[R] Help in R code
Good morning, Please help me to code this code in R. I working in the multivariate time series data, know my objective is that to one year forecast of the hourly time series data, using first five as a training set and the remaining one year as validation. For this I transform the the data into functional data through Fourier basis functional, apply functional principle components as dimensional reduction explaining a specific amount of variation , using the corresponding functional principle components scores. I use the VAR model on those FPCscores for forecasting one day ahead forecast, know my problem is that i choose four Fpc scores which give only four value in a single day, I want the forecast for 24 hours not only 4, and then i want to transform it back to the original functional data. for the understanding i am sharing my code (1) transform of the multivariate time series data in functional data(2) the functional principle components and the corresponding scores(3) I use functional final prediction error for the selection of the parameters on the VAR model(4) Using VAR for the analysis and forecasting .(1) nb = 23 # number of basis functions for the data fbf = create.fourier.basis(rangeval=c(0,1), nbasis=nb) # basis for data args=seq(0,1,length=24) fdata1=Data2fd(args,y=t(mat),fbf) # functions generated from discretized y(2) ffpe = fFPE(fdata1, Pmax=10) d.hat = ffpe[1] #order of the model p.hat = ffpe[2] #lag of the model (3) n = ncol(fdata1$coef) D = nrow(fdata1$coef) #center the data mu = mean.fd(fdata1) data = center.fd(fdata1) #fPCA fpca = pca.fd(data,nharm=D) scores = fpca$scores[,1:d.hat](4) # to avoid warnings from vars predict function below colnames(scores) <- as.character(seq(1:d.hat)) VAR.pre= predict(VAR(scores, p.hat), n.ahead=1, type="const")$fcst after this I need help first how to transform this into original Functional data and to obtain the for for each 24 hours (mean one day forecast) and to how to generalize the result for one year.

Re: [R] help for R code
Hi Ablaye, The CRAN repository has thousands of available R packages. To help people find relevant packages amid such a huge collection, there are some 'task view' pages that group packages according to a particular task. I am guessing that you are interested in kernels because of their use in machine learning, so you might want to look at the Machine Learning task view at: https://cran.r-project.org/web/views/MachineLearning.html If you search for 'kernels' on that page you will find 'Support Vector Machines and Kernel Methods' which mentions a few packages that use kernels.

Hi Faheem,
This is a complete guess, but the hours of the day may range from 0 to
23 not 1 to 24. So you may be asking for an out of range hour.

Re: [R] Help in R code
Read the Posting Guide. Assuming your question is not about homework or statistics, the answer is probably yes. After reading the the Posting Guide you will also know that this is a plain text email list so you will need to set your email program appropriately. You will also know that a minimal example including data is (almost always) needed, but you might want to read some help about what that actually looks like [1][2][3], since many attachment types are also not allowed on the list. If this seems like a lot of work, keep in mind that we can't read your mind and you will eventually have to break your problem down this way anyway, and you might just figure out the answer yourself if you are thorough in writing your minimal example.

Re: [R] Help in R code
Hi
Keep your reply to the list.
Hm. There is natural language processing section in Task View. Maybe you could
use already developed instruments for processing text. I vaguely remember there
was also some article in R journal about text mining.
And searching internet by
R text mining
gave me plenty of possible suggestions including e.g package tm.
First line of your code gave me an error
> s <- unlist(lapply(posText, function(x) { str_split(x, "\n") }))
Error in lapply(posText, function(x) { : object 'posText' not found
And again
you still fail to keep to the recommended way of asking questions
1. Plain text, not HTML posts
2. input and output data sent as result of dput(posText[selection])
3. provide ***reproducible*** code
Instead of trying to persuade all of us to accept your way of mailing you shall
comply to ours if you want any reasonable help.

OK. Some very quick help: 1. Do not post in HTML, your mail is barely readable. 2. Send some data by using output from dput(yourobject) 3. Instead of vaguely explaining what you want to do, prepare desired output and again show it by dput(yourresult) 4.
