Hello,
using the Design library, and the following command (from the Harrell's book,
example at Ch.20):
dd <- datadist(rx, age, wt, pf, pf.coded, heart, map, hg, sz, sg, ap, bm)
options(datadist=='dd')
I get the following error:
Error in datadist == "dd" : comparison (1) possible only for atomic data or list
What does it means?
thank you,
giulia
