sampsize uses the same sample for all the trees in the random Forest.
No.

But I want to use different sample for each tree of the 500 trees in the
random Forest. Thanks!

Hi!
I am dealing with random forest using R.
Is there a way to sample a fixed no.of rows from a dataset for use with
different trees in random Forest.
To be more clear, my data set contains 1500 rows, and I am growing 500
trees
in Random Forest
Is it possible to sample only 500 rows of data from the data set and use
it
for different trees in the forest. I mean each tree of the forest should
use
a different 500 rows from the data set.
See ?randomForest and the argument sampsize.

Thanks in advance!
