Check differences in xp_trt_code

Check differences between xp_trt_code values between a reference dataframe (typically moda_desc) and an other dataframe (typically an observation dataset). Most of the time xp_trt_code are not saved in raw observation datasets : observation dataset should then be merged before with plot_desc, using merge_data_plotdesc()

Utilisation

check_xptrtcode_diff(df_as_ref, df_to_test)

Arguments

df_as_ref

a reference dataframe with a xp_trt_code col

df_to_test

a dataframe to test with a xp_trt_code col

Valeur de retour

TRUE if differences are detected (NA are ignored)
