Incidentally, if nxr is large, that code will run out of memory pretty
quickly and you're better off with an iterative solution like this:

goodpoints = lindgen(n_elements(Xr))
repeat begin
nowinc = where(Xr[goodpoints[1:*]] gt Xr[goodpoints], ninc,
ncomp=ndec)
if ninc gt 0 then goodpoints = [0,goodpoints[nowinc+1]]
endrep until ndec eq 0
