Forgive me if this is obvious:
I have a frame of data with the variables in each column (e.g.
Discrete_Variable1, ContinuousVariable_1, ContinuousVariable_2, ...
ContinuousVariable_n)
and I want to create a model using lrm i.e.
model <- lrm(Discrete_Variable1 ~ ContinuousVariable_1,
data=lotsofdata)
Is there a syntax for having all the continuous variables referenced
in the formula without having to enumerate them all?
I've seen the ~ . notation but when I try
model <- lrm(Discrete_Variable1 ~ ., data=lotsofdata)
I get this error:
Error in terms.formula(formula, specials = "strat") :
'.' in formula and no 'data' argument
Any help is appreciated.
