> Subject: [R] A question about "txtProgressBar" function
>
> Hi,
>
> I tried to add a progress bar to my script, but it seems the
> "txtProgressBar" function will wipe out what I want to print before
> it(for example - the "Hello" in following script), and the parameters
> "title" and "label" do not work either. How can I put a title for the
> progress bar? or is there any other better function I can use?

> # create progress bar
> pb <- txtProgressBar(min = 0, max = total, style =
> 3,title="ProgressBar1",label="ProgressBar2")
> for(i in 1:total){
> Sys.sleep(0.1)
> # update progress bar
> setTxtProgressBar(pb, i)
