression>,
error = function(e)
{
dump.frames(to.file = TRUE)
})
to write the called frames into a dump file.
This is similar to the method recommended in the "Writing R extensions"
manual in section 4.2 Debugging R code (page 96):

How to catch warnings

Adding a clang commandline option to change backend behaviour
Thank you all for your suggestions!
@David, thanks for the advice, I'll check MCOptions again and look into LLVMContext.
@Craig, @Aaron, great suggestion, moving the option away from CommandFlags.inc to a more appropriate file and adding an extern declaration to the corresponding header gives me more flexibility and allows me to invoke the option by using -mllvm. From my current

Sample covariance matrix in R
Hello everyone.
I would like to find the sample covariance matrix using R.
So far I read on the wikipedia what a sample_covariance is
http://en.wikipedia.org/wiki/Sample_covariance
according to wikipedia one vector is enough to calculate the sample covariance matrix.
In R I tried cov(myvector) and I get the reply that I need to pass either two argument or one matrix with x,y values .
How can I

Extract
Base R. Regarding code improvements:
1. Personally I find (\(...) ...)() notation hard to read (although by
placing (\(x), the body and )() on 3 separate lines it can be improved
somewhat). Instead let us use a named function. The name of the
function can also serve to self document the code.
2. The use of dat both at the start of the pipeline and then again
within a later step of the pipeline

Multiple Assignment built into the R Interpreter?
Dear R Core,
working on my dynamic factor modelling package, which requires several
subroutines to create and update several system matrices, I come back to
the issue of being annoyed by R not supporting multiple assignment out of
the box like Matlab, Python and julia. e.g. something like
A, C, Q, R = init_matrices(X, Y, Z)
would be a great addition to the language. I know there are several
