Cluster Analysis on Multivariate Raster Dataset - R script errors

Hello all!

I have a raster with 5 bands of data and I would like to perform a cluster analysis to group them.  I've tried the R script referenced in this thread but it consistently returns the following error:

<class 'arcgisscripting.ExecuteError'>: Failed to execute. Parameters are not valid.
ERROR 000732: Input Dataset or Feature Class: Dataset C:\Output.shp does not exist or is not supported
Failed to execute (DefineProjection).
Failed to execute (PointClusteringR).

I have tried several different output directories and file names - I do not understand why it keeps throwing this error code.  Does anyone have any idea why this is happening?

Alternatively, are there any other good tools for performing cluster analysis on a large, multiband raster dataset?  Thank you!
