Hi I have no knowledge of vars package. However from what you describe that it sometimes works and sometimes not (although I wonder what it does mean) it seems to me that you either mask some arguments used by the function in your environment or misspell sometimes arguments or use invalid string in response argument. It would be very unusual if irf.USAg<-irf(varest.USA, response = "g", n.ahead = 48, boot = TRUE, ci=0.95) resulted in error and when you repeat it, it does not. If you want better answer maybe from more knowledgeable people than myself, you should provide an example which works and which does not with some data (either your own or from e.g. package data). Cheers Petr

Subject: [R] vars package - irf() does not work
Dear all,
I have not received any response on this email. Is there anybody who can
help me?
I want to run an impulse response analysis using the vars() package. The code
looks as follwows.
# list of class varest
varest.USA<-VAR(VAR_analsis_DataUSA, lag.max = 24, ic = "SC", type =
"both")
varest.USA
summary(varest.USA)
#Run irf analysis
irf.USAg<-irf(varest.USA, response = "g", n.ahead = 48, boot = TRUE, ci=0.95)
plot(irf.USAg)
The problem is that R returns an error that the arguments in irf are unused.
That is, unused arguments (response="g", n.ahead = 48, boot = TRUE,
ci=0.95) The strangeness is that it sometimes works but most of the time it
does not. I installed vars() last month and irf() worked well but now it does
only occasionally. I have just edited the data but kept the code unchanged.
In addition, I have the same problem when I am trying to replicate the
example on irf() in the vars vignette althoug it also worked well when I
installed vars and run the example.
Does anybody have an idea what is wrong?

You are not giving us a fully reproducible example, nor telling us the exact error messages. However, chances are that you have another irf() function that gets in the way. Does it work with vars::irf(....) ? -pd

Two guesses are 1) you are not consistently entering the commands and thus get variable outcomes, and 2) possibly there are "depends" that irf() needs that need to updated. You could also contact the package creators. I would also observe that this looks remarkably like you might be asking for help on your homework. I would create a script of the commands you use as they work, each entered in sequence as you used it. You use it essentially as a lab notebook that documents procedures. RStudio works well for this, since you can copy each line that works from the Console to a script file in the editor. You can do the same with a text editor, while using R from a console, but it is somewhat more clumsy.

The code is written in a script and I use Rstudio. The script stops when the irf() command should be executed returning the error mentioned below. I tried to writte an independent script just for the irf() function but it does not work either with the same error.

So did you check that you have only one irf() function around?
Try findFunction("irf")

Hi
so
var.2c <- VAR(Canada, p = 2, type = "const")
irf(var.2c, impulse = "e", response = c("prod", "rw", "U"), boot = FALSE)
works only sometimes? Or it does not work with **your** data only?
If it is the later, the issue is probably in your data. You should look at them to see if
str(yourdata)
does not show some problems.

I would suggest that you comment out the offending command and re-enter it from the keyboard. It appears that the command is failing the syntax check in the command. I have not checked the vars package but it is usual to do a syntax check before the data is analysed. you could also have a look at your script in a hex editor. If this does not solve your problem I would suggest that you send to the list your script and data in text format as attachments.
