Hi, I am using the bagplot function within the aplpack package and often get this error: Error in chull(pg[, 1], pg[, 2]) : NA/NaN/Inf in foreign function call (arg 2) Here's an example of data for which this happens: bagplot(c(-4.66, -2.62, -3.65 ,-3.07 ,-4.91, -4.56 ,-3.79, -3.10, -3.01), c(2.14, -7.18, -0.15 , 2.67, -2.49, -0.89 , 0.96 , 0.59, -4.59)) Can anyone help? --

Dear r-devel members, My Rcmdr package "depends" on several other packages (tcltk, grDevices, utils, and car) and "suggests" a number of others (abind, aplpack, colorspace, effects, foreign, grid, Hmisc, lattice, leaps, lmtest, MASS, mgcv, multcomp, nlme, nnet, relimp, rgl, and RODBC). The reason for the distinction is that I don't want all of these packages to load when

hello all, i'm running R-2.6.1 on solaris 10 (x86). I added the package aplpack without problems, but when i try to use it, i got errors: > library(aplpack) Loading required package: tcltk Error in namespaceExport(ns, exports) : undefined exports :addTclPath, as.tclObj, is.tclObj, is.tkwin, tclfile.dir, tclfile.tail In addition: Warning message: S3 methods '$.tclvar',

Hello all, I'm trying to graph a scatterplot of a large (5,000 x,y coordinates) of data with the caveat that many of the data points overlap with each other (share the same x AND y coordinates). In using the usual "plot" command, > plot(education, xlab="etc", ylab="etc") it seems that the overlap of points is not shown in the graph. Namely, there are

hi: I am trying to fit prediction intervals for an arima object. My search led me to the link: http://finzi.psych.upenn.edu/R/library/forecast/html/forecast.Arima.html which has the function "forecast", as I wanted. However, when I try to run it in R, I get the message: Error in plot(forecast(fit)) : could not find function "forecast" Even the example provided on the page

hi all. i'm busy with some time series data, starting from an earlier period until the current day. i have created a time series forecast taking into account the entire data from the earlier date up until 2007, using the "forecast" package for R. i am comparing this forecasted data to the actual/ observed data (which starts from the earlier date up until the current day). my

Hi all, We followed some books and sample codes and did some EMM estimation, only to find it won't be able to generate forecast. This is because in the stochastic volatility models we are estimating, the volatilities are latent variables, and we want to forecast 1-step ahead or h-step ahead volatilities. So it is nice to have the system estimated, but we couldn't get it to forecast at

Hello, I am using forecast() in the forecast package to predict future values of an ARIMA model fit to a time series. I have read most of the documentation for the forecast package, but I can't figure out how to obtain the forecast variance for the predicted values. I tried using the argument "se.fit=TRUE," hoping this would work since forecast() calls predict(). Is there an easy

Hi, I would like to create variables in R containing parameters of summary(*Forecast Results*). Using the following code: library(forecast) data <- AirPassengers xets <- ets(data, model="ZZZ", damped=NULL) xfor <- forecast(xets,h=12, level=c(80,95)) summary(xfor) the output is: Forecast method: ETS(M,A,M) Model Information: ETS(M,A,M) Call: ets(y = data, model =

(My apologies if this is a repeated posting. I couldn't find any trace of my previous attempt in the archive.) I'm having trouble with forecast() in the dse2 package. It works fine for me on a model without a trend, but gives me NaN output for the forecast values when using a model with a trend. An example: # Set inputs and outputs for the ARMA model fit and test periods

Good day all, I'm trying to plot a continuous line plot, which is followed by two forecast points eg. one forecast point is 12 months out, and another 24 months out from the last date of the line plot. In my attempts so far, the second plot (the forecast points) is scaled against a new axis scale, thus the two plots are not directly comparable (I need the forecast points to be scaled

Dear all, I stumbled upon what appears to be a troublesome issue when sampling from an ARIMA model (from Rob Hyndman's excellent 'forecast' package) that contains a seasonal AR component. Here's how to reproduce the issue. (I'm using R 2.9.2 with forecast 2.19; see sessionInfo() below). First some data: > x <- c( 0.132475, 0.143119, 0.108104, 0.247291, 0.029510,

Dear friend, hope you are doing great, I have the following code: > myTseriesData <- ts(data[,2], start=c(2000,01), end=c(2017,9), frequency=12) > myTseriesModel <- auto.arima(myTseriesData, d=1, D=1) > myTseriesForecast <- forecast(myTseriesModel, h=12) > # I want to be able to format the dates generated by the forecast function is there a way to change the format of the

Hi everybody, I am currently trying to forecast some double seasonal time series by using the function dshw. I want to access the standard errors to build the confident interval for my forecast. I am using to following code : fit<-dshw(eem,period1=7,period2=48,h=48) then by using summary(fit), I see that my se are contained in the vector : $s20 but when I call fit$s20, I get NULL. I

I have been trying to use the ets function in the forecast package on a daily time series (ts2 is a ts object with frequency =7). However when I run the following code I get an error related to etsmodel. I have looked at ets and I can see that there is a call to the function etsmodel, but I cant seem to find info on the ets function anywhere. Does anyone know anything about the etsmodel function?

Hi I tried to calculate modified Diebold-Mariano Test in R . I have already find a "forecast" package to calculate the Diebold-Mariano Test. Please let me know how to obtain " Modified Diebold-Mariano Test" ?

Dear R Users, I am new to state-space modeling. I am using SSPIR package for Kalman Filter. I have a data set containing one dependent variable and 7 independent variables with 250 data points. I want to use Kalman Filter for forecast the future values of the dependent variable using a multiple regression framework. I have used ssm function to produce the state space (SS)
