Details
In addition to the fields that are input from outside, the required fields are acquired by tools:::.get_standard_repository_db_fields() and "File".
All of these fields are combined as a character vector.
If filters is NULL, then available.packages tries to get the value by calling getOption("available_packages_filters").
Value
returns a matrix with each row identifying a package. Each row name is the package name, and the column names are defined by fields
and the standard repository fields.
