reportTime | R Documentation |
Provides a nicely formatted "estimated time left" in loops plus a summary upon completion.
reportTime(
i,
time_start,
nIter = NULL,
reportEvery = NULL,
jobs = NULL,
prefix = ""
)
i |
current iteration |
time_start |
time when the loop started running |
nIter |
total number of iterations |
reportEvery |
report progress every n iterations |
jobs |
vector of length |
prefix |
a string to print before "Done...", eg "Chain 1: " |
