Extract Properties from Nested Column

Extracts key columns from a nested properties column in a data frame and creates new columns at the top level. The function always extracts a core set of properties and allows for flexible addition of extra columns through the ellipsis (...) parameter.

Usage

extract_properties(df, ...)

Arguments

df

A data frame or tibble containing a nested properties column.

...

<dynamic-dots> Additional column specifications to extract from the properties column. These should be provided as name-value pairs where the name is the new column name and the value is the expression to extract (e.g., user_id = properties$user_id).

Value

A data frame with the same structure as df but with additional columns extracted from the properties nested column.

Details

The function first extracts a predefined set of core columns from the nested properties column. The help_topic column is conditionally set to help_section if help_section is not NA, otherwise it retains the value from properties$topic.

Additional columns can be specified using the ... parameter, allowing for flexible extraction of other properties without modifying the function.

Examples

if (FALSE) { # \dontrun{
# Basic usage with core columns only
df_processed <- extract_properties(df_import)

# With additional columns
df_processed <- extract_properties(
  df_import,
  user_id = properties$user_id,
  timestamp = properties$timestamp,
  session_duration = properties$session_duration
)
} # }
