Hello
I'd like to try out some functions in the package randomForest. Therefore,
I did install this package. However, it is not possible to load the
library, although I have R-Version 2.1.1 (i.e. later than 2.0.0). The
commands I used and the Answers/Error from R is as follows:
>
install.packages("C://Programme//R//rw2011//library//randomForest_4.5-16.zip",
lib="C://Programme//R//rw2011//library//randomForest",repos = NULL)
package 'randomForest' successfully unpacked and MD5 sums checked
updating HTML package descriptions
> library(randomForest)
Fehler in library(randomForest) : 'randomForest' ist kein g?ltiges Paket
--
vor 2.0.0 installiert?
I run in this problem for the first time. Until now, I used to install new
packages by copying the*.zip-file to the "library"-directory in the
rw2011-directory. This seam not to work anymore. So I tried using the
function install.package(), but I did not success.
Does anybody know the Problem? I did not find any hints in the NEWS.
Thanks anyway.
Ruth

Ruth, Does your R know about the library "C://Programme//R//rw2011//library//randomForest" ? I suspect that you want lib = "C://Programme//R//rw2011//library" in your install.packages() call. Or you could just leave the 'lib=' argument at its default. Peter Ehlers Ruth Meili wrote:> Hello > > I'd like to try out some functions in the package randomForest.

Most easily, you can install a package by simply saying install.packages("randomForest") if you have an active internet connection. Anyway, you might want to upgrade your version of R to R-2.2.1 or even R-2.3.0 beta (to be released next monday) and help testing. Uwe Ligges> I run in this problem for the first time.
