`nbin` is for displaying the marginal events (i.e. those gray segments 
piled up at the edges)

`binSize` is for `timeline plotting`, i.e. when you do 'xyplot' on a 
`flowFrame` without 'formula` supplied , for example:

xyplot(GvHD[["s5a05"]], binSize = 100)

So again, 'xbin' is the argument to adjust the 'resolution'  for 
'non-smoothed' xyplot . e.g.

xyplot(`FSC-H` ~ `SSC-H`, GvHD[["s5a05"]], smooth = FALSE, xbin = 32) 
#lower resolution and faster rendering

xyplot(`FSC-H` ~ `SSC-H`, GvHD[["s5a05"]], smooth = FALSE, xbin = 128) 
#higher resolution and slower rendering
