¿Alguna explicación para este fenómeno? (Relativo al uso de memoria)
Hola, ¿qué tal?
Tengo un df relativamente chiquito:
> dim(loans)
[1] 15172 22
> object.size(loans)
7488144 bytes
Sin embargo,
empresas <- split(loans, loans$number_id)
length(empresas)
#8748
object.size(empresas)
# 50643907728 bytes
Es decir, el objeto resultante de partir un df de 15000 filas en 8700
dfs ocupa 5GB.
¿Alguna idea de por qué ocurre esto?

Interesante... y preocupante.
No propuso alguien, no hace mucho, reescribir R desde el principio por
este tipo de cosas?

¿Alguna explicación para este fenómeno? (Relativo al uso de memoria)
Hola, ¿qué tal?
Al final he descubierto el motivo del problema. Cierto que esperaba
cierto nivel de _overhead_, pero nunca tantísimo. Por mucho _overhead_
que haya, no se pasa de 7MB a 5GB.
El problema era que (a pesar de mi opción stringsAsFactors = F) los
niveles de los factores se copiaban íntegros en cada una de las
columnas de tipo factor de cada una de las tablas resultantes. Aunque

Hola, ¿qué tal?
Lo que quieres es un "debugger visual" (como el de muchos IDEs,
incluyendo Netbeans y Eclipse) para R, como el de Revolution,

Pues sí, efectivamente, existe, pero solo con la versión de

Javier,
R también tiene opciones de "debug" como la que estás comentando.
Te adjunto un ejemplo práctico:

Bootstrap error message: Error in statistic(data, origina l, ...) : unused argument(s) ( ...) [Broadcast]
I quoted the relevant part of the documentation for you. Have you actually
try to read what it says?
Sure, you don't get any error, but have you checked whether any
bootstrapping was actually done? Most of those functions are generics, thus
having the "..." argument that can take anything. Doesn't mean they will be
used. See if the following helps:

survfit is too slow! Looking for an alternative
Hi All
I found survfit function was very slow for a large
dataset and I am looking for an alternative way to quickly get the predicted
survival probabilities.
My
historical data set is a pool of loans with monthly observed default status for
24 months. I would like to fit the proportional hazard model with time varying
covariate such as unemployment rates and time constant variables at loan

Setting up shares with multiple directories
Morning everyone.
Have a quick question on what would be the best way to set up sharing for
my instance.
Our samba server is going to be hosting applications that are used by our
clients everyday. On our Samba server, I have setup the directories like
this: (I should mention, one of our applications will have multiple folders
to hold the corresponding data)

How do I test a unique index?
I have a loans table and a payments table. Each loan has_many payments.
So far no problem.
Now, the payments table has a payment_number field, and each payment has
a payment_number unique within that loan. For example, Loan A can have
payment_numbers 0, 1, and 2 and Loan B can have payment_numbers 0, 1, 2,
and 3 (but only one of each payment_number). I can enforce this with a
unique index in

apcsmart and dual environmental sensors
Hi,
We have a several AP9612TH environmental cards (they have 2 probe
connectors) inserted into our APC UPS devices which monitor temperature
and humidity. The apcsmart nut module knows how to query the
ambient.temperature and ambient.humidity using the 't' and 'h' commands
of the UPS (refer to apcsmart.h). The results of the 't' and 'h'
commands are from probe 1.

find()ing rows w/ NULL columns?
Agile Web Development with Rails doesn''t seem to have NULL in the
index [or my eyes have failed me again], and web searching turns up
lots of SQL statements containing NOT NULL.
I have a table of loans, and I want to record when something was
loaned and returned. The loan date can''t be null, or there''d be
no entry in the table. The return date must be something

controlling panel.width and panel.height in viewports
Dear all,
I'm trying to get a series of lattice levelplots to appear in
viewports in a particular way but struggling to exert fine control
over their appearence. There are two conditions: (a) I only want the
levelplot to appear (I don't want axes, colour key, etc) in the
viewport and (b) I want the levelplot to expand to the maximum
allowable space in the viewport while observing

GLM/GAM and unobserved heterogeneity
Hello,
I'm interested in correcting for and measuring unobserved
heterogeneity ("missing variables") using R. In particular, I'm
searching for a simple way to measure the amount of unobserved
heterogeneity remaining in a series of increasingly complex models
(adding additional variables to each new model) on the same data.
I have a static database of 400,000 or

Administrator account: For Windows 2000 and Samba
I know i've asked this before, but I was unable to get a clear response on
how this works exactly.
As I said before: The Administrator account on Windows machine is there by
default.
My question is, can I add a Administrator account to samba and make sure
they are part of the Domain Admins group to ensure that I can still use the
administrator account to do certain functions on my clients

help with push
Hi, sorry if I misunderstood everything...
In the file src/gallium/drivers/nouveau/nv30/nv30_screen.c there is loans of
PUSH_DATA which is basically *push->curr = data;
I'm thinking that somehow push->curr is the bo->map = drm_mmap(...)
that is called in nouveau_bo_map. But I cannot see how they are linked...
Because when nouveau_bo_map calls nouveau_bo_wait

Question on LDAP+Samba+PDC
Hello everyone.
Well, I have been working very hard lately, trying to get a server up to
act as our Samba PDC with LDAP. So far, everything seems to be working
well. I've been able to get samba 2.2.8 and openldap 2.0.27 installed with
no problems. I've setup my config files (ldap.conf, slapd.conf, smb.conf)
as well as added some initial entries to the LDAP directory.

Select updates database?
I am running on Rails 2.2.2 on Solaris (and also on my mac) against
mysql. For some reason, when I use a select in the partial, the
database does not get updated with the changed value. I am using
checkbox for other fields which works perfectly.
I can provide more information if needed, but I would like the field
to work as a dropdown instead of a text field.

Migrating Profiles: Revisited

Well, i've tried to figure this out on my own by asking questions and

User directories and groups usage
Morning everyone.
I was playing around today with our PDC setup.
One thing I noticed is that when I setup users to have their 'My Documents'
directory be /home/<user> everything works well.
One thing I noticed is that the directory, subdirectories and files have
the owner of the user and the group as per assigned, and permissions as 700.
If I wanted to set it up so a specific
