R help - Jun 2009 - kohonen SOM

Hi All,

I am experimenting with using binary data (1, 0) in the kohonen package.  I
would like either 1 or 0 to be mapped in SOM, but the package gives me 1 or 0
(as expected), but something in between.

I am not scaling the binary data, but still there are in-between values.

Can anybody suggest a way to keep the data binary, even in the SOM plot?

Thanks a lot.

George
