Hello:
I´m trying to execute Apriori(file.arff) command of RWeka package.
I´m working with:
Operating System: Windows XP home
R-2.4.0
RWeka_0.2-11
rJava_0.4-11
classpath= .;C:\Archivos de programa\Java\jdk1.5.0\lib;C:\Archivos de
programa\R\R- 2.4.0\library\RWeka\jar

An error occurs when .jnew command is executed, on class
"weka/core/Instances" :

>.jnew("weka/core/Instances")

Failed to create object of class ´weka/core/Instances´  and a warning
message: createObject.GetMethodID("weka/core/Instances","()V") failed

What can I do?
Thanks everybody.
