timeR: A R6 Class to represent a timer.

Description

timer is a R6 Class that represent a timer. This is a modified version of the timeR package for an internal use. Full credit is to Yifu Yan, the author of the timeR package.

Value

getTimer returns a data frame with all records saved by the timer object. Columns in the data.frame are: event, start, end, duration, RMSE, MAE, stars, params, comment.

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/Print a data.frame with all records.

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.

getDuration()

Get duration for a selected event.

getRMSE()

Get the RMSE for a selected event.

getMAE()

Get the MAE for a selected event.

getStars()

Get stars for a selected event.

getParams()

Get params 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.

Public 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.

Active bindings

time

A POSIXct/POSIXlt value of your latest timing.

event

A string of your latest timing.

Examples

# NOT RUN {
timer <- createTimer()
timer$start("event1")
## put some codes in between, for instance
Sys.sleep(1)
timer$stop("event1", RMSE = 1, MAE = 1.3, stars = "*", 
           params = "maxiter=100, lr=0.01", comment = "OK for 1",  
           printmsg = TRUE)

timer$start("event2")
## put some codes in between, for instance
Sys.sleep(2)
timer$stop("event2", RMSE = 2, MAE = 2.6, stars = "**",  
           params = "maxiter=1000, lr=0.001", comment = "OK for 2",  
           printmsg = FALSE)

table1 <- getTimer(timer)
timer$toggleVerbose() # set verbose to FALSE as default is TRUE
table1 # print all records in a data frame

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