[R] INDVAL and mvpart

[astrzelczak@ps.pl]

Hello Jari,

I've tried to do the analysis this way:

> duleg(data.matrix(dane[,9:28]),predict(fit,type="vector"),numitr=1000)
Error in "row.names<-.data.frame"(`*tmp*`, value = NULL) :
        invalid 'row.names' length

I haven o idea what's going on with the row names....

cheers  :)
Agnieszka
