Hi everyone,
I am new to Linux and R - but I managed to build R-2.5.1 from source to use
it in Genepattern. Genepattern does only support R-2.5.1 which I could not
find anywhere for installation via apt-get or in the Ubuntu Software-Centre
(I am using Ubuntu 14.04 (Trusty Tahr) 32-bit)
But after d

I'm not sure I understand your question. Both functions return "" "CD" ""
because they perform exact string matching. The first demonstrates how string
or character replacements can be vectorized, while the second merely
demonstrates how Rcpp can accelerate this type of operation.
Cheers,
Adam

Thanks Dave.
What I actually want is to obtain say 10, different sets of (n=50) data for
every 10,000 iterations I run. You will realise that the current code produces
one set of data (n=50). I want 10 different sets of 50 observations at one run.
I hope this makes sense.

Dear All,
I am performing some simulations for a new model. I run about 10,000 iterations
with a sample of 50 datasets and this returns one set of 50 simulated data.
Now, what I need to obtain is 10 sets of the 50 simulated data out of the
10,000 iterations and not just only 1 set. The model i

This is very basic. Have you made **any** effort to learn R -- e.g. by
going through an R tutorial? If not, please do this before posting
further. This will save you -- and foks on this list, probably -- a

Hi Adam,
Possibly subset() or & would be helpful. Or even aggregate(),
depending on your ultimate goal.
Without a reproducible example that includes some sample data provided
using dput() (fake is fine), the code you used, and some clear idea of
what output you expect, it's impossible to figure o

I'm on RHEL 6.6, R version 3.2.1 Patched (2015-07-30 r68761) --

does not complete. A window is partially drawn then freezes.
Does anyone know of a solution?

Hello R-help,
I am trying to compute the mean of a quarterback's career fantasy football
stats, but I wish to exclude his 2014 stats from the mean, as that will be
the test data for the model I am trying to build for my academic undergrad
research.

Thanks David,
I was hoping for something a little bit more generic and less
case-by-case basis.

Daniel,
Basically just responding to your last paragraph (the others are
interesting, but I think that you are learning as much as anyone and I
don't currently have any other suggestions).

should learn more about them if you cho

Martin,
I think the main problem is that you are trying to assign your results
to the result matrix inside the foreach loop. Parallel functions in R
are generally not good at updating parts of matrices from the different
workers in this way. Instead, using e.g. foreach, each loop of the

Dear all,
when I am running the code attached below, it seems that no results are
returned, only the predefined NAs. What mistake do I make?
Any comments and help is highly appreciated.
Thanks and best,

Hi April,
You need nested loops for something like this

D.mat<-SE.mat<-matrix(NA,nrow=nrows,ncol=nqs)

Thank you very much to you both for your help.
I knew that parallelizing has some additional "overhead" costs, but I was
surprised be the order of magnitude (it was 10 times slower.) Therefore I
thought I made some mistake or that there is a more clever way to do it.
Best,

Thank you very much for your help.
I tried it under Unix and then the parallel version was faster than under
Windows (but still slower than the non parall version). This is an important
point to keep in mind. Thanks for this.
Best,
Martin
