print_loop_progress

R Documentation

print loop progress

Description

Print current progress inside a loop (e.g., for loop or lapply)

Usage

print_loop_progress(
  iteration_number = NULL,
  iteration_start = 1,
  iteration_end = NULL,
  text_before = "",
  percent = 1,
  output_method = "cat"
)

Arguments

`iteration_number`	current number of iteration
`iteration_start`	iteration number at which the loop begins (default = 1)
`iteration_end`	iteration number at which the loop ends.
`text_before`	text to add before "Loop Progress..." By default, it is set to be blank, i.e., `text_before = ""`
`percent`	if `percent = 1`, progress level will be printed at every 1 percent progress (default = 1)
`output_method`	if `output_method = "cat"`, progress level will be printed using the 'cat' function; if `output_method = "return"`, progress level will be returned as the output of the function (default = "cat")

Examples

for (i in seq_len(250)) {
  Sys.sleep(0.001)
  print_loop_progress(
    iteration_number = i,
    iteration_end = 250)
}
unlist(lapply(seq_len(7), function (i) {
  Sys.sleep(0.1)
  print_loop_progress(
    iteration_number = i,
    iteration_end = 7)
  return(i)
}))
