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.
How about Packages --> Install package(s) from CRAN...? You are making things unnecessarily difficult.
2) Also I tried to download it by copying the zip file first
tree_1.0-18.tar.gz
Zip files don't end with .tar.gz! These are tarred and gzipped source packages that you are almost certainly not set up to install. Your best bet is to try the simplest things first, which on Windows is to use the Packages menu.
Best,
Jim
<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.
