Memory allocation by source line

Source: R/memory.R
pv_memory_lines.Rd

Returns memory allocation aggregated by source location. Requires source references (use devtools::load_all() for best results).

Usage

pv_memory_lines(x, n = NULL)

Arguments

x

A profvis object.

n

Maximum number of lines to return. If NULL, returns all.

Value

A data frame with columns:

  • location: File path and line number

  • label: Function name at this location

  • filename: Source file path

  • linenum: Line number

  • mem_mb: Memory allocated in megabytes

Examples

p <- pv_example()
pv_memory_lines(p)
#>            location    mem_mb                            label       filename
#> 1 example_code.R:13 2.6303101                            rnorm example_code.R

#> 3 example_code.R:21 0.3564835 result[i] <- sqrt(abs(x[i])) * 2 example_code.R
