timeR: A package to make timing codes easier

Description

The timeR package saves your time by timing your code and save recordings to a data frame automatically.So you don't have to do all these steps manually by yourself.

timer is a R6 Class that represent a timer.

Usage

timeR

Format

An object of class R6ClassGenerator of length 24.

Fields

time: A POSIXct/POSIXlt value of your latest timing.
event: A string of your latest timing.
eventTable: A data frame that stores all timings.
verbose: A printing setting that controls whether to print messages.

Public Methods

initialize(time,event,verbose,eventTable): Initialize a timer object. You can also use createTimer() function to initialize a timer object.
start(eventName): Start timing for a event, eventName should be a string
stop(eventName): Stop timing for a event.
getTimer(): Get a data frame that stores all recordings.You can also use getTimer() function to get the data frame.
removeEvent(eventName): Remove an given row in the eventTable.
toggleVerbose(): Toggle between TRUE and FALSE for verbose
getStartTime(): Get start time for a selected event.
getStopTime(): Get stop time for a selected event.
getTimeElapsed(): Get time elapsed for a selected event.
getComment(): Get comment for a selected event.
getEventf(): Get entire row for a selected event.
print(): Custom print method for timer class. However, you don't need to use this function to generate custom printing. Custom printing is triggered by default.

Private Methods

slprint(msg,flag = self$verbose): A function that controls whether to print extra message.

Examples

timer <- createTimer(precision = "ms")
timer$start("event1")
# put some codes in between
timer$stop("event1")

timer$start("event2")
# put some codes in between
timer$stop("event2",comment = "event 2 completed")

table1 <- getTimer(timer)
timer$toggleVerbose() # set verbose to FALSE as default is TRUE

table1 # print all records in a tibble(data frame)

# get attributes for selected events
timer$getStartTime("event1")
timer$getStopTime("event1")
timer$getTimeElapsed("event1")
timer$getComment("event1")
timer$getEvent("event1")

Create a timer object

Description

Create a timer object

Usage

createTimer(verbose = T, precision = "s")

Arguments

verbose

A parameter to control whether to print messages while using methods. Default to TRUE.

precision

Precision for time, default to s, valid values are: s,ms and us

Value

a timer object.

Examples

timer1 <- createTimer() # print is enabled
timer1 <- createTimer(FALSE) # print is disabled
timer1$start("event1") # start timing for event 1
timer1$stop("event1", comment = "event 1 stopped") # stop timing for event 1(comment is optional)
getTimer(timer1) # get all records in a data frame

Get the data frame in timer object

Description

timer object has a built-in data frame that contains all timings. run this function to extract the data frame.

Usage

getTimer(object)

Arguments

object

The name for timer object.

Value

A data frame containing all records of a timer object.

Examples

timer1 <- createTimer()
timer1$start("event1")
Sys.sleep(1)
timer1$stop("event1")
getTimer(timer1)
