This package is designed to assign standardized diagnoses using the Banff Classification (Category 1 to 6 diagnoses, including Acute and Chronic active T-cell mediated rejection as well as Active, Chronic active, and Chronic antibody mediated rejection).
The following steps will guide you in this process of diagnosis
assignment with the package. To get your dataset ready and in a correct
format, you must refer to the data dictionary provided with the package
here
(or using the function get_banff_dictionary() in R). This
data dictionary contains metadata specifying how your input dataset
should be formatted and what information it must contain.
A template (available
here
or get_banff_template() in R) as well as an example dataset
(available
here
or get_banff_example() in R) are also available with the
package to help you construct and prepare your dataset.
The main function banff_launcher() will go through 3
steps. It will:
Evaluate your input dataset (using
banff_dataset_evaluate() internally). If your input dataset
is not in the correct format or is missing information, a report will be
saved in your output folder and will flag variables and rows that are
not formatted properly. The next step will not run if the input dataset
is not in the correct format.
Assign diagnosis to each observation (using
calculate_adequacy() and add_diagnoses()
internally).
Save the output dataset containing diagnoses,a summary report with descriptive statistics of your output dataset, and the data dictionary.
This command example runs the diagnosis assignment process on the dataset specified in the input_file path. The output files will be saved in path_folder/example. The diagnoses will be displayed in English and only observation with adequacy == 1 will be taken into consideration due to the option_filter argument. Finally, the output dataset will contain variables generated in the process due to the argument “detail” set to TRUE.
