Hello R help list,
I am using the mda package and in particular the fda routine to classify in
terms of gear a set of 20 trips.
I preformed a flexible discriminant analysis (FDA) using a set of 151
trips.
FDAT1 <- fda(as.factor(gear) ~ . , data =matrizR)
A total of 22 predictors were considered. 20 of the predictors are
"numeric" and 2 are "factors".
The resulting FDA rule was applied to the 20 trips and for the same
predictors in order to predict the type of gear used. however a consistent
error is occuring:
Error in polybasis(newdata, degree, monomial) %*% object$coef :
non-conformable arguments
it is possible the problem being related with the 2 predictors that are
entering as factors?
if someone can help, would be very grateful.
cheers,
Catarina
