Construct Treatment Matrix
Description
Constructs a matrix of '#cluster' rows and '#timepoint' columns, indicating treatment status in each cluster at each timepoint.
Usage
construct_trtMat(Cl, trtDelay, dsntype, timepoints = NULL)
Arguments
Cl |
integer (vector), number of clusters per sequence group (in SWD), or number in control and intervention (in parallel designs) |
trtDelay |
numeric (possibly vector), 'NA'(s) and/or value(s) between '0' and '1'. 'NA' means that first (second, ... ) period after intervention start is not observed. A value between '0' and '1' specifies the assumed proportion of intervention effect in the first (second ... ) intervention period. |
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. |
Value
a matrix trtMat, where rows and columns correspond to cluster and timepoints, respectively
Examples
construct_trtMat(Cl=c(1,2,1), trtDelay=c(.2,.8), dsntype="SWD")
