My question concerns the baseline state for continuous variable in

I have a model which can be reduced to:

The model makes perfect sense if the baseline
I should rephrase my question.
When using the notation rcs(V1, N) within the lrm function in the rms
package, the associated model reports out N-1 values for the associated
variable. Fine.
The rcs-constructed temporary variables are denoted V1, V1', V1'' when
one looks at the model output,
