pbarETA

This is an extended version of the txtProgressBar function from the utils package. Please refer to that documentation with help(txtProgressBar, utils). Use library(pbarETA, warn=F) to override utils::setTxtProgressBar with pbarETA::setTxtProgressBar.

|===========                                                           |  10%, ETA 01:24

Some notes:

• Adding library(pbarETA, warn=F) to an existing script will provide ETA to any txtProgressBar object.
• The estimation is accurate when different iterations tend to take the same amount of time.
• Shows the significant part of Years:Months:Days:Hours:Minutes:Seconds.
• Redrawn at least once per second (the original txtProgressBar is redrawn when values change).
• Only tested for bar style=3 (default for pbarETA).
