I am trying to use winProgressBar, however I find that although
setWinProgressBar updates the value on the screen, getWinProgressBar does
not return this value.
E.g
pb <- winProgressBar()
setWinProgressBar(pb, 0.2)
getWinProgressBar(pb)
[1] 0
It does, but rounded to an integer. Look at typeof() on the value, or
pb <- winProgressBar(max=100)
setWinProgressBar(pb, 20)
getWinProgressBar(pb)
It would be more flexible to allow the user to round, so I'll change it.
I tried the same with tkProgressBar, and it is working as I would expect
from the documentation.
pb <- tkProgressBar()
setTkProgressBar(pb, 0.5)
getTkProgressBar(pb)
[1] 0.5
... and I get the same result using txtProgressBar .
Does anyone using winProgressBar find the same behaviour, or know the reason
for it? A search for "winProgressBar" in R-help archive did not reveal
anything, I believe it is a new function to v2.7.0.
