r2lFindClass sets the basic type of a vector.
r2lFindClass(variable, limDiscrete = 10)
variable |
vector whose type is to be set. |
limDiscrete |
numberic; fixes the limit that distinguishes continuous variables
from discrete ones. See details below. |
r2lFindClass determines the basic type of a vector, as
defined in r2lUniv. The rules are the following:
factor becomes nominal.
logical becomes nominal.
ordered becomes ordinal.
integer or numeric become either discrete
or continuous:
discrete
continuous
numeric. We do not here consider the class, but the nature
of the variable.
limDiscrete. If a vector has more than
limDiscrete different observations, it will be
continuous. Otherwise, it is elligible for being
discrete (if the second condition holds).
A vector of characters containing in first position the
r2l basic class, then the R class of the object (the R class is
not erased by r2lFindClass, it just becomes secondary class)
