I think simple R question
I have a vector x with #'s ( 1 or -1 in them ) in it and I want to
"mark" a new vector with the sign of the value of the a streak
of H where H = some number ( at the next spot in the vector )
So, say H was equal to 3 and
I had a vector of
[1] [2] [3] [4] [5] [6] [7] [8] [9] [10]
1 -1 1 1 1 -1 1 1 -1 -1
then, I would want a function to

a series of 1's and -1's
Does anyone know of a simple test
in any R package that given
a series of negative ones and positive
ones ( no other values are possible in the series )
returns a test of whether the series is random or not.
( a test at each point would be good but
I can use the apply function to implement
that ) ?
thanks.

Help me replace a for loop with an "apply" function
...if that is possible
My task is to find the longest streak of continuous days a user participated
in a game.
Instead of writing an sql function, I chose to use the R's rle function, to
get the longest streaks and then update my db table with the results.
The (attached) dataframe is something like this:
day user_id

R newbie example code question
Sometimes I print out a package
and read about it and there
are sometimes nice examples
that I would like to run myself.
Is there a way to bring them
into R from the package or
are they only meant to be typed
in manually ? If manual is the
only way, that's fine. I was
just checking whether there was
a quicker way. Thanks.

R newbie configuration
I think I did enough reading on my
Own about startup ( part of the morning
And most of this afternoon )
to not feel uncomfortable asking
for confirmation of my understanding of this startup stuff.
Obviously, the startup process is more complicated
Than below but, for my R newbie purposes,
It seems like I can think of the startup process as follows :

newbie R question
I'm sorry to bother everyone with a stupid
question but, when I am at an R prompt in Windows,
is there a way to see what packages
you already have installed from the R site so
that you can just do library(name_of_package)
and it will work.
I've looked at help etc but I can't find
a command like this. Maybe there
isn't one which is fine.

.Rprofile files (was R newbie configuration)
Thanks a lot. setHook is

But it's great to save these
Thing so I can look them up
When I feel more comfortable.
Just to add to that Stata versus R discussion :
I believe, anyone who uses
any other package than R, is probably missing
out in the long run. It's truly unbelievable
what has been done here. I feel like I

customising installed libraries
hello
I am returning to some libraries that I had previously customised by amongst
other things adding additional functions. I had simply typed these new
functions into the file in library/R/thelibrary. These however do not seem
to be loaded now as they previously were under older versions of R.
What's changed and what do i need to do?
Thanks

Determine longest run of number
Does anybody know a way to determine the longest run of a number in a
vector of numbers?
For example if I have the following numbers: 0 0 1 1 1 1 0 1 1 0 0 0 1
1; how can I determine that the longest run of 1's = 4 and longest run
of 0's = 3?
Thanks,

Fonts do not display properly on Red Hat
Hi
I'm using R version 2.3.1 on Red Hat Enterprise Server 3.
When I run a simple:

The plot comes out great, but the fonts are displayed wrongly:

I realise this is probably not an R problem per se, but before I go
messing about with my fonts, can someone tell me which fonts R (or X11)

[LLVMdev] RFC: GLIBCXX_DEBUG ScheduleDAG Patch
Attached is a patch to fix a GLIBCXX_DEBUG error in ScheduleDAGRRList.
The problem is that calls to CapturePred may reprioritize elements in the
priority queue, violating streak weak ordering requirements.
To fix this, I introduced a reference wrapper for containers to obtain access
to the SUnitVec used by std::priority_queue. When CapturePred runs, it
calls updateNode which does a

Blasphemous? any support for a REPO of current edition BIND, et al (e.g., BZ561299)?
Hello CentOS Community Members,
What is RH's be-all end-all justification for staying with an ancient
code base for such important programs as BIND et al?
A similar problem (to BZ561299) was first reported five (5) years ago
on the isc.org mailing list.
Is there any support among the CentOS community for a REPO of current
vintage for such important functions as BIND et al?

Optimizar código
Hola lista, tengo una base de datos muy grande de un datalogger.
Consiste en un vector con 0's y 1's, y tengo que ver cuando hay 600 o
más unos seguidos. Se me ocurrió hacerlo con un loop for. Pero tarda
demasiado. También intente usar which para que seleccione solo los 1
para empezar a sumar pero no hay gran diferencia. A alguien se le
ocurre alguna solución para hacerlo más rápido?
