# Importing Marginal Distributions

Marginal distributions provided by a TRE should contain the following files:

- binary_variables.csv
- categorical_variables.csv
- continuous_variables.csv
- continuous_quantiles.csv
- summary.csv

Depending on the data from the TRE some of the files may not be present.

The marginal distributions can be imported using the `import_marginal_distributions()` function. By default the marginal distributions will be imported from the current working directory:

    library(RESIDE)
    marginals <- import_marginal_distributions()

The folder of the marginals can be changes using the `folder_path` parameter of the `import_marginal_distributions()` function:

    library(RESIDE)
    marginals <- import_marginal_distributions(
      folder_path = "/Users/ryan/marginals"
    )

Additionally any of the file names can be changed using the relevant `import_marginal_distributions()`

parameters:

- `binary_variables_file`
- `categorical_variables_file`
- `continuous_variables_file`
- `continuous_quantiles_file`
- `summary_file`

However this is generally not advised.
