The merge.occasion.data function in the current version of RMark will not assign unique occasion- and group-specific covariate values - only values unique to each occasion (time). In the next version of RMark, the merge.occasion.data function will include the argument "bygroup" (T or F, default = F). By setting "bygroup" to TRUE, the function will assign occasion- and group-specific values from the data frame "df" to the design data. Thanks JL!
