TRTR.RTRT.TRRT.RTTR | R Documentation |
Dataset from the public domain to be evaluated by method.A()
and/or method.B()
.
Reference Dataset 23
22 subjects.
Unbalanced (four subjects in sequence RTRT and six in each of the other three) and complete. Two outliers (subjects 8 and 17) in sequence TRTR.
A data frame with 88 observations on the following 5 variables:
subject | a factor with 22 levels: 1, 2, ..., 27 |
period | a factor with 4 levels: 1, 2, 3, 4 |
sequence | a factor with 4 levels: TRTR, RTRT, TRRT, RTTR |
treatment | a factor with 2 levels: T, R |
PK | a numeric vector of pharmacokinetic responses acceptable for reference-scaling (here Cmax) |
Dataset | N | CVwR (%) | Evaluation |
rds23 | 22 | >30 | method.A() , method.B()

In software sequences and treatments are ranked in lexical order. Hence, executing str()
or summary()
will show sequence
as "RTRT", "RTTR", "TRRT", "TRTR"
and treatment
as "R", "T"
. In BE – by convention – sequences are ordered with T
first. The package follows this convention.
