Load and format data object
Usage
load_data(
time,
cluster_id,
individual_id = NULL,
treatment,
outcome,
time_type = "discrete",
data
)Arguments
- time
A character string; the name of the numeric variable representing time. Time can be either discrete or continuous.
- cluster_id
A character string; the name of the numeric variable identifying the cluster.
- individual_id
A character string (optional); the name of the numeric variable identifying the individual.
- treatment
A character string; the name of the binary variable indicating treatment. Values must be either integers (0/1) or Boolean (T/F).
- outcome
Either a character string or a vector of two character strings; for a numeric or binary outcome, the single character string indicates the name of the numeric or binary outcome variable; for binomial outcome data, the vector of two character strings indicates the "# of successes" variable and the "# of trials" variable, respectively. Values in the outcome variable(s) must be either numeric or Boolean (T/F).
- time_type
One of c("discrete", "continuous"); whether the model treats time as discrete or continuous.
- data
A dataframe containing the stepped wedge trial data.
Examples
example_data <- load_data(time ="period", cluster_id = "cluster", individual_id = NULL,
treatment = "trt", outcome = "outcome_cont", data = sw_data_example)
base::summary(example_data)
