[R] Plot survey data

[John Fox]

Dear Anupam,

I may be wrong, but I don't think that there's any standard method to use 
in plotting with case weights. I can think of two approaches, however: (1) 
If you have a large sample, and if the range of the weights isn't too 
large, you could sample your observations with probability of inclusion in 
the plot proportional to the case weights. (2) You could plot the points 
with "size" proportional to the square root of the case weights (i.e., area 
proportional to the weights).

I hope that this helps,
  John
