hmstimer

hmstimer is an R package to track elapsed clock time using a hms::hms scalar.

hmstimer was originally developed to time Bayesian model runs. It should not be used to estimate how long extremely fast code takes to execute as the package code adds a small time cost.

Create and start a timer with tmr_timer(start = TRUE).

library(hmstimer)

tmr <- tmr_timer(start = TRUE)
Sys.sleep(0.1)
str(tmr)
#>  'hms' num 00:00:00
#>  - attr(*, "units")= chr "secs"
#>  - attr(*, "title")= chr ""
#>  - attr(*, "start")= num 1.72e+09
hms::as_hms(tmr)
#> 00:00:00

Get the elapsed time with tmr_elapsed(). The title is optional.

tmr <- tmr_timer(start = TRUE, title = "my timer")

Sys.sleep(0.1)
tmr_elapsed(tmr)
#> 00:00:00.103417

Sys.sleep(0.1)
tmr_elapsed(tmr)
#> 00:00:00.212112

Stop the timer with tmr_stop().

tmr <- tmr_stop(tmr)
tmr_elapsed(tmr)
#> 00:00:00.216109

Sys.sleep(1)
tmr_elapsed(tmr)
#> 00:00:00.216109

Restart the timer with tmr_start().

tmr <- tmr_start(tmr)
tmr_elapsed(tmr)
#> 00:00:00.21697
Sys.sleep(0.1)
tmr_elapsed(tmr)
#> 00:00:00.324928

There are several options for printing and formatting including coercing to a hms object.

tmr <- tmr_stop(tmr)
print(tmr)
#> 00:00:00.333247
tmr_print(tmr)
#> [1] "00:00:00.333247 [my timer]"
tmr_format(tmr, digits = 5)
#> [1] "00:00:00.33325 [my timer]"

If running tmr_print() behaves differently.

tmr <- tmr_start(tmr)
tmr_print(tmr)
#> [1] "14:44:58 (+00:00:01 => 14:44:59) [my timer]"

The time for a block of code to complete can be printed using with_timer().

with_timer({
  Sys.sleep(0.1)
  Sys.sleep(0.1)
  1 + 1
})
#> 00:00:00.207
#> [1] 2
