The name of a figure's data in its program — tfl_fig_data

A designed figure's data steps make one data frame that its layers draw from. In the program it is named for what it is, as the ARD programs name theirs: <dataset>_<parameter> (adtte_ttde), else <dataset>_<population> (adsl_saf). Code of the design's own (a code step, a layer_code layer) says df and is written with the name too. A design with neither a parameter nor a population keeps df, and so does one whose code has the name already.

Usage

tfl_fig_data_name(design)

Arguments

design: A tfl_fig_design().

Value

The name, or NULL when the program calls it df.

Examples

tfl_fig_data_name(tfl_fig_template("km_simple", data = "ADTTE", param = "TTDE",
                                   pop = "SAFFL", group = "TRT01A"))
#> [1] "adtte_ttde"
