[R] rms R code

[Bond, Stephen]

Greetings, useRs.

Does anybody have replication of the examples from the RMS book by Harrell coded in R? I find that most the code does not work and it takes too much time to debug.

For example from p.276
> age.t <- w[,"age"]
> f.full <- lrm(cvd~scored(rx)+rcs(dtime,5)+age.t+wt.t+pf.t+hx+sbp+ekg.t+sz.t+sg.t+ap.t+bm+hg.t,x=T,y=T)
Error in model.frame.default(formula = cvd ~ scored(rx) + rcs(dtime, 5) +  : 
  invalid type (list) for variable 'age.t'

thanks everybody.

Stephen
