This function checks the number of trials in the input
dataframe and determines the index of the currently passed
checkpoint and the next checkpoint based on the stopping points
determined in the sequential analysis plan. If raw data are provided
the function drops all the non-erotic trials (see clean_data).
The function uses the following checking points: (`r analysis_params$when_to_check`).
tell_checkpoint(df)dataframe, the input dataframe
The function returns a list of three. The number of trials, the index of the currently passed checkpoint, the index of the next checkpoint.
