I like the fact that in subtracting two time series objects that there is some effort to align the series. So if I have a time series of that begins at 1 and one that begins at 2 a subtraction operation makes sure that the proper values are subtracted. But I am unclear as to the best way to build a time series with "holes". say that I have data for "day" 1,2,6,7 in one time

Estimados usuarios-de-R: Tengo un problema. Si por ejemplo tengo una lista conformada por la serie historia del PBI de 10 paìses. >Tiempo <- seq(1:100) >plot(Tiempo, PP$"Serie 1", type="l",col="1") >lines(Tiempo, PPcapita$"Serie 2") >lines(Tiempo, PPcapita$"Serie 3") >lines(Tiempo, PPcapita$"Serie 4")

Can someone shed some light on this obscure portion of the help for lm? "Considerable care is needed when using 'lm' with time series. Unless 'na.action = NULL', the time series attributes are stripped from the variables before the regression is done. (This is necessary as omitting 'NA's would invalidate the time series attributes, and if

I could use some advice regarding xyplot. I've got 2 time series. Both cover approximately the same period of time (ie, 1940 to 2009). But one series has annual data and the other has monthly data. One refers to university enrollment; the other to unemployment rates. Both are currently in the same data frame. I'd like to use the monthly times series as a light grayscale background for a

I wish to draw a graph representing multiple series (sets of x,y points). Each series has its own label and points within each series are joined by a line ordered by their X cooridnate. I would also like a legend automatically showing which each series is. Which high-level command can serve this purpose? I looked at my book but can't find such a command. Thanks! Mark

Hi R users, I am doing cross correlation analysis on 2 time series (call them y-series and x-series) where I need the use the model developed on the x-series to prewhiten the yseries.. Can someone point me to a function/filter in R that would allow me to do that? Thanks in advance for any help! -- View this message in context:

I have been working with the base time series object (ts) and I had a couple of questions that hopefully this group can help me with: 1) What is the best why to append an observation to an existing time-series? Suppose I have a time series: t <- ts(1:12, frequency=5) This would generate two complete cycles and one remainder. Now I would like to append an observation to this time series. I

Bueno, realmente no es necesaria que la serie esté centrada en este caso, ya que estoy sumando un ruído blanco Un saludo From: fjroar en hotmail.com To: caaperezan en gmail.com; r-help-es en r-project.org Date: Wed, 5 Nov 2014 13:00:49 +0000 Subject: Re: [R-es] Agregar ruido a una serie de tiempo Hola buenos d?as: Yo cuando he tenido que hacer estos trabajos, lo que hac?a era coger la serie

Hola:   Tengo una lista de 2 elementos, cada uno de los cuales contiene información relativa a un sujeto (Pablo y Carlos).   lSujetos <- list() lSujetos[[1]] <- list(nomfich="Pablo", colTime=5, colVars=c(6,7,8)) lSujetos[[2]] <- list(nomfich="Carlos", colTime=5, colVars=c(6,7,8)) A continuación, leo las series temporales correspondientes a cada individuo. En este caso

I am interested in a statistical comparison of multiple (5) time series' generated from modeling software (Hydrologic Simulation Program Fortran). The model output simulates daily bacteria concentration in a stream. The multiple time series' are a result of varying our representation of the stream within the model. Our main question is: Do the different methods used to represent a

Hi Users, I have daily series of data from 1962 - 2000, with the data for February 29th in leap years excluded, leaving 365 daily values for each year. I wish to convert the daily series to monthly series. How can I do this using the zoo package or any other package? Thanks ZABLONE OWITI GRADUATE STUDENT Nanjing University of Information, Science and Technology College of International

Es posible agregar ruido a una serie de tiempo Tengo series de tiempo que tienen un comportamiento funcional, quisiera agregar ruido para que parezcan señales mas reales. Normalmente las series de tiempo se suavizan a traves de filtros, es posible hacer el proceso inverso con algun paquete de R Gracias por la atención CARLOS ANDRES PEREZ [[alternative HTML version deleted]]

Hi, I have a matrix and time series "xmat". I have no problem executing any matrix functions except t(xmat) which gives the following error message. My question if "xmat" is a matrix why I can not execute this matrix function?? converting the time series and matrix into a data frame solves the problem >dim(xmat) [1] 98 7 > t(xmat) Error in "tsp<-"(*tmp*,

Hi Rusty, here is the specification for a virtio-based SCSI host (controller, HBA, you name it) so that you can apply it to the spec document and publish it. I changed the index from 7 to 8 to account for the rpmsg device, and added a feature bit to tell the guest in advance whether the host supports hotplug. Otherwise there is no change from v2.

Dear List, I was trying to verify that I could use extend.series in the wavelets package and kept getting an error when trying to use method="zero". I'm not seeing where my syntax has gone awry. According to the documentation, [see ?extend.series] " method: A character string indicating which extension method to use. Possible values are

Hello everybody, I recently wrote a "program" that to generate AR1 time series, here the code: #By Jomopo. Junio-2007, Leioa, Vizcaya #This program to create the AR1 syntetic series (one by one) #Where the mean is zero, but the variance of the serie AR1 and #the coef. of AR1 are be changed. If var serie AR1 = 1 then is standarized! #Final version for AR1 time series program #Mon Jul
