Re: [R] (no subject)

[Jim Lemon]

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

Re: [R] Lag function

[Bert Gunter]

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 moves it forward 24 hours. This means that the day 2 observations
are those from day 1, etc., which is usually what is wanted for lag. But
you decide.

Cheers,
Bert

[R] Lag function

[Edoardo Silvestri]

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

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

[Rui Barradas]

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.)

[R] installing R in Amazon linux AMI

[akshay kulkarni]

dear members,
I am using R in AWS. I am currently using RHEL AMI 
in ec2 instance. I want to shift to Amazon LINUX AMI to lower costs.

How do you install R in Amazon lINUX AMI? I have searched the web, and , to my 
disappointment have not found any articles on how to install R in Amazon linux 
AMI, as is there for RED HAT AMI.

Any help?

Very many thanks for your time and effort...
yours sincerely,
AKSHAY M KULKARNI

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.

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
