Hi I'm getting an error message with the roots() function in the vars package. Even the example in the help file comes up with an error:
data(Canada) var.2c <- VAR(Canada, p = 2, type = "const") roots(var.2c)
Error in UseMethod("roots") :
no applicable method for 'roots' applied to an object of class "varest"
The error is odd, for the help file explains that one of the arguments of the roots() function is an object of class "varest" generated by VAR() -exactly the class of object that var.2c is:
class(var.2c)
[1] "varest" May it be that I'm using the latest version of R -in Windows- (ie 2.15.3 ), perhaps? Jose Wrap Up and Run 10k is back!

You really need to provide the information requested in Posting Guide. The example works just fine for me.
