Total time summary by function

Source: R/time.R
pv_total_time.Rd

Returns the time spent in each function including all its callees. This shows which functions are on the call stack when time is being spent.

Usage

pv_total_time(x, n = NULL, min_pct = 0, min_time_ms = 0)

Arguments

x

A profvis object.

n

Maximum number of functions to return. If NULL, returns all that pass the filters.

min_pct

Minimum percentage of total time to include (default 0).

min_time_ms

Minimum time in milliseconds to include (default 0).

Value

A data frame with columns:

  • label: Function name

  • samples: Number of profiling samples where function appeared

  • time_ms: Time in milliseconds

  • pct: Percentage of total time

Examples

p <- pv_example()
pv_total_time(p)
#>                              label samples time_ms   pct
#> 1                     process_data      14      70 100.0
#> 2                    generate_data      13      65  92.9
#> 3                            rnorm       6      30  42.9
#> 4                 x[i] <- rnorm(1)       4      20  28.6
#> 5 result[i] <- sqrt(abs(x[i])) * 2       1       5   7.1
#> 6                   transform_data       1       5   7.1

# Only functions with >= 50% total time
pv_total_time(p, min_pct = 50)
#>           label samples time_ms   pct
#> 1  process_data      14      70 100.0
