R6 Class for printing current sampling progress

Object is initalised with total number of iterations that are expected to occur. User can then update the object with the add method to indicate how many more iterations have just occurred. Every time step * 100 % of iterations have occurred a message is printed to the console. Use the quiet argument to prevent the object from printing anything at all

Public fields

step

real, percentage of iterations to allow before printing the progress to the console

step_current

integer, the total number of iterations completed since progress was last printed to the console

n

integer, the current number of completed iterations

n_max

integer, total number of expected iterations to be completed acts as the denominator for calculating progress percentages

quiet

logical holds whether or not to print anything

Methods

Public methods

• progressLogger$new()

• progressLogger$add()

• progressLogger$print_progress()

• progressLogger$clone()

---

Method new()

Create progressLogger object

Usage

progressLogger$new(n_max, quiet = FALSE, step = 0.1)

Arguments

n_max

integer, sets field n_max

quiet

logical, sets field quiet

step

real, sets field step

---

Method add()

Records that n more iterations have been completed this will add that number to the current step count (step_current) and will print a progress message to the log if the step limit (step) has been reached. This function will do nothing if quiet has been set to TRUE

Usage

progressLogger$add(n)

Arguments

n

the number of successfully complete iterations since add() was last called

---

Method print_progress()

method to print the current state of progress

Usage

progressLogger$print_progress()

---

Method clone()

The objects of this class are cloneable with this method.

Usage

progressLogger$clone(deep = FALSE)

Arguments

deep

Whether to make a deep clone.
