Re: [R] Time-series moving average question

For your first question, you’re doing moving averages of 3 points (I assume that’s what order=3 does). For any given time point of your input data, that would be one before, one at, and one after the given time point. Do all of your input times have both one before and one after? Don’t know ab

I see this problem in 2.6-7 (version on CRAN) but it's now fixed in dev on RForge, you can try it out by installing from there, or from the Github mirror with devtools::install_github("rforge/raster/pkg/raster"). There's an imminent release to CRAN some time soon. Cheers, Mike. On Sat, 2 Jun 20

Re: [R] Regroup and create new dataframe

Hello, I don't understand why you are splitting data1 and then unlisting the result. if you want to apply a modeling function to each of the subdf's, split by Product name, you can follow more or less these steps: 0. Create a dataset set.seed(9376)    # Make the results reproducible n <-

Your question raises several issues. First, we do not do homework here, so if this is an assignment, you will not get much help. Second, you need to send your emails as plain text, not html. Third, you need to provide a reproducible example and send your data using dput() so that we can follow w

[R] rasterize SpatialPolygon object using a RasterBrick object

One way is values <- lapply(lis, get) You can do names(values) <- lis to attach the object names to the values in the list returned by lapply. Bill Dunlap TIBCO Software wdunlap tibco.com On Fri, Jun 1, 2018 at 7:25 AM, Christian wrote: > Hi, > > I have searched the documentations of eva

Hi Don, wow, you are so right. I picked that piece up from the bloggers tutorial and since I am R naive yet, I thought it was all one step moving_average = forecast(ma(tdat[1:31], order=2), h=5) Truly, I usually print and check at every step I can, as painful as it is sometimes. Great lesson fo

Re: [R] Time-series moving average question

You are right that there are no NAs in the practice data. But there are NAs in the moving average data. To see this, break your work into two separate steps, like this: tnr.ma <- ma(dat3[1:28], order=3) TNR_moving_average <- forecast(tnr.ma, h=8) I think you will find that the warning comes

Re: [R] Time-series moving average question

My guess would be that if you inspect the output from ma(dat3[1:28], order=3) you will find some NAs in it. And then forecast() doesn't like NAs. But I can't check, because I can't find the ma() and forecast() functions. I assume they come from some package you installed; it would be helpful
