Dear all,
I am processing a very long and complicated list using lapply through a custom
function and I would like to generate some sort of progress report. For
instance, print a dot on the screen every time 1000 item have been process. Or
even better, reporting the percent of the list that have been process every
10%. However, I can't seem to figure out a way to achieve that.
For instance, I have a list of 50,000 slots:
aList <- replicate(50000,list(rnorm(50)))
That need to be process through the following custom function:
myFnc <- function(x){
tTest <- t.test(x)
return(list(p.value=tTest$p.value,t.stat=tTest$stat))
}
Using an lapply statement, as in:
myResults <- lapply(aList, myFnc)
The goal would be to report on the progress of the lapply() function during
processing.
Any suggestion would be greatly appreciated.
Thanks
Marco
