Dear all,

I re-checked the codes and found
as.numeric(substr("parallel", 1, 1))
[1] NA   ### from 'as.numeric("p")'
sequences("parallel")
[1] "A" "B"
Warning message:
In sequences("parallel") : NAs introduced by coercion


Q1: So this is where that warning message comes from.
Q2: Nope, cannot do it with sequences("parallel",tmts=c("R","T")).
Q3: Ok, it still works and it just happens to design=="parallel".
Q4: not implemented yet for sure.

All the best,
