[R] Problems with cclust

[Justin Arnott]

To Whom It May Concern,

I am currently trying to use R to perform a "kmeans" clustering of a
three dimensional data set.  In the directory
R-1.5.1/library/cclust/data/  I have created a file that
has the following format (only the first few lines are shown for
brevity):

            B                  X.Vtl     X.Vtu
1   -0.529043  1.307031  1.625169
2   -0.752502  1.132813  1.480548
3   -0.769839  0.888365  1.178828
4   -0.333035  0.732639  0.802276
5   -0.172183  0.636773  1.217721


The file has the name test3.tab in that directory.  When I then use R,
I load the data as follows:

>data(test3)

For a simple test, I attempt to use the kmeans method by using the
command that follows:

> cclust(test3, 2, method="kmeans")
Error in as.double.default(x) : (list) object cannot be coerced to
vector type 14


Below the command is the error I receive.  The matrix that I entered
does have columns corresponding to variables and rows to observations as
shown in the documentation so I'm not sure why it is not of the right
format.

Any help on how to "fix" this error would be greatly appreciated!!

Thanks,
Justin Arnott
