[R] Displaying Iteration Count

[Shotwell, Matthew S]

or... for every 100 iterations

telliter <- 100
for( iter in 1:maxiter ) {
    #do some cool statistics
    if( iter %% telliter == 0 ) cat(paste("iteration", iter, "complete\n"))
}

Try this:

for(i in 1:10) {
    print(sprintf("Interation: %d", i))
    flush.console()
    Sys.sleep(1)
}
