Hi
There is something weird going on with the "tree" package version
1.0-16.
So I want to download an updated tree package. I found that R website
has version 1.0-18. I want to try this one and see how the tree
algorithm is performing.
What is the best way to download tree package version 1.0-18 which can
be found in index of src/contrib at www.r-project.org?
So far I tried two different ways none of which has worked for me:
1) I tried to download it by running the command 
install.packages("tree","C:\Program
Files\R\rw1081\library","http://cran.r-project.org/src/contrib",destdir=
"C:\Program <http://cran.r-project.org/src/contrib",destdir="C:/Program>
Files\R\rw1081\library",installWithVers=TRUE)
But it tries to connect to
http://cran.r-project.org/src/contrib/bin/windows/contrib/1.8/PACKAGES
<http://cran.r-project.org/src/contrib/bin/windows/contrib/1.8/PACKAGES>
instead of the URL I enter above.
 
2) Also I tried to download it by copying the zip file first
 tree_1.0-18.tar.gz
<http://cran.r-project.org/src/contrib/tree_1.0-18.tar.gz>   in my
directory and then using the "Packages->Install package from local -zip
files" in the R menu. 
 
How can I download this version of tree? Thanks.
