This will take a dataframe with each row being the outcomes, etc., for a given group for a given month and aggregate those groups for each month.

dat,
outcomename,
groupname,
Nname,
is_count = FALSE,
rich = TRUE,
covariates = NULL
)
|
dat |
Dataframe with one row for each time point and group that we are going to post stratify on. This dataframe should also have an column with passed name "Nname" indicating the number of cases that make up each given row. It should have a 'month' column for the time. |
outcomename |
String name of the outcome variable in dat. |
groupname |
Name of the column that has the grouping categorical variable |
Nname |
Name of variable holding the counts (weight) in each group. |
is_count |
If TRUE the data are counts, and should be aggregated by sum rather than by mean. |
rich |
If TRUE, add a bunch of extra columns with proportions of the month that are each group and so forth. |
covariates |
group-invariant covariates to preserve in the augmented rich dataframe. These are not used in this method for any calculations. Pass as list of column names of dat |
Dataframe of aggregated data, one row per month. If rich=TRUE many extra columns with further information.
