Hi all, The problem is solved uninstalling the R and restarting the system and installing it again. I don't know what caused the error but reinstalling the R was not enough and the system must be restarted.

When I run a simple code which uses a clusterer from RWeka I get an error. the sample codes and errors are mentioned below Code: library(RWeka) Cobweb(iris[,-5],control=NULL) Error: Error in names(class_ids) <- nms : 'names' attribute [150] must be the same length as the vector [0] In addition: Warning message: In is.nan(class) : is.nan() applied to non-(list or vector) of type 'NULL' another example of such an error is: Code: library(RWeka) cl1 <- SimpleKMeans(iris[, -5], Weka_control(N = 3)) Error: Error in names(class_ids) <- nms : 'names' attribute [150] must be the same length as the vector [0] In addition: Warning message: In is.nan(class) : is.nan() applied to non-(list or vector) of type 'NULL' I even copied the last code from Package RWeka manual but it still has the problem. for all clusterers in RWeka I have the same problem. I also used make_Weka_clusterer but the same error occures. I used different data sets and again the same error. I'm using R version 2.9.1 How can I use the clusterers of RWeka without any error? I'd really appreciate it if you could help me on this problem.
