glue

Embeds R expressions within {} for direct evaluation, making code more readable and reducing syntactical noise compared to paste() or sprintf().

Interpolates from local environment, named arguments, or data frames via glue_data(), seamlessly adapting to various data sources in R workflows.

Trims empty lines and common leading whitespace while preserving indentation, ensuring clean multi-line strings without manual adjustment.

Works with vectorized data to produce strings for each row in data frames, ideal for data-driven outputs like reports or messages.

Includes glue_sql() for safe SQL query building and custom knitr engines for R Markdown, extending utility beyond basic string interpolation.
