Hi,
I have a question about using RWeka Clusterers.If you could supply answer or
insight, I would really appreciate it.
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.
Thank you,
- Farid
