Text-based flame graph

Generates an ASCII representation of a flame graph showing the hierarchical breakdown of time spent in the call tree.

Usage

pv_flame(x, width = 70, min_pct = 2, max_depth = 15)

Arguments

x

A profvis object.

width

Width of the flame graph in characters.

min_pct

Minimum percentage to show (filters small slices).

max_depth

Maximum depth to display.

Value

Invisibly returns the flame data structure.

Examples

p <- pv_example()
pv_flame(p)
