extract values from summary of function indval of the package labdsv
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)...

indicator value in labdsv
Hi,
I'm trying to find out what threshold of indicator value in labadsv should be
used to accept a specie as an indicator one? So far I assumed that indval=0.5
is high enough to avoid any mistakes but it was based only in my intuition.
I'd be greatful for any advise
best regards

INDVAL and mvpart
Hi,
I'd like to perform Dufrene-Legendre Indicator Species Analysis for
a multivariate regression tree. However I have problems with arguments
of duleg(veg,class,numitr=1000)function. How to obtain a vector of
numeric class memberships for samples, or a classification object
returned from mvpart?
thanks in advance

Indicator Species analysis; trouble with multipatt
