Confused on using expand.grid(), array(), image() and npudens(np) in my case
Hi all,
I want to use the npudens() function in the np package (multivariate
kernel density estimation), but was confused by the several functions in the
following codes,expand.grid(),array(),image() and npudensbw().
This confusion will only be generated in >=3 dimensions. I marked the four
places with confusion1-4. I think there should be some kind
of correspondence in those four places,but cannot figure them out.Thanks
very much for chewing on this.

- a new function for multivariate mixed-data copula and copula density functions (`npcopula') that exploits Li and Racine (2013)
Deprecated:
With these new methods we have deprecated the use of `cdf=TRUE' for density and conditional bandwidth objects (i.e. those generated with `npudensbw' and `npcdensbw') and decoupled this functionality into `npudensbw'/`npudistbw' and `npcdensbw'/`npcdistbw' (previously bandwidths optimal for PDFs were used for CDFs given the lack of methods for mixed-data CDF bandwidth selection).
