Hola usuarios, Necesito detectar si existe o no un cambio de tendencia y si dicho cambio es significativo, para una serie temporal del tipo AirPassengers, en la que a partir de un determinado momento se ha hecho una campaña (supongamos que una promoción de vuelos). Para ello he pensado varios métodos: Usar la descomposición espectral de la muestra [decompose(AirPassengers)] y luego una Regresión

I ran a function called BoxCox, taken from the book by Venables and Ripley, for checking the need for power transformation. This function works fine using the version 0.50 of R, but gives an error message with version 0.60. The lm function in version 0.60 is different from that in version 0.50. Is there a bug in the new lm function? Kung-Sik Chan >

hi guys, i have some trouble in creating lagged variables to use as external regressors. i'm trying to use lag(x) but it gives me as result the same time series (x), adding this part at the end: attr(,"tsp") [1] 0 2323 1 where do i wrong?are there other functions to be used? thanks sara -- View this message in context:

Hi We have a legacy app and i need to find *libg++.so.2.7.2.8 in a package for CentOS 4.5 - I can only find this library in a package for RH 7.x and this cane be installed as it conflicts with stuff from compat-libstdc++-296 which we also need.* ** *Any ideas ?* ** *thanks* **

Hello, This is the little basic program I used to test xattrs. First thing I did was something like this cd /mnt/btrfs-test for i in $(seq 0 100000); do touch file_$i; done and then run time ./xattr-test /mnt/btrfs 0 time ./xattr-test /mnt/btrfs 1 time ./xattr-test /mnt/btrfs 2 the 0 test creates 100 xattrs for every file in the directory. the 1 test just does a listxattr for every file in

Hi Folks, Alright, so I'm figuring out how to embed from the various docs and other nuggets of hidden information, and I've managed to get a nice little C++ framework going which is supposed to make working with R embedded stuff much easier. The problem is, R likes to define things that other libraries also like to define. For example, the libg++-v3 library has a macro called

I want to generate a list (called "dataList" below) where each of its levels is named. These names are assigned to nameList, which contains all possible permutations of size two taking letters from a larger alphabet, e.g., "aa",...,"Fd",..,"Z1",... One of these permutations is the character string "NA". It seems that when I try to name one

Hi, I have tried to load a file originally from Excel, via csv, text and clipboard today. When I succeed I cannot change the format from "factor", and when I try to convert it to numerical it only gives the position of the "factor-group", not the real value in the column? Any quick suggestions? Andreas [[alternative HTML version deleted]]

hello, how can take the string in the data frame. right now i have a table that create as a data frame and stored in the file called "data.xls" and now i want to read data frame as a table in my another r program, i used the following command: the first column of the data frame is just one number called "num", but the second one a list of string, called "name". d

I am trying to define subset operator for a reference class and hitting some problem i am unable to diagnose.To give an example, here is a toy class generator that is a wrapper around a list tmpGEN<-setRefClass("TMP", fields=list( namelist="list" )) tmpGEN$methods('add'=function(obj, name){ namelist[[name]]<<-obj })

Though tapply(x, factor, fun, simplify =TRUE) should be equivalent to sapply(split(x, factor), fun, simplify=TRUE), note simplify=TRUE, it is not so if fun() returns a vector rather than a scalar, e.g. > tapply(1:6, c(0,0,0,1,1,1), function(x) c(min=min(x), max=max(x)), simplify=TRUE) $"0" min max 1 3 $"1" min max 4 6 > sapply(split(1:6, c(0,0,0,1,1,1)),

ROracle ploblem I can't install ROracle in the window XP. Is there any way to install ROracle package on the windows OS ? I think I can enhance data acquisition performance using oracle native dirver instead of using ODBC. Tae Sik Han. North Carolina State University.

Hi, I noticed that brctl (or more accurately, libbridge) is using the wrong path when doing various lookups in sysfs: e.g. /sys/class/net/brXXX/stp_state when it should use /sys/class/net/brXXX/bridge/stp_state. This doesn't cause any problems on most systems as it falls back to the ioctl when the sysfs attempt fails; however the ioctl method is apparently deprecated. I believe the

I'm switching from OpenLDAP to the newly released Fedora Directory Server (formely known as the Netscape Directory Server) as a LDAP backend for my Samba domain. I'm now faced with a problem regarding how Fedora DS handles the userPassword field. Unlike OpenLDAP it encodes it in base64 so instead of reading userPassword: {SSHA}0lP+r3Z1NVan7Caf4CG9oSgnTbQRrv/p it reads: userPassword::

Hi am a newbie to mongrel. am using mongrel cluster in my ruby application. When i start mongrel cluster it is working fine and when i stop it it says already stopped port 8000. it is giving the error as follows ********* simple selection ********* ********* selection by list ********* -A all processes -C by command name -N negate selection -G by real

summary: The function 'by' inconsistently strips class from the data to which it is applied. quick reason: tapply strips class when simplify is set to TRUE (the default) due to the class stripping behaviour of unlist. quick answer: This can be fixed by invoking tapply with simplify=FALSE, or changing tapply to use do.call(c instead of unlist executable example:

First, here's the problem I'm working on so you understand the context. I have a data frame of travel activity characteristics with 70,000+ records. These activities are identified by unique chain numbers. (Activities are part of trip chains.) There are 17,500 chains. I use the chain numbers as factors to split various data fields into lists of chain characteristics with each element of
