R help - Apr 2012 - object of type 'S4' is not subsettable

hey there!

The object 'cit' contains:
> cit
##################################################### 
# Johansen-Procedure Unit Root / Cointegration Test # 
##################################################### 

The value of the test statistic is: 5.3484 9.0681 10.6433
---------------
I want R to save the value 5.3484 in a new object. I am used to use the
command x=cit[a] where a stands for the place where R has saved the value.
However, the johansen procedure works with S4 objects with which subsetting
does not seem to work.

Any ideas how I could get R save a certain value of the output into a new
object?

Thousand thanks,
Philipp

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 at teststat
[1]  5.348440  9.068113 10.643293
