The simple answer to my problem (are the values of a vector
numeric or not) is is.numeric, and that is enough for
what I need right now.
But this way I do not get an answer discriminating between
integers and and doubles. What is the canonical way of getting the
type of the values of a vector?
Is there a better way than
valtype<-function(x)
typeof(ifelse(is.factor(x),levels(x),x))
