construct_incompMat R Documentation
Constructs a matrix of 'NA' and '1' for unobserved and observed cluster periods, respectively.
Description
Mostly useful to build incomplete stepped wedge designs
Usage
construct_incompMat(incomplete, dsntype, timepoints, Cl, trtmatrix = NULL)
Arguments
incomplete
integer, either a scalar (only for SWD) or a matrix.
A vector defines the number of periods before and after the switch from
control to intervention that are observed. A matrix consists of '1's for
observed clusterperiods and '0's or 'NA' for unobserved clusterperiods.
dsntype
character, defines the type of design. Options are "SWD",
"parallel" and "parallel_baseline", defaults to "SWD".
timepoints
numeric (scalar or vector), number of timepoints (periods).
If design is swd, timepoints defaults to length(Cl)+1.
Defaults to 1 for parallel designs.
Cl
integer (vector), number of clusters per sequence group (in SWD),
or number in control and intervention (in parallel designs)
trtmatrix
an optional user defined matrix
to define treatment allocation
Value
a matrix
