memtools

Overview

memtools provides debugging tools to detect and solve memory leaks in R:

• Record memory snapshots of the R heap.
• Compare snapshots to detect leaked objects with a large retained size.
• Inspect the shortest paths between nodes (e.g. between a leaked node and its dominator).

See vignette("memtools") for a tutorial.
