[R] extract values from summary of function indval of the package labdsv

[katse]

Hi everybody,
I am doing Indicator species analysis using the function "indval" from the
package "labdsv". 
For further analysis I need the values "Number of Significant Indicators"
and "Sum of Indicator Values" that is calculated from the summary on my
indval object. 

 indication3<-indval(Veg,caver3,numitr=4999)

 summary(indication3)
 cluster indicator_value probability
X14        1          0.9423  0.00020004
X10        1          0.8993  0.00040008
...

Sum of probabilities                 =  22.7643528705741 

Sum of Indicator Values              =  57.55                                                                                                                                        

Sum of Significant Indicator Values  =  17.03 

Number of Significant Indicators     =  22 

Significant Indicator Distribution

 1  2  3 
10 10  2 

I tried to extract them using "summary(indication3)$Sum of Indicator Values"
for example, but it doesn't work. Is there a way to get the values?
Someone has an idea?
Thanks
katse
