Figured it out.
given that object 'cit' is of class S4, extracting information works as
follows:
1)finding out names of slots in object 'cit'
> slotNames(cit)
[1] "x" "Z0" "Z1" "ZK" "type" "model"
[7] "ecdet" "lag" "P" "season" "dumvar" "cval"
[13] "teststat" "lambda" "Vorg" "V" "W" "PI"
[19] "DELTA" "GAMMA" "R0" "RK" "bp" "spec"
[25] "call" "test.name"
2) extracting info from wanted slot
> cit@teststat
[1] 5.348440 9.068113 10.643293
That's one way. There may be another: if you print the class of cit using
class(cit)
there may be a help page, which you would find using
class?foo
assuming "foo" is the name of the class. The author may have defined a
method to get what you want, or may give other guidance. For example,
in the Matrix package:
> x <- Hilbert(6)
> class(x)
[1] "dpoMatrix"
attr(,"package")
[1] "Matrix"
> class?dpoMatrix
gives quite useful information about the dpoMatrix class.
