Produce counts of Number of subjects, number of events, number of subjects with events, and proportion of subjects with events

A short cut - instead of calling the individual function (n_sub, n_event, n_subj_event, p_subj_event), one call to this function will produce all the described functions. This can be useful to save compute time as inside the chef pipeline there will be fewer iterations.

Usage

count_set(dat, event_index, cell_index, subjectid_var, ...)

Arguments

dat

data.table. The analysis data set.

event_index

vector of integers that index the rows in dat that match the definition of an 'event'. Matching is done via the INDEX_ column in dat.

cell_index

A vector of integers referencing the rows of dat (as specified by the INDEX_ column in dat) that match the population to be analyzed. See the "Endpoint Events" vignette in ramnog for more information.

subjectid_var

character. Name of the subject identifier variable in the data (default is "USUBJID").

...

Optional parameters.

Value

a data.table containing all statistical outputs
