"yes ......" is not responsive to the question of how you propose to
display or examine such a mathematical object. My signature was
perhaps a lame (certainly an ineffective) effort at getting you to
acknowledge that there might, just might, be some conceptual
difficulties in "viewing" a 5+1 = 6 dimensional object.
Can you point to any examples of such a procedure being applied in a
manner that you find helpful? It is certainly feasible to calculate
distances in 5-space, but the next step, displaying the
"concentration" of those distances as a function of the coordinates,
would be the "tough nut".
(1000 data points is not a problem. That amount of data should easily
fit in any device that can run R.)

I want a density estimator for 5 dimensional data.I want it to be
efficient since I don't have access to a fast computer.My data set
is quite large(about 1000 data points) and I have only a pentium 4
1.7 Ghz (512 Mb RAM)computer.

We can get you a kde2d but you really want a kde5d? What sort of

work for me. Is there any other function available which can do the

I don't have access to a very fast computer.
