Re: [R] (no subject)

Hi malika, You don't seem to have defined your functions correctly. For example: H<-function(u,x1) would define an empty function H if that command worked, but it doesn't Jim On Tue, Aug 7, 2018 at 3:51 PM, malika yassa via R-help wrote: > hellothis is my programmeyou can help me, i cann't fo

Re: [R] Lag function

Well, maybe. Whether it's +24 or -24 depends on what you mean by "one day lag." I suspect you mean -24, but perhaps this will help you decide: test <- ts(1:72, frequency = 24) plot(lag(test,24)) plot(lag(test,-24)) Note that the +24 moves the time base back 24 observable units (= hours) and -24 m

[R] Lag function

I have an hourly database and I defined a variable as follows: time<-ts(data$variable, frequency=24) If i need to create the variables with one day lag, the corresponding command is lag(time,24)? Thank you [[alternative HTML version deleted]]

Re: [R] loop over matrix: subscript out of bounds

Hello, If it is not running as you want it, you should say what went wrong. Post the code that you have tried and the expected output, please. (In fact, the lack of expected output was the reason why my suggestion was completely off target.) Rui Barradas On 07/08/2018 09:20, Maija Sirkjärvi w

Hi Kenneth, My guess is that you have tried to send screenshots of your output and these were blocked. Try to cut and paste the output into your message. Jim On Tue, Aug 7, 2018 at 6:38 PM, John wrote: > On Mon, 6 Aug 2018 20:18:38 +0200 > kenneth Barnhoorn wrote: > > Your examples did not app

Thanks, but I didn't quite get it. And I don't get it running as it should. ti 7. elok. 2018 klo 10.47 Martin Maechler (maech...@stat.math.ethz.ch) kirjoitti: > > > Thanks for help! > > However, changing the index from i to j for the column vector changes the > > output. I would like the matrix t

Re: [R] loop over matrix: subscript out of bounds

Thanks for help! However, changing the index from i to j for the column vector changes the output. I would like the matrix to be the following: -1 1 0 0 0 0 0 0 -1 1 0 0 0 0 0 0 -1 1 0 0 0 . etc. How to code it? Best, Maija >> myMatrix <- matrix(0,5,12) >> for(i in 1:nrow(myMatrix)) { >>
