profvis

Visualize R profiling data

JavaScript

profvis is a tool for visualizing code profiling data from R. It creates an interactive web-based interface for exploring performance data collected during code execution.

The package wraps R expressions with profvis() to collect profiling data and automatically generates an interactive visualization in a web browser. It returns an htmlwidget object that can be saved and viewed later, making it easy to analyze where code spends time and identify performance bottlenecks. The graphical interface provides a more intuitive way to explore profiling data compared to raw text-based output.
