recommended dose. To conduct a trial using at most 20 patients, where dose is
re-evaluated after every second patient, use <code><a href='https://rdrr.io/r/base/rep.html'>rep(2, 10)</a></code>. To conduct a
trial of 8 patients where dose is re-evaluated after each single patient, use
<code><a href='https://rdrr.io/r/base/rep.html'>rep(1, 8)</a></code>. Cohort size need not be uniform. E.g.
<code><a href='https://rdrr.io/r/base/c.html'>c(rep(1, 5), rep(3, 10))</a></c
